Put a water filter. Water purification filter for a washing machine - which option to choose

From school, we know that water is a source of life, but experience accumulated over the years suggests that ordinary tap water can become a source of great health problems and cause breakdowns in household appliances. The thing is that it often comes to us, consumers, of extremely unsatisfactory quality. There are many reasons for this: from inadequate water treatment to worn, rusted pipes. It is hoped that in the future the situation will change dramatically, but for now, this problem has to be solved on its own, and all kinds of filters come to the rescue. We figure out how to choose a flow-through main water filter, a device that allows for the most thorough water treatment and provides high throughput.

No. 1. Is a filter really necessary?

A water filter is necessary in most cases. If it is about tenement house, then outdated pipes may be the cause of water pollution. which is often used in country houses and cottages, may be excessively mineralized or may not meet drinking water standards according to other criteria - it all depends on where the groundwater is located.

To the question is a filter really necessary, and if necessary, which one can only answer laboratory analysis. Water from the tap may be excessively harsh, which will suffer hair, skin and objects, in particular a washing machine, and a kettle. It may contain pesticides and pathogens, the dangers of which are probably not worth talking about. Water may contain some trace elements in an increased amount, which with regular use can cause specific diseases. In addition, water can smell foul, have an unpleasant taste, and even color.

In order for the filtration to bring the desired results, you first need to recognize the enemy in person, so experts recommend starting with checking the water at least for basic indicators. It may turn out that, for example, water softening is not necessary at all, and then the costs of analysis in the future will more than pay off.

No. 2. Why is the main filter better than others?

The problem of contaminated water is so widespread that mankind has come up with a lot of different devices for its purification. We will not go into details, but among most popular filtration systems   Today they use the following:

• jug type filters and dispensaries   do not belong to flow filters - a certain amount of water is poured into them, which is cleaned with built-in cartridges over time. This solution is suitable only for purification of water for drinking and cooking, since the volume of blood vessels, as a rule, does not exceed 3-4 l;
  
• filter nozzle on   allows you to purify water from large mechanical impurities, improve its organoleptic qualities. The filter is suitable if the water has a satisfactory quality, meets the standards, but you just want to improve it a little. Such a filter is easy to install, it can even be taken with you on trips, but it can’t cope with serious pollution, has low performance and requires frequent replacement of cartridges;
  
• filter "next to the sink"   also easy to install, connected to using a special adapter and provides an average level of purification, eliminating water from large contaminants and unpleasant odors;
  
• stationary filter “under the sink”installed under, allows you to purify water from mechanical impurities, chlorine, heavy metals, eliminate odors and tastes. This is a very popular system, it is easy to maintain, requires the replacement of cartridges every 5-6 months, but the cost of its arrangement is higher than the previously listed options. This solution has some disadvantages. The filter will not cope with the most serious impurities, it has limitations in terms of performance and cannot be installed on pipes with hot water.

If any of the above filters allows you to purify the water to an acceptable quality, you are very lucky. But if you are not lucky, then you should not be upset, because there are flow line filterswhich actually represent miniature water treatment plant.

The main filter is built into the water supply system of the apartment or house, crashes into the water main and creates a serious barrier to the water entering the apartment, which, passing through the filter system, is cleaned of mechanical impurities, harmful elements and compounds. Filter can be set to hot and cold water, and since it will stand at the entrance, purified water will flow from all the taps.

The flow line water filter is usually used in houses that have their own water supply   (well or well), but recently a similar system is often installed and in apartment buildings where water pipes are badly worn.   Similar filters allow solve several problems at once:

• purification of water from harmful impurities, chlorine and microorganisms;
• improving the taste of water and getting rid of metal and other flavors;
• softening, because hard water negatively affects the skin and hair, leads to the rapid wear of some household appliances;
• maintaining plumbing equipment in good condition. Conventional (non-main) filters purify water only at one point of consumption, and along the remaining pipes in the apartment it runs silted and contaminated with particles of rust and other garbage, which gradually breaks down. With the main filter, this problem disappears.

The main advantages of main filters include:

• high cleaning efficiency;
• high performance (the filter purifies 20-50 liters of water per minute);
• variability. Depending on what it is necessary to purify water from, various cartridges can be used;
• the ability to purify water for all points of intake with one filter;
• durability subject to proper operation.

Among the disadvantages   we note only the difficulty in installation - we need the help of specialists. You can service the main filter yourself, but if clogging occurs, you can hardly do without a professional. The cost of the trunk systems, of course, is higher than that of simpler filters, but it is not sky-high.

No. 3. The main principles of the main filter

Since the main filter is installed at the "entrance" of the water pipe into the apartment, it allows clear water for all points of intake. The main filter is multi-stage cleaningmoreover, the purpose of all stages of cleaning can be determined independently, collecting the system that is optimal in specific conditions.

The following elements may be present in the design of the main filters:

The throughput of flowing main filters is, as a rule, from 20 to 50 l / min or more, which is sufficient for normal operation in any apartment or house. Requirements are put forward to system pressure.   Main filters can be low (0.1-0.2 bar) and high (0.4-0.5 bar) water loss. If you live on a high floor, where the pressure in the water supply is already low, it is better to take a filter with minimal water loss.Additionally, a main pump may be needed.

For more productive work, the system does not interfere with equipping pressure reducing valve, which allows you to reduce pressure fluctuations in the system and reduce water consumption. A non-return valve is also needed - it will prevent backflow of water.

When choosing a main filter, it is also worth considering the pipe diameter, maximum operating temperature and the number of existing water intake points.

Number 4. Types of trunk filters

To ensure the proper degree of water purification, the main filter is equipped with several filtration systems, and their set will depend on what the water is polluted.

The main filter may include the following components:

• strainer line filter, or coarse filter, allows you to save water from mechanical pollution, which is especially true in homes with old utilities. The filter is represented by a stainless steel mesh or other material with a cell size of 10 to 200 microns: the smaller the cell, the more debris the filter can hold. Often, strainers are installed in the trunk system in front of the cartridge to reduce the load on them. The mesh, and sometimes there may be several, has an actual unlimited service life - it is enough to clean it only occasionally. If all the cells are clogged so that they are not cleaned, you will have to take a new mesh. There are filters with a backwash system, which are also called self-washing filters. Strainers may vary depending on where they are used in cold or hot water systems. Any filters are suitable for cold water, only steel or special plastic for hot water;
  
• disk trunk filters, or fine filters, cleaned of mechanical impurities more thoroughly and use several technologies at once. These are blocks of pressed polymer disks with grooves, which, when compressed, form a grid that traps the smallest particles of dirt. Flushing such filters is easier. Sorption cartridges and ultraviolet filters can also be used;
  
• cartridge line filters   provide the highest quality cleaning. They allow you to filter out particles from 5 microns in size, can get rid of iron, chlorine, salts, microorganisms and saturate the water with oxygen - this is an even more subtle and targeted cleaning. You can use several different cartridges at once. Cartridges will have to be replaced more often than cleaning nets and discs, but the quality of cleaning is much higher here;
  
• reverse osmosis filters rarely used and allow due to the passage of water under pressure through the membrane at the outlet to get clean distilled water. Similar systems can be installed if the pressure in the water supply reaches 3-4 atmospheres.

By the number of cleaning steps, the main filters are divided into:

• single stage;
• two-stage;
• three-stage.

Again, the choice depends on the quality of the water.

No. 5. Types of cartridges for the main filter

Chemical water purification is achieved through the use of cartridges. They can be:

No. 6. Water Filter Manufacturers

When it is decided what and how we will purify the water from, the time comes for an equally difficult choice - it is necessary to determine the equipment manufacturer. It is better to trust eminent companies, among which it is worth highlighting:

• geyser company   produces filtration equipment that can be installed on hot and cold water pipes. The manufacturer offers several ready-made systems designed for water purification for different purposes. There is, for example, a system for protecting plumbing equipment. The company sells filters and cartridges of various types for mechanical and chemical water treatment;
• aquaphor company   produces trunk filters of small sizes, but at the same time the systems allow high-quality cleaning of mechanical impurities, chlorine, iron and salts of heavy metals. The equipment is made of stainless steel, which withstands a wide range of temperatures, and plastic, which is designed for operation at a temperature of + 5 ... + 40 0 \u200b\u200bC;
  
• trunk filters "Artesian"   They feature a convenient cleaning system, or rather self-cleaning. Strainers are complemented by a special string that vibrates under the influence of a stream of water, not allowing pollution to linger in the pores of the filter;
  
• company filters Atoll   provide high-quality cleaning and are carried out in transparent cases. This is not only a plus for aesthetics, but also the opportunity to observe the cleaning process. The company's assortment has filters for cold and hot water with a capacity of up to 60 l / min.

All these flow-through main filters http://v-filter.ru/kupit/protochnye-filtry/, as well as many other devices for water purification, can be purchased in the store of Crystal LLC.

In some countries, such as India, drinking tap water is dangerous: you may get an upset stomach or an intestinal infection. In Russia, the situation with water supply is better, but many still use the filter. Why is it necessary and which device is more effective?

In large cities of Russia, water supply stations guarantee the safety of tap water. But before you get to our crane, the fluid goes through the pipes. Many pipes are old, rusty and worn. Through them, harmful substances get into the water from the tap.

Someone does not drink tap water, because he feels a suspicious taste in it. But even if the water tastes normal, it is not a fact that it is safe. To check if it contains impurities and impurities, contact the sanitary-epidemiological service and hand in a sample of the fluid for inspection.

You can approximately determine the quality of water yourself:

• If scale appears in your teapot, white stains remain after washing the dishes, and after brewing tea, a film appears in the mug - the water is hard, that is, it contains a lot of salts.
• Putrid taste of water indicates the presence of hydrogen sulfide, and tart - an excess of iron.
• If after washing the clothes appear gray, it means that there is manganese and heavy metals in the water.

In addition, you can look at the Internet project of Rospotrebnadzor "Water Map of Russia". The site has a map of laboratory water tests in different regions. Most of the research is in the Moscow region.

Someone prefers bottled tap water from the store, but here there are some nuances. According to experts, bottled water does not always meet safety requirements. The list of “unsafe” brands is on the Roskontrol website. In addition, the water from the store is usually more expensive than filtered at home. Therefore, many begin to buy filters.

The filter improves the quality of the liquid: cleans it of heavy metals, impurities, viruses and bacteria. The worse the water, the more powerful and expensive the device is needed. We made an overview of the types of water filters and at the end of the article gave recommendations on their choice.

Coarse or mechanical cleaning   - from large solid particles of sand, rust, clay, etc. Coarse filters are mesh made of steel or polymer materials with small mesh.

Filters fine cleaning   use the following technologies:

• Sorption purification   - from, chlorine, oil products and other harmful compounds. Water during treatment passes through a sorbent - as a rule, it is activated carbon.
• Ion exchange - water passes through ion-exchange resins. As a result, magnesium and calcium ions, which give water rigidity, are replaced by harmless sodium atoms.
• Reverse osmosis   - The most effective cleaning technology. Under pressure, water passes through a membrane that passes virtually nothing but the liquid itself.
• UV disinfection   - eliminates the majority of microorganisms. In urban water supply centers, water is already being treated with ultraviolet light, so it is more likely to need water from a well or well.

Types of filters for water purification in the apartment

The most popular filter in the kitchen for drinking water. The device consists of three parts:

• Jug   made of glass or plastic. The volume of the container is 1.5–4 liters.
• Receiving bowl, or a funnel takes up almost half the jug. A cleaning cartridge is attached to its bottom.
• Cartridge   purifies water. It must be replaced periodically: depending on the model, it is designed for 100-450 liters. There are cartridges with and without thread. The latter can be installed incorrectly, then untreated water will leak into the tank.

Liquid flows through several cleaning layers inside the cartridge:

• prefilterretains solid insoluble particles;
• activated carbonremoves most harmful organic compounds. This is usually the main filter component;
• ion exchange resinssoften water and remove impurities of heavy metals;
• silver iodide   kills bacteria;
• post filterblocks the ingress of particles of filtering materials into the water - for example, the same coal.

Consumables sometimes contain minerals and trace elements that make water more healthy.

Pros:

• A filter jug \u200b\u200bis a budget option. A jug costs from 300 rubles, a cartridge - from 150.
• No need to understand the installation, use is simple: poured water, waited, drank.
• The jug does not take up much space, it is easy to lift and carry.

Minuses:

• Low productivity. Water flows slowly, so the jug is designed for a family of two to three people.
• May not remove all contaminants. If the tap water is of extremely poor quality, you should purchase a more powerful device.
• Small tank volume.

When choosing a jug, pay attention to which cartridges are compatible with it and how long they last.

The principle of operation is the same as that of a jug: water passes through a cartridge into a reservoir. Only in volume the tank is more capacious; on it is a small tap through which water is poured. Typically, dispensers have a longer cartridge life than jugs. This type of water purifier is optimal for small offices and families of more than three people.

The nozzle is attached to the mixer and purifies the water from chlorine, rust and fine suspensions. Inside is a cassette (cartridge), which must be changed once every one to three months. The main filtering component is activated carbon.

Pros:

• Relatively inexpensive - from 170 rubles.
• Easy to use and install.
• The cleaning speed is higher than that of filter jugs.

Minuses:

• It is necessary to constantly remove and put on the nozzle, so as not to waste purified water on washing dishes and other needs.
• If an excessively strong flow of water passes through the device, the quality of the filter may decrease.

The filter for the apartment is placed near the sink and connected to the mixer using a flexible hose. The device has its own tap, from which purified water is supplied. The cartridge needs to be changed every 2–4 months.

Pros:

• Easy to use.
• Productivity is higher than that of jugs and nozzles - about two liters per minute.

Minuses:

• Need free space next to the sink.
• The price is higher than the previous types - from 1,000 rubles.

Other names - prefilter, filter of mechanical (preliminary) cleaning. They cut it into the highway of cold or hot water supply. It is needed primarily for the protection of plumbing, dishwasher and washing machine. It is also used as a filter for cleaning water from a well.

For cold water, a standard prefilter is used, and for hot water - from heat-resistant materials. The service life of such devices is up to 30 years.

The prefilter is not a panacea. It removes only large insoluble impurities, thus extending the life of the main filter.

Main filters are divided into several types:

• Strainerstrap large particles of contaminants with a mesh. The smaller the grid cell, the more particles of different sizes it will hold. There are flushing and non-flushing devices. First, dirt is automatically washed off with running water. To clean the non-flush filter, you need to rinse the mesh yourself.
• Disk Trunk Filters   also cleaned of mechanical impurities, but their performance is higher than that of mesh. Filter elements - pressed polymer disks. When the discs are compressed, the grooves on them form a grid. They need to be washed in a timely manner under running water.
• Cartridge (cartridge) filtersare replaceable cartridges. They need to be changed much more often than the grid or disks, but the quality of cleaning is higher. Cases of cartridges for cold water are made of transparent or opaque plastic. Transparent is more convenient, because through it you can see how dirty the cartridge is. For hot water, the housings are made of opaque heat-resistant plastic or stainless steel. Cases come in different sizes: the larger they are, the higher the performance of the device and the longer its service life.

You can insert the device into the water supply yourself, but this is a laborious procedure. If you are unsure of your abilities, ask a specialist for help.

Prices for the prefilter start at 1,500 rubles; there are models for 13,000.

When buying this type, you need to know the diameter of the cross section of the water pipe and the temperature of the water for which the device is designed.

Pros:

• Do not require frequent replacement.
• Serves for many years.
• High performance
• Easy to use.

Minuses:

• Removes only large particles.
• The prefilter is difficult to install without the help of a specialist.
• To replace the cartridge in cartridge form, it is necessary to shut off the water supply.

These are the most effective household filters for treating tap water. Water goes through several stages of purification, disinfects and softens. The system contains 3-5 sections - flasks with cartridges. Cartridges are replaced after six months or a year.

Need free space under the sink and a place for the output of an additional tap. The liquid is supplied through a separate mixer with a filter for drinking water. The device is connected to water pipes.

Filters "under the sink" are of two types - flowing   and   reverse osmosis.

Flowing water filter consists of three to four modules (cartridges):

• pre-cleaning   - from sand, rust, silt;
• carbonic   - from chlorine, salts, organic compounds, heavy metals;
• with ion exchange resins   - for iron removal and water softening;
• with small particles of silver- cleanses bacteria.

You can experiment with a set of cartridges - this way you will adjust the degree of water purification.

Some models are equipped with an ultraviolet lamp - it destroys dangerous microorganisms.

Reverse osmosis system   - A special case of the type "under the sink." Comparison of water filters shows that this is the most effective option. In such a system, water can be purified 99%.

Cleaning goes through the following steps:

1. A prefilter purifies water from large contaminants;
2. Water passes through the membrane - a material twisted into a roll, pore size 0.0001 microns. The membrane passes only water molecules, all other compounds are discharged into the sewer by a forced fluid flow.
     Then the water accumulates in the tank with a volume of 4-12 liters.

Membranes are not changed as often as cartridges - its service life is 1–5 years. The performance of household reverse osmosis systems is 150–300 liters per day.

After such a thorough purification, useful mineral substances are also removed from the water; therefore, a mineralizer is built into the reverse osmosis system. This is a cartridge with a mineral filling, which gradually dissolves in water, saturating it with magnesium, calcium, zinc, iron and other elements. Mineralization improves the taste and quality of water. Cartridge resource - 3-4 thousand liters.

Even in a new house you can not do without installing filters for water and air purification. They are necessary to protect metering devices installed in the home equipment, as well as providing clean drinking water.

Particular attention should be paid to air purification systems, especially if children or elderly people live in the house.

The choice of equipment today is very large, so many are lost in the types of filters and can not choose the right model.

The quality of water and air in different regions can vary significantly, so there are no unified recommendations for the installation of filters. In each case, devices are selected individually.

Why installation of water filters in the apartment is required

First of all, in the new apartment, care must be taken to install the main filters for cold and hot water. They perform cleaning from sand and other contaminants, and also eliminate turbidity of the water.

According to the type of cartridges used, they are divided into:

• mesh,
• corrugated
• with wicker, foam propylene,
• winding.

According to the degree of purification, the following types are distinguished:

• single-stage - purify water by 98%, it is necessary to change every six months,
• two-stage - in addition to cleaning from mechanical impurities, chlorine, organics, various impurities are retained,
• three-stage - additionally remove excess iron, soften water.

The installation of the main filters must be carried out separately for both cold and hot water.

Of the most popular trunk manufacturers flow filters for an apartment   It is worth noting the following:

1. Aquaphor - the company produces devices for treating drinking water, as well as protecting household appliances from rust, sand, and chemical compounds.
2. Honeywell - products of the German brand, designed for rough and fine water purification, a metal mesh enclosed in a flask acts as a filter element.
3. Geyser - manufacturer produces trunk filters based on ion-exchange polymer.

It should be borne in mind that when buying plumbing fixtures, washing machines and other household appliances, the guarantee will not apply if the apartment does not have the appropriate filters.

Do I need filters for drinking water in the apartment

For the purification of drinking water in the apartment, jug filters are used, which can be purchased at any store. They do not require installation, but also do not differ in high efficiency, therefore, experts still recommend installing flow-through devices.

They are represented by the following types:

• nozzles on the crane,
• filters connected to the water supply as needed,
• stationary devices permanently connected to the water supply.

They perform cleaning from:

1. chlorine and all its forms,
2. excess iron
3. heavy metals
4. hardness salts,
5. microorganisms and bacteria,
6. rust, sand.

The first view is similar in principle to jug filters. Water purification is slow, and multiple filter elements cannot be connected.

The second type is more economical and efficient, as it can be connected to the tap from time to time. Installation is carried out using a flexible hose, the design itself is quite cumbersome, but it is characterized by high performance and a long service life. The filter is able to purify water from salts of heavy metals, as well as microorganisms.

The third type is the most effective, but also the most expensive. It is connected in parallel to the main crane and consists, as a rule, of several components. The high performance of the device is achieved due to the reliable installation, which eliminates the breakdown of the device even with serious pressure fluctuations. It is convenient to change cartridges in this design without the help of specialists.

Most often installation filters for drinking water purification in an apartment   performed under the sink, as:

• the design will not take up much space,
• the ability to quickly replace cartridges will remain.

VIDEO ON THE TOPIC

Among the manufacturers of home filters for drinking water purification for an apartment are the following:

1. The geyser offers the models “Standard”, “3 VK Suite”, “3 K Suite”, “Bio 341”, “Bio 311” and others. Each of the filters is selected based on the characteristics of the composition of water. For example, “Bio 311” is used for soft water, and “Bio 341”, on the contrary, for hard water.
2. Aquaphor produces Crystal ECO, Fe Trio, and Norma Trio models. Filters differ in the number of degrees of purification, size, performance, but in general they provide protection against chlorine, hardness salts, bacteria, heavy metals, viruses.
3. Atoll manufactures filters "U-31s STD", "A-313 E gr Lux" for protection against scale, as well as eliminating stiffness.

In stores you can buy both budget options and more expensive designs.

Should I buy a filter to clean the air in the apartment

Air purification in the apartment is another important issue that needs to be addressed. Exhausts from highways, industrial waste, dust and dirt from the street do not always give the opportunity to ventilate the room so as not to harm itself. In this regard, manufacturers offer several options for filters for air purification.

Mechanical or air devices:

These are strainers that can trap large contaminants. They require cleaning with warm water or a vacuum cleaner.

• Electrostatic

Hold up to 95% of dust. They work on the principle of mutual attraction of bipolar electrostatic charges. First, air enters the ionization chamber, where its components acquire a positive charge. Then they are attracted by plates with a negative charge, as a result, the particles settle on the filter. To wash the device, warm soapy water is sufficient.

• HEPA filters

Originally developed for medical facilities. The devices are based on porous fiberglass material. It retains up to 99% of small contaminants, allergens. It can not be restored after the exhaustion of the resource, and also has a fairly high price.

• Coal

They work on the basis of activated carbon, which absorbs unpleasant odors and gases. Generally used as an adjunct to other cleaning devices. After working out the resource, they require a complete replacement.

In modern air purification systems, several filter options are usually used at once, due to which a qualitative result is achieved.

Of the most popular options for air purification devices, it is worth noting:

• photocatalytic cleaners: decompose impurities to water and carbon dioxide, successfully cope with the elimination of viruses, toxins, carbon monoxide from the air;
• air purifiers with ionizers: enrich particles in the air with an electric charge, as a result, they settle on horizontal surfaces (the filter itself does not require cleaning and recovery, but it will be necessary to clean the room more often),
• air washing: in addition to cleaning, they perform the function of humidification, do not have replaceable elements, but need constant filling with water.

When choosing air filters in the apartment   It is worth considering several factors.

If people suffering from allergic or respiratory diseases live in the apartment, you should pay attention to devices with the HEPA filter, since it is it that retains dust most qualitatively.

If there is a small child in the house, a humidifier filter will be useful, since it is recommended that children breathe not too dry air.

As additional features will be useful:

• timers that turn off the device in automatic mode,
• pollution detectors,
• the ability to change the speed of work, and therefore the noise level and performance of the device.

Do not forget about the difficulty of replacing the filter elements and the maintenance of the device as a whole. If you are not ready to spend a lot of time and effort on maintaining the operability of the device, choose photocatalytic filters that require flushing only once every six months.

Before you go to the store, decide where exactly you will install the device, since many models require special conditions for installation. If you are not ready to spend money on regular replacement of an expensive filter element, purchase a device without them.

The World Health Organization notes that most human ailments are caused by poor quality drinking water. And that even a “respectable” looking liquid can conceal a lot of harmful components. To all who value their own health and the health of their loved ones, experts recommend purchasing water filters - we will tell you how to choose them.

Methods for purifying water from a well or water supply system

To purify water from harmful substances, it is necessary to pass it through a special medium - this is the principle of filtration technology. Depending on the type of medium used, there is a change in the properties of the liquid. Different filters use their work resources. To ensure the acceptable content of impurities in the liquid, they must be changed before the resource is completely exhausted.

Mechanical

Mechanical water treatment is preliminary

Mechanical filtration is carried out in order to remove insoluble mineral and organic impurities from water. A positive quality of this process is the ability to use it at normal temperature without adding chemicals. Typically, this treatment is a preliminary, in rare cases, the final method of water treatment.

Sorption

Overall dimensions are a significant minus of sorption treatment systems

Sorption purification of a liquid implies the use of porous materials that bind and retain impurities. Carbon filler is often used. It is effectively used in the presence of inorganic and organic substances in water, as well as chlorine compounds.

The main disadvantage of sorption filters is the very large dimensions of these devices. The filling of them takes place in several layers to ensure the most complete release from hazardous substances.

Charcoal filters require proper care. Only professional service guarantees high-quality and efficient filtration. Since bacteria can settle in the pores of coal to rinse it, use hot water.

Ion exchange cleaning

Such systems are expensive

However, ion-exchange purification alone will not be enough, since such filtration:

• does not remove heavy metals, minerals and pesticides;
• ozone, in contrast to chlorine similar in effect, decomposes very quickly and there is no residual cleaning effect.

Also, ozonation of water will cost a lot, for this reason it is not a good idea to use ion-exchange purification at home.

Membrane

Membrane system provides a high degree of water purification

With membrane filtration, high purification is achieved due to the exact division into elements of impurities present in the liquid. The main advantage of using membranes is that impurities will not remain there, their removal is due to the drainage system.

However, this method of water purification has one nuance: during processing, the accumulation of impurities occurs extremely close to the membrane itself. A similar phenomenon is called concentration polarization, which can affect the filtration results and reduce the membrane properties.

Electrochemical

When using this method, an electric current is passed through water

During electrochemical purification of water, an electric current passes through it, as a result of which the impurities contained in the liquid usually decompose into non-toxic substances.

The main advantages of this method are the small size of the complex, ease of operation, lack of need for reagents, effective bactericidal cleaning. However, there are certain disadvantages, namely, low productivity and high energy intensity.

UV disinfection

UF disinfection is an environmentally friendly way to clean

UV disinfection is considered universal because it destroys all types of contaminants. The environmental friendliness of the cleaning method, its low cost and the lack of need for expensive after-sales service are also noted. After filtration, the water structure does not change, and all useful elements are stored in it.

Which cartridges to choose

The choice of cartridge will depend on the filter used and on what kind of result you want to achieve.

For jugs there are cartridges with several types of cleaning, in flow and main lines each type of cartridge is designed for a certain type of cleaning, there is also a comprehensive cleaning.

Depending on the type of cartridge, it can perform one of the functions listed above.

When choosing, consider a few simple rules:

• mechanical cleaning is required with a filter fineness of 1 or 5 microns;
• on the riser, water must pass through a mechanical deep cleaning of 10 or 100 microns;
• if you want to get rid of iron, choose a cartridge containing components designed for this;
• to mitigate, it is better to take cartridges with ion-exchange resin;
• to improve the taste of water and clean it of chemical impurities, pay attention to carbon cartridges.

The choice of system depending on water pollution

The efficiency of the use of the purification system and the quality of the filtering liquid depends on the specificity of the existing pollution. Before deciding on a water filter, you need to carry out a comprehensive impurity. Only after that it becomes clear what to choose.

Additional options to keep in mind when choosing a filter

Now you should familiarize yourself with additional parameters that you need to pay attention to when you move on to choosing a filter for water treatment.

There are several other factors to consider when choosing a filter system.

Cold and hot water filtration

Most of the cleaning devices are designed to filter cold water. The maximum allowable temperature in this case should not exceed 400C. For this reason, if you want to purify hot water, then you should look for filters with a high temperature limit.

Filter module performance and resources

Under the performance of the filter is meant its ability to pass and purify a certain amount of water per minute. This indicator is minimal for reverse osmosis systems, since it takes a lot of time for the liquid to pass through the filtering membrane. So, when choosing a filter, you need to decide how often it will be used and how much water will need to be cleaned per day.

Almost everyone has a filter module, designed to clean a specific volume of water. As soon as its resource is exhausted, it will not be able to provide adequate water quality and it will have to be replaced.

Supplies Availability

You need to pay attention to the cost of filtering modules - cartridges, since in most filters they quickly exhaust their working resource, which means that they will have to pay a lot.

Any cartridges have their own working resource.

Manufacturer's choice

It is no secret that both domestic and foreign companies are engaged in the production of filtration units. Some have been realizing themselves in this area for more than a decade, while others are only embarking on this path without focusing on water purification systems.

If you can’t decide which is better, we recommend that you abandon the stereotypes that “they say everything foreign is better, better, more reliable”, and choose products from experienced companies with a name and positive reviews. Such, by the way, is enough in the Russian market. It is enough to look into the rating of water filters to understand that “our” companies are able to make solid, durable units.

It is better to stop the choice on products whose manufacturers have long been working in this market and have been able to recommend themselves well. Each of them has its own developments for different cleaning systems.

Cost

If the price of the desired model is very different from the average market value, then you need to think about where this product comes from. If this product was purchased from an official supplier, but the price is very different from the prices in other stores, then this is a complete fake.

Certificate availability

If you doubt the quality of the goods, you can ask the seller for a quality certificate. Moreover, this document should be genuine, and not an ordinary photocopy.

Which water purification filter to choose for an apartment and a house

These units may vary in technical specifications and in device design. Therefore, when deciding which filter to choose for a house, apartment or summer house, it is very important to clearly define your needs and objectively coordinate them with real possibilities.

The effectiveness of the filter depends on which filter is selected in each case. Modern manufacturers are ready to offer many models of different treatment equipment and filters.

Prefilters

Prefilters purify water from solid impurities

Prefilters are used to purify water from solid impurities that significantly impair its taste and can harm household appliances. When choosing a specific model, consider the amount of water consumed.

Mud Filters

Mud filters are used for mechanical cleaning of water. She, passing through a special mesh, leaves solid impurities on it. Sumps can be used for pre-treatment of cold and even hot water up to 150 ° C.

Jug

Jug filters - the most affordable water purification device

These are the most primitive devices, the resource of their cartridges is very small (as a rule, up to three hundred liters). Their main purpose is to rid the water of chlorine and unpleasant odors, and partly of hardness. Pitchers are mobile and compact; they can be successfully operated both at home and on the road. With them, clean water is always at hand. Cartridge replacement frequency - once a month. The maximum degree of purification is 20 microns.

Benefits:

• does not need to be connected to a water supply system;
• extremely easy to use, does not require human control.

Disadvantages:

• in them the degree of purification is an order of magnitude lower than in those “integrated” into the water supply;
• small volumes of purified water.

The amount of liquid purified at one time cannot exceed the volume of the jug itself — usually one to two liters. That is, if three liters of water is required for cooking, one way or another the jug will have to be filled twice. And this is not always convenient.

A jug filter is the best option for those who have a fairly limited budget or, due to the small size of the kitchen, cannot allocate a place under the sink for a stationary system.

Crane water purifiers

The filter nozzle has a compact size and an affordable price

These are small-sized devices, dressing directly on the crane. Their advantages are low price and the ability to take with you on trips.

Disadvantages - low sorbent volume and low productivity - up to half a liter per minute (if the advertising slogans of manufacturers say that you can do it faster, do not believe it). And here, storage tanks for purified liquid are also needed.

Dispensers

Dispenser filters designed for water purification

Dispensers are used to carry out post-treatment of drinking water at home. They are easy to use, since you do not need to connect this filter to the water supply.

The filter eliminates unpleasant aftertaste and odor. Replaceable cartridges can clean solid suspensions, a variety of organic and inorganic impurities and soften water.

Flowing to the sink

The cartridge is located next to the tap and is connected using a flexible hose.

Such water purifiers are not put on the tap itself, but are placed nearby. Such installations are attached to the crane using a flexible hose.

Their main advantages are sufficient productivity (higher than that of the nozzle on the crane) - up to one and a half liters per minute. Plus, there is no need for separate tanks for purified water.

But such a filter occupies a precious place in the sink. True, if he is handsome, this item can be excluded from the rank of shortcomings. Well, it should be remembered that it requires connection and disconnection after water treatment.

Flowing water filters for washing

Such a filter has many advantages, but unfortunately, the price is high

The stationary filter under the sink is built into the water supply. The unit itself is located under the sink, and a separate faucet is brought out onto it - exclusively for purified water. Cartridge change frequency - once every six months. The maximum degree of purification is 0.05-1 microns.

Benefits:

• high degree of water purification;
• sufficient performance;
• large resource;
• the presence of a separate tap for purified liquid;
• ease of use;
• the required volume of purified water is always available;
• location under the sink - no clutter of the workspace.

The disadvantage is the high price.

Stationary filters are chosen by those users who understand the value and importance of highly purified water and are willing to invest in their health.

Softeners

The disadvantage of the system is that it does not purify bacteria and metals

Water softens as a result of a decrease in the amount of salts, usually chlorides and sulfates. For this, replaceable filters with a cation exchange resin adsorbing salts are used, instead of saturating the water with hydrogen and sodium ions. The downside is that softeners do not cleanse bacteria and metals.

Home Reverse Osmosis Systems

Thanks to reverse osmosis systems, it became possible to obtain water at home that is not inferior in quality to bottled water

These are perhaps the best water purifiers to date. They allow you to remove not only the excess water hardness, excess iron and chlorine, but also all kinds of bacteria and viruses.

A key filtering component of such systems is the reverse osmosis membrane. Its pores are much smaller than most known viruses, therefore, your body will be protected as reliably as possible.

The main advantages of reverse osmosis systems over other treatment plants:

• highest degree of purification;
• low cost of purified water;
• a constant supply of fluid (ten liters).

The complete set of such installations looks like this:

• pre-filter cartridge system;
• reverse osmosis membrane;
• special post-filter.

These units, if desired, can be understaffed with a structurizer and mineralizer - this will make the water rich in useful minerals, able to improve digestion and blood circulation.

The maximum degree of purification of such systems is 0.0001 microns. The frequency of replacing the reverse osmosis membrane is once every three years. The frequency of replacing post-cleaning cartridges is once a year.

Reverse osmosis systems are chosen by people who want to constantly consume highly purified water without overpaying for it (bottled products).

Trunk

Main filters are installed in the water supply

Filters of this type are mounted directly in the water supply. They are designed to purify water from mechanical formations and chemical compounds. By type, they are divided into coarse and fine cleaning systems, as well as for softening water.

The most suitable apartments or houses of medium size are units that can skip from 20 to 50 liters per minute. But in some cases, the calculation of the required power is individual and depends on the maximum amount of water consumption. In addition, it should be borne in mind that the pressure in the water supply system should correspond to 0.1 - 0.5 bar.

The service life depends on the intensity of use and can even be unlimited with proper operation, with the condition that you need to wash the cleaning cells.

Benefits:

• thanks to a comprehensive cleaning of bacteria and technical impurities, the palatability of water improves;
• significantly increase the life of water pipes and household appliances;
• it is small in size, easy to use, and filter components can be replaced on their own;
• another advantage of these units is the low price of replaceable cartridges.

There may be one drawback - the installation process. If you have not been involved in the installation and connection of the water supply, then most likely you will need the help of a specialist. But this is not such a serious minus.

Fibos-type main filters with flushing system

Unlike sumps and strainers, Fibos filters fine-tune water. Their filter element is made in the form of a cylinder with a wound coil to a coil of ultra-thin microwire. The distance between adjacent turns in the winding does not exceed 1 micron. This allows you to retain not only dirt particles, but also 99% of the bacteria that form a biofilm on these particles. To prevent the Fibos filter element from becoming contaminated, the microwire is coated with a thin layer of glass insulation to prevent particles in the water from sticking to the microwire.

Microwire is a unique technology developed back in the USSR for defense and space purposes; the only mass production in the world is in Russia.

Fibos filters are directly flushed through an outlet tap into any suitable cookware or sewage system. An additional device allows you to automate the washing process.

The performance of the Fibos filter range has wide limits. Practically without reducing the pressure in the water supply system, filters purify 5 liters of water per minute when used in the kitchen under the sink, 16 l / min when cleaning in the apartment or in the country, 50 l / min in the cottages, 83 l / min in the cottages, pools , up to 1000 l / min in production.

Since Fibos does fine water purification, if necessary, inexpensive cartridge filters can be installed after it to soften water, lower iron content, and remove chlorine. The life of the cartridges in this case is significantly increased.

The cost of Fibos filters is from 7990 rubles with a service life of more than 10 years. Filters work in both cold and hot water supply systems up to + 95 ° C.

Fibos fine filter - the leader among main filters

Postfilters

Such filters improve the taste of water.

Post-filters are used in reverse osmosis systems in order to eliminate an unpleasant odor and improve the taste of water. The active element here is activated carbon. Also, mineralizer filters are used in these systems. They are necessary to restore the natural mineralogical composition of water, which is disturbed after the passage of fluid through the membrane.

General requirements for water treatment systems for a house or apartment

Since the filter is constantly in contact with drinking water, it must be made of environmentally friendly, safe materials that do not emit any chemistry or a characteristic odor. Just smell the plastic parts and you will understand whether the product is in front of you or not.

For high-quality water treatment system, all cartridges must be replaced in a timely manner.

For a stationary system connected to a water supply system, strong, durable housing materials are very important. Modern high-quality water purifiers are made of glass-filled plastic - it is much better than usual.

The choice of a water filter should be entirely based on the principles of common sense - it’s not naive to assume that the jug type unit will serve you for ten years. But if you are single, accustomed to an active lifestyle just like that (or a nozzle for a crane) will suit you best. For a large family, it is almost impossible to overestimate the convenience and significance of a stationary device.

Any of the cartridges used in the cleaning system has its own resource, which, if exhausted, should be replaced. Usually it is expressed in the volume of liters of treated liquid or the time of use, but taking into account the average norms of water consumption per day. The filters used for mechanical cleaning sometimes need to be cleaned of accumulated dirt. If the operating rules are not followed, then the system will pollute the water instead of cleaning it.

Water purification filter for a washing machine - which option to choose. What filter to put at the entrance of cold water to the apartment

Which filter is best for water purification in the apartment

In this article you will receive truly valuable and comprehensive information about what water purification is in an apartment, how it works and what removes, how to choose what you need, how it relates to everyday life in everyday life and what benefits you get. After all, water is the most consumed product!

Water purification for an apartment is a hot topic today. The city water main supplies pre-purified water, so the filtering systems for apartments are more compact and not as bulky as for houses and cottages. Water in urban highways is cleaner than in wells and wells, therefore, the resource of replaceable materials and elements is longer. But despite the pre-treatment of main water by urban filtering systems, it has pollution exceeding hardness standards, not to mention drinking water standards.

What pollution does tap water carry in your home?

There is a lot of iron in city water, since the mains have been used for decades. Because of this, there are many insoluble suspended particles in water, such as rust, sand, scale, soil and sand. Water is treated with large doses of chlorine, which is very harmful to the body. In the pre-flood period, water is purified with enhanced doses of reagents, such as coagulants, flocculants, chlorine and ammonia. Since the water contains a high content of organics, bacteria and viruses.

How to maintain health, plumbing and household appliances?

All these factors negatively affect your body, plumbing and equipment. Today we buy and install expensive plumbing, faucets and hydroboxes to use high-quality equipment. Washing machines and dishwashers, as well as a boiler for receiving autonomously hot water at any time of the day, regardless of city networks. All this equipment also needs clean water to last a long time and justify its quality. We discussed these problems in detail and deeply in the article “HOW TO EXTEND THE SERVICE OF THE WASHING MACHINE, BOILER AND COOKWARE?”

Why is it necessary to install filter systems in an apartment?

What filter do you think to put in the apartment at the entrance? But first, let's see why it is needed. First of all, you get rid of fine trash that clogs nozzles in showers and hydroboxes. In the second place, you save water-heating equipment (heating elements) from scale (calcium and magnesium). Because the scale build-up on water heating elements increases electricity consumption by up to 30% and disables them over time. Soft and clean water saves the use of detergents 3 to 5 times and has a positive effect on the skin and hair.

What is the danger of water chlorination and high salt content?

By the way, chlorination of water in developed countries is recognized as a source of pollution, which leads to the formation of mutagenic and carcinogenic substances, toxins and has a delayed destructive effect on the human body. But, to do without chlorination is also impossible. Chlorine has a positive specific effect on bacteria and microorganisms. The thing is that it works effectively in troubled waters. And ultraviolet water sterilization technology, for example, which is also considered an effective but absolutely safe method, requires transparency so that UV rays can affect microorganisms.

There is sad experience when, in Peru, in 1991, the authorities decided to abandon chlorination, for the reason that it leads to cancer. This rash decision contributed to an outbreak of cholera. Therefore, it is not possible to abandon the use of chlorine, especially in our country. Since this will entail intestinal infections and a host of other problems. After all, pipelines are teeming with infection, so you have to choose between two evils. And it seems like the situation is at an impasse, but water filters solve all problems comprehensively and efficiently!

As for dissolved salts, the total content in the water supply systems of our country is on average 300 - 400 mg / liter. The drinking norm of salts is up to 150 mg / liter.

The first stage is the removal of solids and debris.

The first stage of purification removes insoluble (suspended) particles from water. Such filters are called mechanical. If the water consumption is not more than 15 m3 / month per month, a BigBlue20 type high-performance filter with a replaceable polypropylene cartridge is installed. The cartridge retains insoluble particles (suspended matter), such as soil, rust, sand, silt, scale, clay. The pore size of the cartridge varies from 20 to 5 microns. If in an individual case there is a lot of large debris in the water, then a wash filter with a 100 micron mesh is installed in front of the flask.

What mechanical filter to install with high water consumption?

In case when water consumption exceeds 20 m3 / month, it is recommended to install sedimentary filters of column type with an automatic control valve. This type of filtration saves your maintenance costs. Such filter systems contain filter media - Filter AG. This is a special charge that effectively removes suspended particles larger than 5 microns and organics.

Modern filtering materials save your costs!

Such a filter has a high filtration rate without pressure loss and has a long filter cycle. The filter surface of the AG loading surface is 1,000 times larger than that of quartz sand. Since the material is light enough, this reduces the water consumption during washing. The control valve is programmed for water consumption and the AG load is flushed with the back loosening method for the desired period. Replacement of filter material is carried out by our service department specialists. The replacement frequency is from 12 to 24 months, depending on the quality of the water and its flow rate.

The second stage is the removal of hardness salts, iron, organics, manganese and ammonium

Filter system with automatic control valve. The most popular downloads of Ecomix, Filtro Smart, Organic Multisorb, AquaMulti and other innovative materials are designed to remove a range of contaminants in the water. This type of filter media reduces water hardness and iron content, regardless of pH and mineral composition. This is a fresh development in the field of water purification technologies.

How does complex filter media work?

The download is made using a patented technology that is exclusive to the water treatment equipment market. During the filtering process, the load is distributed in layers in a predetermined proportion, as it has different weights and specifics. The components of the material are stratified in the desired sequence, which ensures maximum removal of impurities.

Restore working properties in automatic mode!

Regeneration (recovery) of the complex load is carried out with a solution of sodium chloride - sodium chloride. Such complex systems, as well as softeners, are equipped with a salt tank, where tableted salt is poured to regenerate the working material. In the Kiev region, water hardness is on average 4-6 units, so Filtro Smart and Ecomix-based filters are the optimal solution for both water from wells and the city main.

Your filter will do everything by itself!

The systems are also controlled by automatic control valves, which are individually programmable for water consumption and flow. When installing systems with multi-purpose loading on city water, the resource of the filter material increases and purifies the water deeper.

What are cabinet type filters?

For apartments, we recommend installing cabinet-type systems. In the “cabinets”, the salt tank is built into a common drawer along with the cylinder and control valve, this allows space-saving use and looks more aesthetically pleasing. Multifunctional loading changes every 3 to 5 years, depending on consumption and water quality.

The third stage is the removal of chlorine, chlorine compounds, organics, pesticides, petroleum products, humic and surfactants, color, taste and smell

Activated carbon from a coconut shell has a very high hardness of granules, which is 97%, it has a large surface area of \u200b\u200b1,000 m². It is distinguished by low ash content and the lowest content of water-soluble ash. Coconut coal is one and a half times higher than birch coal in terms of mechanical strength. The most common sorbent in the whole world.

Why install carbon filters?

The filter works on the same principle as the previous stage systems. The control valve is individually configured, depending on the consumption and quality of the water and is washed at the right time by loosening and dumping contaminants into the drainage. This is a necessary and final stage of cleaning in all filter systems, as it positively affects the organoleptic properties, and more precisely, the color, taste and smell of water. The filter load has a long service life due to the special hardness of the granules and varies from 12 to 24 months, depending on the consumption and quality of the source water.

A compact version of coal water treatment!

In apartments with low consumption, where the source water has already been partially purified by urban filtering systems, this system can be replaced with a Big Blue housing filter with a high-performance carbon cartridge. For this reason, you can go to the section "Main filters".

The fourth stage - ultraviolet disinfection of water (UF lamp)

Ultraviolet is an already ingrained technology and the best alternative to chlorine disinfection. Chlorine, as we know, is inherently poisonous. For example, in developed countries, chlorine is also used at the final stage in municipal water treatment plants, but in a ratio of 1: 1,000,000, in order to prevent the growth of microorganisms in pipelines. In the first stages of purification, ozone is used, which is an ideal natural disinfector, so there is no need to use chlorine in the amount that is used in our country.

What is ultraviolet radiation and what is its effectiveness?

Ultraviolet radiation is electromagnetic radiation with a wavelength shorter than visible light. Such lamps operate in the short wavelength range, which most effectively affect viruses, bacteria and microorganisms. This occurs at the DNA level and destroys microorganisms at the molecular level. At the same time, water does not lose its natural properties.

What is a UV disinfection unit?

For the manufacture of the case, stainless steel of grade 304 is used. Modern UF installations are equipped with an electronic controller that monitors the state of the working element and considers the use process. The controller is also equipped with a diode display, a countdown of work days and the amount of treated water. In the event of a malfunction or an expired service life, the integrated signal in the controller reports.

Which UV installation to choose?

UV installations are selected depending on the speed of selection and consumption of water. Our technologists recommend installing UF lamps as the final stage in the water treatment complex in those houses or apartments where parents are especially worried about the health of their children, since their immunity is more vulnerable than that of an adult.

Hard water with rust or dirt is the main enemy of modern household appliances. More than half of all breakdowns of heating elements are associated with bad water, therefore, special filters are used to protect washing machines and other expensive equipment.

Most machines have a coarse filter pre-installed, which traps hair, threads, buttons and other large debris, but cannot cope with small particles. That is why it is recommended to install an additional filter for the washing machine with bad rusty water.

First of all, it will help to eliminate mechanical impurities clogging the internal filter, which reduce pressure and, as a result, cause the machine to stop collecting water.

Water with rust and sand significantly reduces the duration of the pump for draining water. In addition, the quality of the washing noticeably deteriorates, because the dirtier the water, the worse the washing results.

Installing a filter, although an expensive, but quite economically feasible solution, since any breakdown of this equipment will result in significant repair costs.

Overview - types of water filters for washing machines

Manufacturers offer several filter options for washing machines.

1. Trunk. It is not installed specifically for the washing machine, but at the entrance to the apartment for pipes with hot and cold water. Thus, he purifies the water completely before it enters the apartment. Eliminates sand, impurities, rust, preserving its chemical composition.

2. Coarse water filter for washing machine. Mounted in front of the equipment to remove large particles. In most models, stationary ones are installed, they require regular washing and cleaning, as they quickly become clogged.

3. Polyphosphate. It is used to soften water. This is a flask with a filler - sodium polyphosphate, which does not allow molecules to form scale when heated. The device is easy to use and inexpensive. You just need to remember to fill up the filler. Only suitable for industrial water, since after cleaning with this device it becomes unfit for drinking.

4. Magnetic. Used similarly - for softening. It is mounted on the hose and affects the water with a magnetic field. The attitude of specialists to this device is rather skeptical, since there is no scientific evidence of its effectiveness.

Thus, the assortment of water filters for automatic washing machines is sufficient to select the appropriate one and install it to maintain the operability of the equipment.

Putting a water filter on the washing machine is easy and can be done without the help of specialists.

Trunk: installation is made after a tap that shuts off the water supply to the apartment. The pipe will have to be cut to mount the device.

Coarse filter: make a separate conclusion from the pipe with a tap, then mount the filter, then connect the washing machine.

Polyphosphate: installation is similar to a coarse filter. Before installation, read the manufacturer's instructions.

Magnetic: does not require interference in communication, is attached to the hose with a screwdriver and bolts.

Filter for washing machine to soften water - manufacturers rating

Among the manufacturers of filters for the protection of washing machines on the market, it is worth highlighting two models.

1. Geyser 1P. This is a main filter to remove impurities from cold water. It is installed on the pipeline with cold water at the entrance to the apartment. Protects from clogging, plaque and corrosion not only washing machines, but also water heaters, dishwashers, heating boilers and other equipment.

The device has a PP-series cartridge made of foamed polypropylene with a porosity of 5 μm. The cartridge cannot be restored; it must be replaced after contamination.

The housing can withstand up to 25-30 atmospheres, which is the best indicator among all modern filtering elements.

2. Aquaphor Styron. This prefilter deservedly takes the second position. It is used to protect equipment from scale, improves the effectiveness of detergents, reduces the need for their quantity.

The filling inside the device is designed for 300 washing cycles. The special chemical composition provides both water softening and corrosion prevention. It is used only for industrial water.

3. Of the polyphosphate devices, it is also worth noting the products of Geyser and Atlantic.

But before choosing the products of one or another manufacturer, it is recommended to conduct a water analysis and understand what its main "problems" are. Based on this, they select a filter device.

So, in the presence of rust, dirt and other impurities that precipitate, it is best to install a main filter at the entrance to the house. If this is not possible, then it is imperative to use a filter element immediately in front of the washing machine.

In most Russian regions, water is very hard, which means that you cannot do without a softener, for example, without a polyphosphate device. Those who believe in the miraculous properties of the magnetic option, you can try it.

VIDEO REVIEW

Experts believe that two filters will be ideal:

• to eliminate dirt, rust, litter and sand,
• to soften water.

Such protection will ensure the long and uninterrupted operation of your expensive equipment, regardless of the quality of the water in the water supply system or in the well, if the machine is used in a country house.

Based on the analysis of water, employees of specialized filter shops can help with the selection of the device.

Which water filter to put

Pure tasty water without impurities and odors often remains just the mistress's dream, while something chlorinated and neutralized flows from the water pipes. Of course, a way out can be a daily trip for water to a source somewhere outside the city in an ecologically clean zone, far from civilization. But if this option does not suit you, you should do it easier and buy a water purifying filter.

But what kind of water filter to put if in stores their choice is able to confuse not only in form and purpose, but also in the quality of the result of their activities?

Outdoor filter

If you live in your own house and use water from a well or a well, the first filter is best placed on the supply line to the house. Such a filter will save water from large foreign particles, without really changing its composition, taste and color.

In this case, it’s not worth it to pick and choose which water filter to install - take the one for which replacement cartridges are cheaper, since they are all about the same in quality.

Even better is to install two filters in a row: the first (coarse) will hold up larger particles, the second will hold small ones. Cartridges in such filters should be changed at least 1 time per month.

You can also put a rough water filter in the apartment if you are worried about the operability of a gas boiler or water heater, as well as household appliances such as a washing machine or dishwasher.

But it is necessary to install a filter directly at the tap in those cases if you use this water for drinking or cooking. Its task is to completely purify water from impurities harmful and dangerous for your body, reduce the content of salts (water hardness), reduce the amount of dissolved iron, improve the taste and dechlorinate (if water is supplied to your house or apartment centrally).

Choosing which water filter and where to put it, you can focus on the following tips from the masters:

• In the kitchen (under the sink), it is best to install a two- or three-stage filter (classic or with quick-detachable cartridges) with water outlet to a separate tap - when buying, focusing on the dimensions of the filter, ease of replacing the cartridges, their service life and cost.
• Before a dishwasher or washing machine, it is better to put a softening filter (for example, with polyphosphate filler).

• A shower cabin or a hot tub can be equipped with a filter based on ion-exchange technical resin (these filters do not create potable water, therefore they cannot be used in the kitchen).
• It is better to place a magnetic softener in front of the heating boiler or boiler.

• Directly in the shower, you can put a special filter nozzle (it will make water safer for the skin and hair by removing chlorine from it).

If you do not want to clutter up your water supply with additionally installed filters, you can limit yourself to a filter jug, which does not connect to the system, but is simply placed on the table. Water is poured into it manually.

Chemical water treatment

It is impossible to determine whether chemical treatment of the water flowing from your water tap is necessary by simply attaching it “by eye”.

It is better to send water for analysis to a specialized laboratory and only after receiving the results go to the store.

However, do not forget that filters, no matter how expensive or high-quality, will not turn water into “living” water by simply cleaning it from unnecessary substances. Unfortunately, modern filters cannot afford to repeat the composition of balanced spring water saturated with useful salts, sunlight and microorganisms.
