What to put a filter for cleaning tap water. Water purification system in the apartment: species and subtleties of choice. What company equipment is better to buy

Clean water without impurities enriched with minerals - a guarantee of good health and durability. In order for purified and the most useful water to be always in the house, it is recommended to install cleaning and filtering systems. Our rating of the best water purifiers 2019 will help you make a choice.

Water filtration began to practice at the dawn of the human era. One of the first methods of purification - coal filtration - reached the present day. The Russian market of cleansing technology is rich in the choice of filters of different systems, cleaning levels, sizes and appointments. The main classification is passed by type of cleaning:

• mechanical filters - multi-level cleaning systems that are used to protect plumbing and household appliances from scale and dirt.
• ion-exchange filters - systems for mitigating water rigidity, based on ion exchange resins. Filter not only iron, but also a manganese, with which most other systems do not cope.
• reverse osmosis filters are the most environmentally friendly and most effective systems. We cope with the removal of all impurities and bacteria, the water is additionally mineralized (optional).
• biological filters - the system works on the basis of microorganisms that purify water from organic pollution. It is used in aquariums and wastewater treatment plants.
• absorbent filters - the main cleansing component are absorbents, delaying impurities (the process of cable).
• aeration filters - water is cleaned with oxygen in special tanks.
• electric filters - purify water with ozone from all organic and inorganic pollution dissolved in it, however, are very uneconomical in power consumption.
• filters of a pitcher design - the design consists of a tank for crude water, a container for purified water and a coal filter.
• cartridge filters - the design consists of several flasks, inside of which the filter filler for each type of impurity.

Select water filter

The most important parameter for selecting the cleaning system is water purification. Allocate:

• single-stage cleaning level (elementary) - it includes a pitcher type filters. Clean only coarse pollution;
• two- and three-stage cleaning level (moderate) - filtered large and thin contaminants;
• the three-, four- and five-speed cleaning levels (high purification) - filters from all varieties of contaminants.

After you decide with the degree of cleaning, you should choose filter installation type:

• the filter with the crane is connected - a special nozzle for a crane, connecting directly to the output from the mixer, the productivity is only 0.3-0.5 l / min;
• a filter with a wash connection - the system "on the washing", is installed near the washing or washing, it connects to the tap mixer with a flexible hose, the productivity is average - 1-1.5 l / min;
• filter with a stationary connection for washing - the system "under the sink", according to users, one of the best water purification systems is installed under the sink, directly connects to the water supply system, has a second crane for purified water;
• a table dispenser - the quality of water purification is not inferior to the filter "under the sink", it does not connect to the water supply system, easy to maintain and harmoniously fits into the interior.

Let's summarize

Updated: August 2019

Water determines the very possibility of existence on our planet of all living things. Due to the presence of water, biochemical reactions in our organism flow at high speeds. The work of the body's protective forces, the rate of body reactions and the brain on external stimuli, the ability to survive in extreme situations, and generally survive are depends on this.

The rapid development of industry over the last two centuries was the cause of mass pollution of the environment by industrial waste, and rivers and lakes - the drains of the exhaust water water of industrial enterprises. Water has become dirty and unsuitable. Centralized water supply equipped with water treatment facilities is unable to clean water to acceptable condition. Fix the position will help the purchase of individual water purification devices. The editorial office of the "Yanashla" site offers to your attention the best trunk filters for water for 2019, an overview, compiled by customer reviews and recommendations of experts.

While our planet was so thickly populated, and the population was not engaged in industrial production, there was no need for a large-scale water purification. The problem appeared together with the formation of cities and the concentration in them a large number of residents. The first water began to clean the inhabitants of the ancient China. They impregnated with a wand coagulant - a substance capable of force solid particles in a liquid and fall into the precipitate. Then such a impregnated wand was stirred for drinking water. So it was possible to get rid of clay crowded. After that, certain flowers and herbs were added to the water, to give her a pleasant taste and smell.

The ancient Greeks purified water from impurities, passing it through several layers of fabric. Such a device was used in ancient medicine and was called "hippocrates sleeve."

The first to supply pure water in huge quantities carried out ancient Romans. They built aqueducts for which the water was signed in the eternal city. Mechanical impurities fell into the sediment in huge stone sumps. The construction was built by a hundred years and more and cost more money. Therefore, water from the aqueducts for the Romans was paid.

To disinfect in those days, double boiling was used. With the development of the industry and the accompanying urbanization began to appear treatment facilities, where large aquatic masses began to skip through the gravel backbone. Later, in the period of combating the cholera epidemic, the water began to chloride. However, chlorine is poison, as it turned out. Currently, scientists are looking for ways to combat bacteria in water without the use of chlorine.

What are individual filters

Filter Kuvshin

Filter jug \u200b\u200bis considered the cheapest and affordable. This simplest device is a small plastic container, divided into two parts: the bottom for filling with purified water, and an upper, equipped with a cassette filled with activated carbon. Granulated ion exchange resin, added to the coal aggregate, softens rigid water, large suspension is delayed in a fine grid. Some manufacturers are added to the content of silver, killing pathogenic microbes and bacteria.

Water is poured into the upper part of the jug, the complex processing passes and accumulates at the bottom of the device. The method is simple and efficient. At the output, the owner gets clean water suitable for drinking and cooking. Some models are equipped with an electronic indication that informs the user about the state of the cassette, or rather when it should be replaced. Such devices have their drawbacks:

1. remaining dry, the element loses its functionality;
2. an overdue cassette, saturated with harmful impurities becomes a source of pollution, so it is necessary to change it at least once a month;
3. the performance of such devices is extremely small and does not exceed 400 ml / min.

Important! The cost of the pitched filter is not large. If you do not know how much the cartridge is and how often it needs to be changed, it may seem that this is the most budget option. However, taking into account the monthly replacement of cassettes, such a type of devices becomes very expensive.

The jug is ideal for giving, where the user visits on weekends. In this case, two cassettes are quite enough. You can read about the best jug filters.

Filter - nozzle

A simple device is a cartridge that is put on the hussac of the mixer or crane. The device has small dimensions and can be useful in the country or travel. It can be put on a crane in the train, a hotel and take care of his health even in the "field conditions". It is worth considering that the nozzle will work effectively if the water has already been pre-clean. With serious pollution, the nozzle will not cope. In addition, the traveler will have to take care of the presence of a container where you can store purified water. The performance of the nozzle is as small. Devices inexpensive. The average cost varies within 130 - 3500 rubles.

Net filter

A simple device for removing suspended particles, scale and rust. It is a metal housing (better brass) with three holes: input, output, socket for installing a mesh cylinder. Machine diameter, with coupling and flange attachment. The cleaning element is a cylinder - a grid with cells of different size. The permeability of grids varies from 50 to 500 microns. The smaller the cell, the more the dirt will delay the device. From time to time the grid must be cleaned. For this purpose, a simple, mechanical method is applied:

• overlap water;
• unscrew the lid of the mud;
• remove and clean the grid;
• the assembly is made in the reverse order.

If you do the operation regularly, it is enough just to rinse the grid with water and install in place.

Cases are performed in two versions: with direct mud

and oblique mud.

Excellent device for coarse water purification.
There are options combining in one housing a mud with a ball valve.

Filters "under the sink"

The most common type of flow devices with interchangeable cartridges. A set of cleaning cassettes (usually - three) assembled into a single block is mounted under the kitchen sink. Connect to the water supply of the flexible sleeve. The outlet is connected to a separate crane mounted on a sink next to the mixer. The block includes cartridges for various purposes:

• propylene, produces mechanical cleaning from sand, rust and other mud existing in the pipeline;
• the ion-exchange resin of the second flask reduces the concentration of stiffery salts, i.e. Softens the rigid water, preventing the walls of the kettle, the saucepan, the heating elements of washing and dishwashers from the formation of scale;
• filling from activated carbon in the third cassette cleans water from free chlorine, organic impurities, heavy metals, eliminates unpleasant odors.

Model performance ranges limits 2 - 3 l / min. Depending on how much water is contaminated, cassettes can effectively process from 4,000 to 10,000 liters. Compared to the pitcher, the costs of consumables are less, cleaning is thinner and the device performance is greater. Perfectly proven itself as devices of thin cleaning of drinking water.

Main filters

Modern housing is unthinkable without household appliances consuming water in quantities that are significantly superior to the performance of models of type "under the sink" and, moreover, jugs. Washing machine machine, dishwasher or with a connection to the water supply, also need clean water. Otherwise, the owners are waiting for the serious costs of their constant repairs. The same applies to modern plumbing. A normal person needs to take a shower or bath. Rusty and dirty water is hardly suitable for daily hygienic procedures. The presence of free chlorine will bring harm at least than benefits. After all, chlorine is poison. Taking a hot shower, the user simply suits himself inhalation with chlorine couples, and this is the reason for many diseases. Main filters are designed to eliminate these problems.

Types of trunk filters

Unlike models "under the sink", the trunk devices are installed directly on the pipeline supplying water to all consumers in the apartment: plumbing, washing and dishwasher. They can be used as preliminary (coarse) cleaning devices before the devices "under the sink". In this case, the resource of the latter increases.

This type of flow device differs from the rest, above all, increased productivity. For the middle trunk device, this characteristic will range from 15 to 33 l / min. If this is not enough, the services of the device, with a capacity of 50 l / min, i.e. For an hour you will receive three tons of clean water.

Main models work with cartridges and without them. In the first case, the periodic replacement of consumables, two or three times a year is inevitable. This means that there are constant costs of buying consumables. The second option is a reverse flushing model. Here they use the cleansing elements made of stainless steel: grids or cylinders made of thin stainless wire, with a distance between the turns of 20.50, 100 microns. Water under pressure passes through the grid, leaving mechanical impurities from the outside. The flasks of such devices are equipped with a drainage crane at the bottom. To remove the accumulated dirt, it is enough to open a crane, pre-substituting the container under it, drain sucks and turn the crane again.

This process can be automated by mounting the valve with a controlled electric drive instead of a manual drainage crane and installing an electrocontact differential pressure gauge into the device cover, which allows the pressure difference at the input and output from the machine to determine its contamination. All devices are combined into the control power supply. Now on the signal from the pressure gauge, the valve will open, wash and the valve will be closed. The accumulated dirt along with water will go into the sewer along the flexible sleeve.

Equipment standards

There are two standards for the manufacture of cartridges and filters:

1. SL - Slim Line (Eng. Thin Line), European Standard;
2. BB - Big Blue (literally big blue, but the "blue abyss" is more interesting), the American standard.

SL Standard Equipment is more often used in the instruments of the "sink" type, or to clean the water at one parsing point. The reason is simple. SL Standard products are characterized by smaller sizes and performance. Therefore, to ensure a large water of a large apartment and the more suburban house, it will be more correct to use the instruments and consumables of the standard BB.

Polypropylene cartridges

The main purpose of the main filter is to protect against breakdowns of plumbing and household appliances. For this purpose, cartridges from foam polypropylene and polypropylene thread are used. They effectively clean the water from rust, the sand of the scale and garbage. The main technical characteristic of the polypropylene cassette is its porosity, measured in the ICM (micrometer or one millionth of the meter). Some products are released with porosity 5 and even 1 microns. This means that they will not pass through themselves particles larger than 5 or 1 microns. At the exit, we will get water with almost no mechanical impurities: dirt, sand, rust, etc. Manufacturers are introduced into a polypropylene aggregate ion exchange resin for softening rigid water, or silver ions to destroy malicious bacteria. The resource, or the time of efficient operation of the polypropylene aggregate directly depends on its porosity. The more dirt stops the product, or the less his porosity, the less its resource.

Important! It should be understood that the polypropylene cartridge removes only mechanical impurities from the water: dirt, sand, rust. Cleans water from organic impurities, iron or chlorine it is unable.

Coal cartridges

It is used to lighten water and remove organic impurities from it, free chlorine, unpleasant odors. They are made in the form of a container filled with a powder of activated carbon or sintered activated carbon. The material for the manufacture of activated carbon serves the coconut shell calcined at high temperatures.

Cartridges to reduce the concentration in water water

Another major water user problem is an increased iron content. It is iron that leaves the redhead on the faience of plumbing, spoils with a washing snow-white underwear. To reduce its concentration, cassettes are used with the function of debitabilities made of special threads, with impregnation of ion exchange resin. A second option can be a container filled with a catalytic material, on the surface of which the iron oxidation occurs and its delay outside the element occurs.

Softening cartridges

For rigid water, characterized by elevated content of calcium salts, potassium, sodium and magnesium. They are the reason for the formation of plaque on the walls and the bottom of the teapots, the heating elements of washing and dishwashers that reduce their efficiency and sharply limiting the working resource. To reduce the concentration of stiffery salts, special containers filled with ion exchange resin are used.

Important! There are containers with filling from polyphosphate. They will not give the formation of a raid on the surface of the heating elements, but the rigidity will remain the same.

Reverse osmosis

Excellent cope with water softening devices with reverse osmosis function. The principle of operation is simple. The flask is separated vertically into two parts of a special membrane transmitting water and delaying solid solid solids in it. Water is pushed through the membrane into the "clean" half of the flasks, and the salts remain in the "saline" part. However, it should be understood that the softening of water, "to zero" is not good. Salts calcium, potassium, sodium and magnesium are needed by the human body in certain quantities and are easiest that they are absorbed with water. So, after softening, it will have to add a device with a mineralization function to the filter complex with mineralization, passing through which, water is again saturated with salts. True, now in the regulatory amount.

It makes no sense in such a softening. It is widely used in industry, where desalted water with reduced electrical conductivity is used. In this case, the management of the enterprise will have to organize the cleaning of saline drains, not to fall under the sanctions of environmental departments.

In order to eliminate all water problems, you can set two or three main instruments with fillers of various purposes. Some manufacturers produce a device with several enclosures for this purpose.

To pick up the optimal set of cleansing devices, it is necessary to pass water to the analysis of the chemical composition in the nearest SanEpidemstan. Having received it, you need to refer to the specialists and listen to their advice. They will prompt how to choose the most suitable cartridges for your water.

What company equipment is better to buy

The popularity of models depends on many of its characteristics: prices, quality, functional, performance. The buyer assesses how developed by the network of service centers, is it easy to find consumables for a particular model. For example, the Russian company Aquaphore Viking has developed cleansing cartridges for its devices according to its own standards, ignoring the prevalence and popularity of consumables according to SL and BB standards. Now her buyer is forced to look for branded consumables. For the company it is good, and the client is limited in choosing. Nevertheless, Aquaphor's products are successful in domestic buyers, for ease of installation and operation, high-quality materials, good performance.

The same can be said about other Russian manufacturers: "Geyser", "Barrier", "New Water". One of the best manufacturers of this type of equipment is the Russian company "FIBOS". Her model of Fibos Fibos is well deservedly popular 3. Excellent reviews are left buyers about Honeywell products from Germany.

Criteria for selecting the main filter

1. Selecting the model prefer devices with a drainage crane. The ability to reset the pressure in the flask when replacing the cleaning element will get rid of unnecessary troubles.
2. Find the popular models of well-known manufacturers. Listen to the recommendations of the experienced users, decide on the price, find out from the seller, are there problems with the purchase of consumables.
3. The transparent case makes it possible to visually observe the degree of its clogging and timely clean the grid or replace the cartridge.
4. Models with plastic enclosures are well on cold water. Experienced users do not advise plastic on hot water, even if the manufacturer guarantees its operation at a temperature of the working medium to 100 ° C. Sooner or later you will get a flood.
5. Choosing a model with a metal case and without having to visually observe how the device is clogged, stop your device on the device equipped with the inlet and outlet pressure gauges, or models with a differential pressure gauge. This will allow you to rely on the pressure drop (difference) of the pressure, determine the change in the cartridge or grid cleaning.
6. If you are looking for a model in a private house, stop your choice on a device with a lot of performance, not lower than 30 l / min, and the porosity of the cartridge is not more than 20 microns. Water from wells is always distinguished by significant pollution and save on the subtleties is not worth it. It is desirable to establish several trunk devices with different filling, based on the chemical analysis data.

What should pay attention to

1. Buying a product Check out the package. Make sure the kit has a special key to unscrew the flask. During operation, try not to lose it. The key from another model is uniquely not suitable, and if the flask "presses" to the lid, you will not be able to remove it.
2. Carefully read the description, especially the installation instructions. If you do not know how to install a trunk filter, refer to the specialists. Throwing the thread in the lid of the case is easy, especially if it is plastic. It is very difficult to correct this and the danger to flood the apartment grows at times.

Water is life. Clean water is a long life without disease and ailments. You have a chance to access clean water.

Buying a device capable of cleaning the water from all the ugly impurities, you get rid of the need to spend money on your treatment, repair or replacing the washing and dishwasher, mixers in the bathroom and in the kitchen. Lunch, cooked on clean, without other odors, water will take you true pleasure. Invest in your health. Think as it should and buy a good trunk water filter. Our site will help you not make mistakes when choosing a better model.

Water that enters our homes and apartments in city communications or from autonomous sources is almost always far from perfection and requires a certain preparation, especially for nutritional use. It can be contaminated with solid weigon, to contain an unacceptably high concentration of various salts and other chemical compounds, differ in increased rigidity, and in addition, the biological infection is also not excluded. Even if diverse, complex water treatment is carried out at the urban cleaning stations, when moving along the old pipelines, water may have so much to pollue again, which falls to the tenants of apartments already in a completely unsuitable for food consumption. Buy for these purposes bottled - it seems to have a way out, but it is inconvenient, and quite expensive. It is better to establish an effective home filtering system so that there is always unimpeded access to clean, safe water.

The owners of private houses in this matter are somewhat simpler - the presence of utility premises allows you to mount a multi-level cleaning system, especially since using the autonomous source of water without this can not do anyway. And how to be residents of standard apartments, who have every centimeter of useful space? There is a solution - on almost every kitchen, a free niche remains under the sink, in which there is a trash can, or an empty glass container is simply accumulated. What is not a place for the drinking water cleaning system? But this is how to choose the sink to sink and forever solve the problem? Let's try to figure out the diversity of such cleaning systems.

The fundamental device of filters under the sink

What are the filters for the sink differ from their other "fellow"?

As a rule, this console design is compact enough to fit in space under kitchen sink.

The console itself (pos. 1) is a kind of "assembly site" on which all the elements of the filtering system are mounted. Most often it is performed in the suspended version, for mounting to the wall (wall of the kitchen cabinet), although there are options with the installation on a horizontal surface. In addition, there are models of cabinet filters.

The console is installed filtration modules (pos. 2) of various purposes. Water passes through them sequentially, exposed to one or another type of filtering and cleaning. Filtration modules can be a flask from themselves to install replaceable cartridges (pos. 3), but there are indispensable modules. The number of modules may vary - from one in the simplest filters up to five and even more in high-tech water purification systems.

flowing filter

In addition to filtering modules, the system can be equipped with a waterproof water treatment unit (pos. 4) and other water treatment devices.

Any filter complex has a fitting with a fitting for connecting to the water supply (pos. 5), and the output (pos. 6) - for feeding purified water to the crane. In reverse osmosis systems, it is usually still provided for a nozzle to relieve dirty water into drainage (sewage). To connect the kit includes flexible hoses (pos. 7), a crane with a tee for the insertion into the water supply (pos. 8). As a rule, in the set there is a crane for the fence of a clean ox (pos. 9), which is installed on the kitchen sink next to the mixer.

The key (pos. 10) is used to unscrew the filtering modules if you need to replace them and for reverse installation.

Filtering stations with installation under the sink can not only be a flow, but also the accumulative principle of operation. In this case, the kit includes a membrane hydroaccumulator, in which water purified under pressure is accumulated. Conveniently, from the point of view that at the disposal of the owners there is always a certain margin, and even if the feed is stopped for any reason.

For some models of filters under the sink, especially with a reverse module or with a cumulative reservoir, an increased pressure in the water supply system is required. To ensure these conditions, the installation can be equipped with a built-in pump, which, in turn, will require connection to the power supply network.

A variety of models and a wide range or replaceable cartridges to them allow you to choose a water purification system that is optimally suitable for existing conditions. However, in order not to make a mistake with the choice, first of all it is necessary to figure out how the steps of water purification work.

The main steps of cleaning drinking water

Depending on the degree of contamination of the incoming water, it can be subjected to different cleaning stages.

• First of all, water must complete mechanical filtering, that is, to free themselves from suspension, solid particles. They not only reduce the taste and organoleptic water quality, but also quickly clog other cleaning modules.

Mechanical cleaning cartridges work on the principle of conventional filtration - water passes through minor pores, and solid suspensions are delayed. The filtering elements themselves may have a mesh design, or be made of polypropylene - foamed, nonwoven corrugated, or wounded in the form of "ropes". The degree of cleaning in such cartridges can reach 5 microns. However, neither dissolved in water substances nor the majority of microorganisms are delayed by similar filters. This module can be safely attributed to the turn of preliminary preparation for further cleaning.

• A lot of problems can create a large content of dissolved iron in water. This, useful, in principle, for human health, an element at its high concentration becomes the "beach" of tap water. Not only are these problems of "household" character - an unpleasant, metal taste, rusty water color, red spots on wrapped clothes, etc. Molted iron can cause poisoning and even lead to the emergence and development of systemic diseases.

Iron in water may be contained in the form of a free dissolved element (bivalent iron), and it is not amenable to no mechanical filtering. It is practically not delayed by any filters organic colloidal iron - weighted particles are so small that they pass through the pores. But already hydroxide is a solid precipitate, as well as the trivalent iron - it is its us as we see in the form of a rusty finely dispersed plaque on the dishes, in washing, etc. And such forms can already be separated by defending and filtering.

There are several ways to combat the high content of iron, but they all reduce the activation of its reaction with oxygen contained in water or applied by artificial path (aeration). As a result of oxidation, colloid or dissolved iron passes into insoluble forms, which are already removed by filtration. Of all the technologies on the household level, only a non-negotiable is used in home compact filters. In cartridges (modules) there is a special beeping of mineral (dolomite, zeolite, etc.) or synthetic ("inIRM", "MZHF", "Pyrolox") of origin, which in itself without entering the reaction, plays the role of a powerful catalyst that provides a full oxidative process.

As a result of the reaction, the fine insoluble suspension remains in a backfill or in the mesh filter embedded in the cartridge, or is completely removed on the following purification steps - in the sorption module.

• The next problem of water is the so-called stiffness. Such a phenomenon is due to the increased content of calcium and magnesium salts. Hard water is unpleasant to drinking and cooking, as it has a bitter taste, it quickly overwhelms the characteristic scan of dishes, it is poorly dissolved and deteriorating and ineffectively apply detergents and erasing compositions.

The main method of softening water for nutritional needs is the use of ion exchange resins. The principle of operation lies in the fact that during the passage of rigid water through such a backfill in the solts of rigidity, magnesium or calcium molecules on a more active metal - sodium occurs in a natural way. And sodium salts have no longer affect the quality of drinking water.

The technology of such purification from salt salts involves the possibility of regeneration of ion exchange backfills. However, in compact filtering installations, cartridges are usually applied, not subject to recovery. With a large degree of water hardness, such items will have to be changed too often. Therefore, with very hard water, it is rational to use the reverse osmosis system, which will be described slightly below.

• In tap water, the presence of chlorine is very often obviously felt. A mixture of dissolved hydrogen sulfide is not excluded, with a characteristic pendant smell. Often there are certain concentrations of petroleum products, salts of heavy metals, various organic compounds. All this leads to a deterioration in the food quality of water, and may also be a serious threat to the health of people.

Decide these problems filters with sorption fiber. Most often is activated carbon or special minerals that are able to derive harmful chemical components from the water. In addition, such fillers become a catalyst for oxidative processes and at the same time serve as a mechanical filter holding solid precipitation resulting as a result.

The variety of sorption modules is very large. In some of them, the composition may be born with a "accent" on one or another lack of water, for example, on the increased content of free chlorine or, on the contrary, dissolved organics. Cartridges are produced, the sorption filing of which, in addition, does not leave almost no chance of pathogenic microorganisms - water passes and biological cleaning.

• The highest indicators of water purification by all possible contaminants have modules operating on the principle of reverse osmosis.

The essence of their work is that water under a certain pressure is literally praised through a membrane having a pores measured by hundredths and thousandths of the micron. The membrane is usually executed in the form of a spiral-laced roll (pos. 2), which gives a large working area.

As a result, the flow (pos. 1) is divided into two - permeate (pos. 3), that is, purified water, which passed through the membrane, and concentrate (pos. 4), in which all impurities removed from the permeate remain. Purified water goes to the consumer, and the concentrate is reset into the drainage system (sewage).

The table below, the table is eloquently indicates how deep cleaning the water is obtained in the reverse osmosis module

The reverse osmosis membranes of organic compounds molecules are missing. They are delayed, in addition, many bacteria and even viruses. In a word, water is obtained at the exit, close to its qualities to distilled.

water filter

• Water that has passed the reverse osmotic purification, not everyone comes to taste due to the almost complete absence of mineral salts. There are rumors that it is even harmful to people's health, but this is only insinuations - the whole necessary supply of trace elements is a person gets from food. But to fix the taste of the quality of drinking water will help special mineralizers modules that are installed after the reverse osmosis block.

For the rational use of the resource of mineralized blocks on some models of filtering stations with installation under the sink, two contour of the pollocks of water for consumption is provided - ordinary, without mineralization. For cooking, and after mineralization - for drinking purposes.

• For apologists of almost complete sterility of water at the exit, filtering stations are produced under the sink with a ultraviolet irradiation module.

Ultraviolet rays kill almost all known pathogenic bacteria. True, such a filter will require connection to the power supply network.

There are also other modules of varying degrees of preliminary and post-cleaning, as well as those who give the resulting water any special qualities, for example, saturately by silver ions.

How can you make sure this modular scheme is characterized by very high flexibility. Consumers are provided with an excellent opportunity to choose the necessary model and a set of cartridges to it, based on the actual conditions, making, if necessary, emphasis on a particular cleaning level. But for this you need to be able to make a choice.

How to choose a filtering station under the sink

The selection of the system should be started with accurate clarification of the source conditions. It is necessary to have information about the characteristics of the water supplied to the apartment or the house to determine the necessary methods of cleaning it.

The main condition is to have information about the quality of the incoming water.

It is no secret that the cases have recently become frequent when the commerivaires go through apartments show the trustful owners of various "colorful experiments", convincing them in the terrifying quality of water and imposing the purchase of expensive equipment. Not always it turns out to be so necessary. It is better to take care of the quality of your water source.

For this, the best option is to pass the water sample to a laboratory study. Moreover, the analysis should not trust employees of companies engaged in the implementation and installation of filters - the party is obviously interested, and can attribute what is really not. It will be unreasonable to conduct research in the laboratories of water-supplying organizations, as it can be a completely opposite picture here, that is, the concealment of certain flaws. The optimal option is a sanitary and epidemiological service or independent laboratories. This is true, it is somewhat more expensive, but it guarantees the impassiveness of the tests.

By the way, the proper result of a laboratory study is a legal document. It will not only help correctly, but also can be the basis for presenting claims to utilities in terms of non-compliance with the required sanitary standards.

To put water to the study, it is necessary to correctly complete the sample.

If water is only surrendered for chemical analysis, the sample is typed as follows:

• For analysis, 1.5 liters of water will be required. It is best to take an empty clean bottle from under drinking non-carbonated water. It is forbidden to use the empty container from sweet drinks or beers.
• Opens a crane, and is left for at least 15 minutes for free water outlet.
• After that, the bottle itself and the cover to it is carefully rushed by this running water, without the use of any detergent.
• Then the water pressure is reduced to a minimum so that the appearance of a set of air bubbles is not caused, the bottle is filled with the top, with overflow, and immediately closed tightly with a lid.

For biochemical analysis, the requirement of several other, tougher, and most often the laboratory workers give a disposable sterile container to sterile sterile, instructing the rules to fill it.

It is not necessary to simplify the task, acquiring in the store a set for express testing of water and limited to it. It is, of course, easier and cheaper, but the informativeness of such mini-studies is low. The results undoubtedly sign out about the presence of one or another problem in the chemical composition of water, but will not show its real level.

Now, with water tests in your arms, it will be possible to talk to an equal footing with the company's specialists implementing filtering installations. So you can avoid two extremes - the acquisition of a filter that will not cope with the task of full-fledged water purification, or buying an expensive station, the possibilities of which will simply remain unclaimed.

Criteria for selecting a filter under the sink

So, if with the necessary steps of cleaning, their number and target destination. Clarity appeared, it is necessary to evaluate the selected filtering station and for other criteria.

• Dimensions and the ability to install in the existing space under the sink.

The filtering station will be hidden from sight, so the issues of its external design should not act as prevailing. But dimensions, on the contrary, are crucial - how to make sure when viewing above the illustrations above, the size of the design can differ significantly.

We should not forget that it is necessary for a certain space under filters - to ensure the possibility of replacing cartridges. True, some modern models have an interesting hinge mount of the modules that make it possible to simplify this process.

Another nuance is the entire filtering installation, and even with the flasks completely filled with water, it can weigh a very much. It means that you should think about a reliable basis in advance for its suspension or outdoor installation.

The installed filter should not prevent the closure of the cabinet door under the sink. In addition, access to plumbing communications should be provided.

• System performance

This question is usually too acute. For drinking purposes and for cooking, there will be enough indicators of 1.5 ÷ 2 liters per minute, and most of the filtering modules fully supports such a consumption. Yes, and the design of the selected crane for drinking water is designed for similar performance.

True, you can meet models that provide for a branch to the kitchen mixer - after mechanical filtering modules. Thus, water, for example, for washing the dishes also passes a specific cleaning cycle, but for food purposes is subjected to deeper processing.

When evaluating the performance of the entire filtering unit, of course, the bandwidth of the module with the most minimal performance indicators should be taken into account.

• Resource modules and cartridges

This question is always one of those who are interested in the first place. Indeed, how often have to acquire replaceable filtering elements?

The question is ambiguous, since any cartridge may have its own capabilities, but they are necessarily indicated in the accompanying documentation. As a rule, the resource is measured by a total volume of water transmitted through a replaceable element, for example, 4000 liters (4 m³). In the family (and it is usually about 3-4 liters per person), it is easy to estimate that for a family of 4 people at a cost of 15 liters per day such a cartridge is enough for about 267 days.

At the same time, you can not forget about one nuance. The fact is that, besides the volume of water, the resource is also expressed in time. For example, it is indicated that the cartridge is designed for 4000 liters, but not more than 6 months of operation. It means that even if much less water was missed through it, which is indicated, still six months later it is subject to replacement.

By the way, the various cartridges of the same filter complex can have their own, irradiated parameters of the laid resource, and the shift will have to be changed in such a case as it is developed or expiration.

Some cartridges, for example, ion exchange, are subject to regeneration - this should also be reflected in their passport.

The resource of the cartridge may decrease if the water comes in highly polluted. Anyway. If the deviations are noticeable in taste and in the smell of purified water - this is the signal to replace the elements.

Has its own resource and membrane of the reverse osmosis module. True, usually the duration of its service is already measured in several years.

The condition of cartridges and the timeliness of their replacement must be monitored. Some firms are practicing an SMS or E-Mail distribution of reminders about the need to purchase interchangeable elements. It should always be remembered that it has served, but not replaced in time the cartridge is able to bring more harm, rather than use.

flowing filter

• Features of selecting a filter with a refundable module

If it is decided to purchase a filter under the jacket with a reverse osmosis module, then another number of nuances should be taken into account:

- This setting necessarily requires a certain pressure supplied to water purification - this parameter is defined in the technical documentation. If the local pressure of the pressure does not reach the desired level, or the usual phenomenon is a drop in pipes in pipes (for example, in a multi-storey building), then it is necessary to look for some solution.

You can purchase a filter installation, in the layout of which enters the built-in pump. Another option is to install equipment for the overall increase in pressure in the local apartment water wiring.

How to raise the head in a home or apartment water supply?

There are several acceptable solutions. One of them is an installation. This is more detailed in a special publication of our portal.

- If a pump and (or) module of ultraviolet water treatment is enabled into the cleaning system, then you need to think over the supply line of the power line and install the outlet. The socket must be moisture-proof, and placed in such a way as to exclude a random falling on it. But in any case, the extension can pull to the place of installation of filters - this is not the best solution.

- You should immediately think about the question, whether the accumulating tank is needed, or there is enough flow system. This largely depends on the stability of the pressure in the plumbing. If the output interruptions are not rare, then it should be wiser to purchase a filter with a cumulative tank. At the same time, do not forget that the tank also requires space in sometimes a fairly close opening under the sink.

- The question of performance for filters with a reverse osmosis module is somewhat ambiguous. The fact is that practice shows: in order to get one liter of high-quality purified water, the order of two liters will have to be discarded into the sewer. People who are accustomed to save on everything, it is also worth thinking about it too.

By purchasing any filter model under the sink, it is necessary to carefully check the delivery package, so that it is not necessary to experience difficulties with the installation of equipment. Be sure to conduct a scrupulous visual inspection for damage to the console, the flask filtering modules. Special attention - nodes of compounds, fittings and hoses, the presence of necessary sealing or sealing parts.

A brief overview of filter models with a cleaning unit

Despite a very wide range of filter installations of this type, the choice still should be done in favor of manufacturers who have earned considerable authority in this particular field of activity. As such can be attributed "Atoll", "Geyser", "Barrier", "Aquaphor", "Aquapro", "Raifil", "New Water", "Aquafilter", "Aqualine", "Zepter", "Ecosoft".

Probably, it should once again remind potential buyers that it is necessary to acquire water purification equipment exclusively in specialized, proven outlets, and even better - in representative offices of manufacturing companies. The "wild" market is sisite with low-grade fakes, and risk the health of your family, in the hope of saving - this is the top of the recklessness. When buying, be sure to set up the stamp in the passport to obtain a warranty.

1. The capacity of the prefilters facing the main membrane (in micrometers - microns).
2. The presence of mineralization function.
3. The quality of the materials of the manufacture of filter elements.
4. Cost of equipment.
5. Manufacturer.

Which filter with reverse osmosis is best suited for specific conditions, solves the buyer. Our task is the selection of the best models based on user reviews, familiarizing readers with the proposals of the modern market.

The filter under the sink is one of the most useful kitchen devices. It not only cleans the water from all sorts of impurities and harmful substances, but also simplifies the process of its preparation. Through an additional crane that is mounted in a kitchen sink, it is possible to get clean water short, without spending time and money for the purchase of bottled water or pouring water into the filter-jug every time.

You can see many different systems on sale, but not all of them cope with the task of high-quality purification of water. To choose a truly good filter, we recommend that you familiarize yourself with our rating.

The best inexpensive water filters for washing: budget up to 5,000 rubles.

Cheap filters under the sink are on average 1,500 - 5 000 r. They rarely meet membrane filtering, softening and mineralization, and the number of cleaning steps does not exceed three. At the same time, most models are quite capable of saving water from heavy metals, chlorine, phenol, benzene and other chemical additives.

Another advantages of this filter include the presence of a filter for water softening. This will make rid of scale in the kettle. True, there are complaints about the fact that this filter is quickly clogged and after a couple of months it appears again. This is your explanation - in areas with very rigid water, the filter for obvious reasons will be clogged much faster. You just need to change the cartridge on time.

Edward's review of Edward:

If you take this filter, then immediately buy a drill on 12, otherwise go again to the store to make a hole in the tabletop. Everything else is included, only self-tapping screws for fastening to chipboard are short. In general, the filter is like, recruits a little more liter of water in a minute. This, by the way, confuses, is filtering too quickly. Maybe it affects quality?

Best filter systems for washing with reverse osmosis (membrane)

Membrane filtering is considered better, since the exit is almost perfect water purity. The pores of the osmotic membrane are very small and delay most of the pollution, iron, petroleum products, and so on. It is important to notice - the membrane is very dense and for passing through her water requires good pressure. If the pressure in the water supply system is small - the filtration rate will be extremely low. In such cases, it is recommended to pay attention to models with an integrated pump to increase pressure.

3 Geyser Prestige P

Built-in pressure pump
Country Russia
The average price: 11 900 rubles.
Rating (2019): 4.6

This filter system is recommended to buy this filter system, if you have a bad water pressure in the apartment / house. "Geyser Prestige P" One of the few models that is completed with a pump to increase water pressure. This will allow to start the filtering process even in places with extremely low pressure (for the operation of the reverse osmosis requires at least 2 atmospheres, otherwise the system will not work).

Otherwise, in Geyser Prestige n, there is all that and competitors: 5 papers of cleaning, imbeling, softening, reverse osmosis, accumulative capacity by 12 liters. It is a pity, of course, that there is no mineralizer of water, because for about the same money from a competitor atoll a-550m STD, the mineralization function is present.

From positive feedback, users note high quality filtering, not expensive and very affordable cartridges (except membrane for 2000 p.) And moderate drainage (0.3 liters per 1 liter of clean water).

2 Aquaphor OSMO 50

Best price. 5 Cleaning Stages
Country Russia
The average price: 7,490 rubles.
Rating (2019): 4.8

AKVAFOR OSMO 50 is one of the most affordable prices of filtering systems with reverse osmosis. In addition to the membrane, there are 5 water purification steps, a cumulative capacity of 10 liters and softening functions and purification from dissolved iron. In principle, this is enough to obtain high-quality water, as evidenced by user feedback. Water becomes better taste, disappears and smells.

There is a truth substantial minus characteristic of a variety of models with reverse osmosis - high side consumption of water in drainage. For one liter of pure water in drainage takes at least 6 liters. If for the month you consume 300 liters of water, then at least 1,800 liters (almost two cubic meters) go into the sewer. For owners of houses with private sewer, such pleasure will fall out in the "penter".

Also, do not forget about the cost of replacing the filter elements. Depending on the intensity of use on the replacement of filters, Aquaphor OSMO 50 may leave 1500 - 5500 p. in year.

1 atoll A-550M STD

Mineralization function. Price quality
Country Russia
The average price: 11 400 rubles.
Rating (2019): 4.9

The rating of the best filter systems with reverse osmosis entered the ATOLL A-550M STD model. This is the most expensive filter system from the review. But the price is justified. ATOLL A-550M STD is completed with two very useful elements: a mineralizer and oxygen enrichment feature. What is the benefit of this? As described at the beginning of the article, the membrane makes water crystal clear, sulfice both harmful and useful for the human body (minerals). Water is almost like distilled, which is not good. So, in Atoll A-550M STD after all cleaning procedures (and there are 5 steps here), water is additionally enriched with mineral elements. And water becomes much more useful than after the usual purification by reverse osmosis (membrane).

From other useful functions atoll a-550m, you can select the device for the dearness of water (removal of dissolved iron) - it will be useful for residents of districts with very hard water. Also, the filter system is equipped with a very roomy 12 liter tank-drive, which will be more than enough to ensure clean water for 2 - 6 people.

As for feedback, mostly they are only positive. Users praise atoll a-550m primarily for very high-quality filtering - water becomes really tastier. Of the not very pleasant moments you can highlight sufficiently expensive cartridges. There are enough for a long time, but after 2-3 years (depending on the intensity of use) you will have to lay out for the cartridges almost as much as the entire system costs. ATOLL A-550M STD - the best value for money!

How to choose a filter system under the sink?

Before choosing a specific cleaning system, it is not bad to have information about the chemical composition of water, which flows from under the tap. This will allow you to pick up that filter that will deterioably clean the water. So, if you have very rigid water in the apartment, you will have to take a more expensive filter with a membrane (reverse osmosis). Cleaning very hard water is obligatory if there are people in the family with a kidney disease. For less rigid water, a budget filter with ion exchange can be enough.

You can find the chemical composition of water in different ways. For example, ask the local vodokanla or hold your own "mini laboratory study." Water rigidity can be found using a special test strip, and the chlorine content helps to determine the iodocharmal paper (can be purchased in the stores selling aquariums).

When buying a filter under the sink, in addition to the price, it is necessary to look into two important components: methods of cleaning and the presence of water softener. The methods of cleaning water in each system under the sink can be several and their quantity and quality directly depends on the cost of the entire system.

Membrane filtering

For example, in budget filters up to 3000 p. As a rule, there is no membrane filtering. Membrane filtration (ultrafiltration, reverse osmosis) serves to perfect water purification from viruses and bacteria. Only very thin particles of water pass through the membrane (up to 0.0005 μm), and all other impurities and bacteria are delayed. At the exit, very clean water is obtained, almost like distilled. But the membrane has a significant minus - together with bacteria, useful minerals are filtered. Therefore, there will be no harm or benefit from such water. Solve this problem will help buy a filtering system with a membrane and built-in mineralizer. Thus, the water completely purified from metal ions will be rejected by minerals.

Ion exchange

To clean the rigid water from heavy metal ions in budget filtering systems, only ion exchange is applied. So high quality clean the water, as it makes the reverse osmosis, the ion exchange will not work, but still it is better than nothing.

Coal filtration

Coal filtration is a very useful feature that is present in most filter models. Coal is used to absorb chlorine, phenol, benzene, toluene, petroleum products and pesticides. It clears from all that is added to the water for disinfection. Even budget systems under the sink have coal filtration, but still in some models it may not be.

Softening water

Water softening is an extremely useful feature of the filtering system. With it, it is possible to reduce the content of calcium and magnesium ions in the water, which stimulates the formation of scale in kettle, dishwasher and washing machine. This will not only save a housewife from unnecessary trouble with the removal of scale, but also will significantly extend the life of kitchen appliances.
