Filter for tap water. Apartment water purification systems

The initial stage of choosing a filter is to become familiar with all types of devices available on the market. There are only two of them; they are very similar in appearance, however, they differ radically in content and operating technology.

Household filters for purifying tap water are of the following types:

• equipped with a flow-type filtration system;
• using the reverse osmosis function.

The answer to the question: which water filter is better depends on the initial quality of the water. Next, the characteristics and differences of each of them are presented in detail.

Flow type

Such a filter consists of three or four modules, which are connected to each other in order (series). The first stage is rough purification of tap water, followed by the main stage of purification, and at the end – final purification. Since the device uses several different filters based on different cleaning methods (mechanical, using sorbent, with silver), the water flowing out of it is of high quality.

First, large particles of dirt and rust are removed from tap water. At the next stages, the liquid is disinfected and unpleasant odors are removed from it (for example, the smell of chlorine). This option is the best choice if the water contains heavy metal salts, residual oil products, and even pesticides. Choosing a flow-through option is the answer to the question: which water filters for sinks are better?

The modules that make up the filter may differ in content and functions:

• for rough, mechanical cleaning;
• universal, used for water of medium degree of contamination, without a high content of impurities;
• aimed at softening too hard water;
• for liquids with a high content of salts of heavy metals and metals themselves;
• with an antibacterial effect, providing maximum protection against viruses, bacteria and cysts.

Before purchasing, you should decide which household water filters for sinks will best cope with water purification in a particular case. The flow filter has one significant disadvantage - if the water is very hard, you will have to change the filter modules frequently. This will affect the cost of servicing the device; it will increase significantly.

Using a reverse osmosis system

Externally, such filters are very similar to the previous version, however, their operating technologies differ significantly. From one (in budget versions) to five (in premium models) cartridges are mounted on a single plate. Each of them is a plastic flask, inside of which there is a filter element for different purposes. The main difference is the mandatory presence of a cartridge with a reverse osmosis membrane; passing through it, the water undergoes ultrafine purification.

Types of modules included in the reverse osmosis filter:

• for mechanical purification from large impurities and inclusions;
• with carbon sorbent inside. This cartridge removes organic contaminants, oil refining residues, heavy metal salts, unpleasant odors and tastes from liquids;
• removing excess iron content. Their “filling” consists of active substances that react with the iron in the water and completely neutralize it.

At the beginning of the system there is a coarse filter, then cartridges with other filling and, at the very end, a reverse osmosis cartridge. This membrane allows water to pass through while retaining all other contaminants. This is reverse osmosis. For the entire device to operate, the minimum water pressure in the water supply must be observed, usually 3 - 3.5 bar. Often, an electric pump is included with the filter to create the necessary pressure. There are models on the market that are equipped with an ultraviolet lamp. It disinfects and kills all pathogenic microorganisms.

Almost distilled water flows out of the reverse osmosis filter. Many manufacturers complete the device with a mineralizer, thereby replenishing the missing elements and microelements. Another feature of this type is the presence of a storage tank. Since the cleaning procedure is slow, it will take a long time to collect a large amount of liquid. A storage tank comes to the rescue; its volume varies from 5 to 10 liters.

Water from a reverse osmosis system can be compared in quality to bottled water. However, its cost is much lower than store-bought analogues. Owners of these devices note significant savings, high water quality and ease of use.

Selection of the optimal option

Selecting the most suitable option is the first stage of choosing a filter for the sink. First, it is worth critically assessing the quality of the water flowing from the tap. It may differ not only in different areas of the city, but even in different houses (due to the different state of the plumbing system). The liquid may contain rust, sand, pathogens, infections and viruses. The presence of certain contaminants determines which water filter to choose for your apartment.

To ensure the accuracy of the results, it is necessary to conduct a laboratory examination. To do this, you need to take tap water into a clean plastic bottle and hand it over to specialists from the research laboratory.

After some time, experts will issue an opinion on the quality of the sample given to them and the content of various impurities and contaminants in it. A free version of the examination can be carried out at the sanitary and epidemiological station, although in this case you will have to wait a little longer for the results.

In the laboratory, water is assessed using more than 30 criteria. These include:

• presence of radiation contamination;
• high salt content;
• the presence of iron and lime;
• the presence of organic contaminants (germs, viruses, bacteria);
• presence of color, smell;
• assessing the level of transparency;
• pH level indicator;
• a lot others.

All these indicators will be reflected in an official document, in writing. Based on these data, you can select a suitable filter element.

Based on the results of the examination, it is much easier to decide how to choose a water filter for washing. If the water contains an increased amount of iron, chlorine or other chemical compounds, while the hardness is within normal limits, preference should be given to the following set of cartridges:

If the water hardness indicator significantly exceeds the norm, then flow-through devices should be abandoned. Even if the manufacturer indicated that this model softens water, it will not cope with very hard water. In addition, the cost of maintaining a flow filter with hard water will increase significantly, since it will have to be changed two to three times more often. The answer to the question: which water purifier is better for an apartment, in this case, will be a reverse osmosis system. It not only purifies water efficiently, but also performs a softening function.

Such a filter is especially necessary if there are small children and elderly people in the house; the quality of water for these categories is most significant.

Which manufacturer should you choose?

In stores you can find a wide variety of models produced by domestic manufacturers. All of them are distinguished by high quality workmanship, corresponding to world standards and analogues. It is Russian manufacturers that occupy leading positions in requests for “water filter for washing, rating 2019.”

Barrier

The owner of this brand is the Russian company METTEM Technologies, which was founded more than 20 years ago (in 1993). The company owns its own research laboratory and includes four production plants where filters for water purification are assembled in a fully automatic mode. The company produces both flow-through and reverse osmosis filters.

Most Barrier complexes consist of three stages; they are connected at the top by a lid; all elements are completely sealed and will not allow leaks. The filter can be equipped with any cartridges of your choice from the huge assortment produced by the company. They can be changed easily, in one motion, without the use of special tools or skills.

Aquaphor

The history of this brand is somewhat shorter than its previous competitors, but even in such a short period of time it managed to gain popularity among consumers. “New Water” was founded in Ukraine in 1996; in 2006, the manufacturer became a member of the World Water Quality Association WQA.

The Novaya Voda product range includes all types of filters, components and consumables for them.

Geyser

One of the oldest companies on the Russian market, the year of its foundation is 1986. The company’s intellectual property includes many scientific developments, which Geyser actively uses in its models.

In total, the manufacturer owns more than 20 patented developments. Particularly significant is the microporous ion-exchange polymer, which brings the company’s filters closer to the level of world leaders in this field.

Geyser can offer its customers any type of filter available on the market. It is convenient that the fastening and design of the replaceable Geyser and Aquaphor cartridges are completely identical, this circumstance makes them easy to replace.

From school we know that water is the source of life, but experience accumulated over the years suggests that ordinary tap water can become a source of serious health problems and cause breakdowns of household appliances. The thing is that we, consumers, often receive it of extremely unsatisfactory quality. There are many reasons for this: from inadequate water treatment to worn out, rusty pipes. We can only hope that in the future the situation will change dramatically, but for now you have to solve this problem yourself, and here all kinds of filters come to the rescue. Let's figure out how to choose a flow-through main water filter, a device that allows for the most thorough water purification and provides high throughput.

No. 1. Is a filter really necessary?

A water filter is necessary in most cases. If we are talking about apartment building, then the cause of water pollution may be outdated pipes. , which is often used in country houses and dachas, may be excessively mineralized or may not meet drinking water standards according to other criteria - it all depends on the location where the groundwater lies.

To the question Is a filter really necessary?, and if necessary, then which one, can only be answered laboratory analysis. Tap water may be too hard, which will cause damage to hair, skin and objects, in particular the washing machine and kettle. It may contain pesticides and pathogens, the harm of which is probably not even worth talking about. Water may contain some trace elements in increased quantities, which, if consumed regularly, can cause specific diseases. In addition, the water may smell bad, taste bad, and even have an unpleasant color.

In order for filtration to bring the desired results, you first need to recognize the enemy by sight, so experts recommend starting with testing the water at least according to basic indicators. It may turn out that, for example, there is no need for water softening at all, and then the costs of analysis in the future will more than pay off.

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

The problem of contaminated water is so large-scale that humanity has come up with a lot of different devices for cleaning it. We won't go into details, but among most popular filtration systems Today they use the following:

• jug filters and dispensers do not apply to flow filters - a certain amount of water is poured into them, which is cleaned over time by built-in cartridges. This solution is only suitable for purifying water for drinking and cooking, since the volume of the vessels, as a rule, does not exceed 3-4 liters;
  
• filter attachment for allows you to purify water from large mechanical impurities and improve its organoleptic qualities. The filter is suitable if the water quality is satisfactory and meets the standards, but you just want to improve it a little. Such a filter is easy to install, you can even take it with you when traveling, but it cannot cope with serious contamination, has low performance and requires frequent replacement of cartridges;
  
• filter "next to the sink" it is also easy to install, connects to using a special adapter and provides an average level of purification, eliminating large contaminants and unpleasant odors from the water;
  
• 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 replacing cartridges every 5-6 months, but the cost of its installation is higher than the previously listed options. This solution also has some disadvantages. The filter cannot cope with the most serious contaminants; it has limitations in terms of performance and cannot be installed on pipes with hot water.

If any of the listed filters allows you to purify water to an acceptable quality, you are very lucky. But if you’re unlucky, then don’t be upset, because there are flow-through main filters, which actually represent miniature water treatment station.

The main filter is built into the water supply system of an apartment or house, cuts 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. The filter can be installed for hot and cold water, and since it will be at the entrance, purified water will flow from all taps.

A flow-through main 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 very worn out. Such filters allow solve several problems at once:

• water purification from harmful impurities, chlorine and microorganisms;
• improving the taste of water and getting rid of metallic and other tastes;
• softening, because hard water negatively affects the skin and hair and leads to rapid wear of some household appliances;
• maintaining plumbing equipment in good condition. Conventional (non-mainstream) filters purify water only at one point of consumption, and through the rest of the pipes in the apartment it runs silted and contaminated with particles of rust and other debris, which gradually leads to breakdowns. With a 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 needs to be purified from water, you can use different cartridges;
• the ability to purify water for all water intake points with one filter;
• durability if used correctly.

Among the disadvantages Let us only note the difficulty of installation - you will need the help of specialists. You can service the main filter yourself, but if a blockage occurs, you can hardly do it without a professional. The cost of mainline systems is, of course, higher than that of simpler filters, but it is not exorbitant.

No. 3. Basic principles of operation of the main filter

Since the main filter is installed at the “entrance” of the water pipe into the apartment, it allows purify water for all water intake points. The main filter is multi-stage cleaning, and the purpose of all purification stages can be determined independently by assembling a system that is optimal under specific conditions.

The design of main filters may contain the following elements:

The throughput capacity of flow-through 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 also being made for pressure in the system. Main filters can be with low (0.1-0.2 bar) and high (0.4-0.5 bar) hydraulic loss. If you live on a high floor, where the pressure in the water supply is already low, then it is better to take a filter with minimal hydraulic loss. Additionally, a main pump may be needed.

For more productive work, it doesn’t hurt to equip the system pressure reducing valve, which allows you to reduce pressure fluctuations in the system and reduce water consumption. A check valve is also necessary - 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.

No. 4. Types of main filters

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

The main filter may include the following components:

• mesh main filter, or coarse filter, allows you to rid water of mechanical impurities, which is especially important in houses with old communications. The filter is made of a mesh made of stainless steel or other material with a cell size from 10 to 200 microns: the smaller the cell, the more debris the filter can retain. Often, mesh filters are installed in the main system in front of cartridge filters to reduce the load on them. The mesh, and sometimes there may be several of them, has a virtually unlimited service life - it only needs to be cleaned occasionally. If all the cells are so clogged that they cannot be cleaned, you will have to take a new mesh. There are filters with a backwash system, which are also called self-cleaning filters. Strainers may vary depending on whether they are used in cold or hot water systems. Any filters are suitable for cold water; for hot water - only steel or special plastic;
  
• disk main filters, or fine filters, clean from mechanical contaminants more thoroughly and use several technologies at once. These are blocks of compressed polymer discs with grooves that, when compressed, form a mesh that traps the smallest particles of dirt. These filters are easier to clean. Sorption cartridges and filters with ultraviolet radiation can also be used;
  
• cartridge main filters provide the highest quality cleaning. They allow you to filter particles as small as 5 microns, 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. You will have to change cartridges more often than clean the screens and discs, but the quality of cleaning here is much higher;
  
• reverse osmosis filters is rarely used and allows, by passing water under pressure through membranes at the outlet, to obtain pure distilled water. Such systems can be installed if the pressure in the water supply reaches 3-4 atmospheres.

Based on the number of cleaning stages, main filters are divided into:

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

We repeat, the choice depends on the quality of the water.

No. 5. Types of cartridges for main filter

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

No. 6. Manufacturers of mainline water filters

When it has been decided what and how we will purify the water, the next step is an equally difficult choice - it is necessary to decide on the equipment manufacturer. It is better to trust well-known 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 to purify water 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 purification;
• Aquaphor company produces main filters of small sizes, but at the same time the systems allow for high-quality cleaning from mechanical impurities, chlorine, iron and heavy metal salts. The equipment is made of stainless steel, which can withstand a wide range of temperatures, and plastic, which is designed for operation at temperatures of +5...+40 0 C;
  
• main filters "Artesian" They are distinguished by a convenient cleaning system, or rather self-cleaning. Mesh filters are complemented by a special string that vibrates under the influence of water flow, preventing contamination from remaining 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 an opportunity to observe the cleaning process. The company's product range includes filters for cold and hot water with a capacity of up to 60 l/min.

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

It is unlikely that any modern person doubts that water filters for apartments- not a whim, but a direct necessity. If only because the chlorine used in the central water supply system, although it kills most harmful microbes, is in itself harmful to the human body

In addition, water purified at Vodokanal, passing through old pipelines, again “acquires” iron salts. So the liquid from the tap is, at a minimum, tasteless, and at maximum, harmful. And additional water purification in the apartment should correct this situation

What types of filters are there for purifying water in an apartment? Let's go from simple to complex:

The simplest and most inexpensive devices are filter jugs with a small container where water is collected for filtration, and replaceable cartridges. They cope with rust, excess chlorine, and hardness salts. But they are unproductive and not very convenient if a lot of clean water is required. In addition, the water in the tap is always cold, but after standing in the jug, it becomes room temperature. Not everyone likes it in the summer

Flow-through water filter for apartments installed under the sink. A thin outlet is made from the common pipe, the water is filtered and flows into a special small tap intended for drinking water. The filter is quite expensive and bulky, but the cartridge only needs to be changed once every year or two, and the quality of cleaning is high

The most expensive and “serious” of apartment devices is main water filter for apartment. It can only be installed by specialists, as it is built directly into the water supply. But such a filter not only provides people with clean drinking water, but also protects expensive equipment (washing machines, dishwashers, coffee makers that draw water themselves, etc.) from hardness salts

The importance of water in human life is difficult to underestimate. It is needed daily in sufficient quantities. Not only the taste of dishes, but also, to a large extent, people’s health depends on its purity. To clean it, different filters are used. And to determine which water filters for washing are better, you should familiarize yourself with them.

To make the purchase of a water purification device as effective as possible, you need to choose one of two possible filter designs:

• flow-through;
• reverse osmosis.

Flow filters are considered the easiest to use, small-sized and affordable. They consist of several containers that are connected in series by the manufacturer. There may be several such containers. Typically from two to five.

Each of them has a filter cartridge. The cleaning system is attached to the water supply using a rigid or. The structure is installed under the sink, and water flows through the tap on the washbasin. This filter purifies only cold water.

Flow filter functions:

• purification of running water from large and small mechanical inclusions;
• sorption purification – elimination of harmful bacteria, taste and odors;
• ultraviolet cleaning, if provided by the manufacturer.

As a result, it turns out that such a device purifies running water to a state that is as safe as possible for use. It can be used both with a centralized water supply system and with an autonomous one (water from wells and wells).

Flow-type filters take up very little space under the sink. This system will fit perfectly in small kitchens, where there is very little space under the sink.

A flow-through filter under the sink consists of the following elements (there may be differences depending on the manufacturer):

• outlet for water connection;
• outlet for connecting a tap;
• filters – pre-cleaning, mechanical and sorption, fine and final;
• tap.

Reverse osmosis filters for water purification, which are installed under the sink, are larger and more expensive. This is due to the fact that the design provides two additional elements: a storage tank and a reverse osmosis membrane.

This membrane is designed to provide consumers with the most purified water possible. Thin polymer is rolled into a roll. The pores of this material are so small that only water molecules can pass through.

Naturally, the cleaning speed is much lower than that of flow filters, so it is advisable to use a tank to collect water.

There are pre-filters in front of the membrane, which remove all large impurities from the liquid. After the storage tank there is also a filter, the purpose of which is to eliminate odor and taste. The output is almost ideal water.

Due to the fact that the liquid is also purified from various beneficial salts and minerals, some manufacturers can equip the device with mechanisms for saturating the purified water with the necessary chemical elements. This makes the design somewhat more expensive, but the water becomes healthier.

It is advisable that the filter system tubes be neatly laid out and out of the way. Otherwise, they can be damaged and using cold water will be impossible.

How to choose the right filter?

Since choosing a modern water filter for washing is not easy, you have to listen to the proven recommendations of specialists and experienced users.

Before purchasing, you should pay attention to the following factors:

• the amount of clean water consumed by apartment/house residents;
• water quality;
• availability of the necessary space under the sink.

These factors are important because the choice of the right model will depend on them. On average, one person consumes up to 3 liters of water, in its pure form and as part of food and drinks. Accordingly, you need to calculate the filter performance to suit the needs of the family.

Since only reverse osmosis options can boast the best indicators of water purity, you should first consider them. If their productivity is not enough, then you need to stop at flow models. It is reasonable to equip them with softeners and iron removal cartridges.

Clean water at any time is what the installation of filters is for. Modern replacement of filter elements will allow you to get safe water in your home

You also need to pay attention to the condition of the water supplied from the tap. If it is excessively hard, then you need a filter with a water softening function.

If the water supply system includes lines made of old cast iron pipes, then the incoming water will contain inclusions of large mechanical particles. It is not enough to clean such water from contaminants; you also need to remove excess amounts of iron from its composition. Why should you choose filters with iron removal?

If the water supply system in the house is autonomous and it already has a filter at the entrance to the house, for example, a bottom filter or a pre-filter, then the simplest flow filters will do. You just have to focus on the productivity of the technology.

Subtleties of installation and operation

In order for the purchased filter to serve as long as possible, it must be installed correctly. Companies selling such devices often offer free delivery and installation by qualified specialists. This is an important argument in favor of purchasing equipment from such companies.

If you have plumbing skills and tools, you can do the installation yourself. An important stage in using a filter is preparing it for use. To ensure that there are no unnecessary odors or cloudiness when you first turn it on, you need to allow water to rinse the structural elements for the time specified in the instructions.

Also, do not forget about replacing cartridges and membranes - these are the main elements that help to obtain the most potable water.

Pure water without impurities, enriched with minerals, is the key to good health and longevity. To ensure that purified and maximally healthy water is always available in the house, it is recommended to install purification and filter systems. Our ranking of the best water purifiers 2019 will help you make your choice.

Water filtration began to be practiced at the dawn of the human era. One of the earliest purification methods, carbon filtration, has survived to this day. The Russian cleaning equipment market is rich in a choice of filters of different systems, cleaning levels, sizes and purposes. The main classification is by type of cleaning:

• mechanical filters are multi-level cleaning systems that are used to protect plumbing and household appliances from scale and dirt.
• ion exchange filters – systems for softening water hardness, operating on the basis of ion exchange resins. They filter not only iron, but also manganese, which most other systems cannot handle.
• Reverse osmosis filters are the most environmentally friendly and most efficient systems. They cope with the removal of all impurities and bacteria; before leaving, they additionally mineralize the water (optional).
• biological filters - the system works on the basis of microorganisms that purify water from organic contaminants. Used in aquariums and wastewater treatment plants.
• absorbent filters - the main cleaning component is absorbents that retain impurities (sorption process).
• aeration filters – water is purified using oxygen in special tanks.
• electric filters - purify water with ozone from all oxidized and dissolved organic and inorganic contaminants, however, they are very wasteful in energy consumption.
• filters of jug design - the design consists of a container for untreated water, a container for purified water and a carbon filter.
• cartridge filters - the design consists of several flasks, inside of which there is filter media for each type of impurity.

Choosing a water filter

The most important parameter for choosing a cleaning system is degree of water purification. Highlight:

• single-stage cleaning level (elementary) – this includes pitcher-type filters. Clean only coarse dirt;
• two- and three-stage purification level (medium) – filter large and fine contaminants;
• three-, four- and five-stage level of purification (high degree of purification) - filters from all types of contaminants.

Once you have decided on the degree of purification, you should choose filter installation type:

• filter with connection to the faucet - a special nozzle for the faucet that connects directly to the outlet of the mixer, productivity is only 0.3-0.5 l/min;
• filter with connection to the sink - a system “for the sink”, installed near the sink or on the sink, connected to the faucet mixer using a flexible hose, average productivity - 1-1.5 l/min;
• a filter with a permanent connection under the sink - an “under the sink” system, according to users, one of the best water purification systems, installed under the sink, directly connected to the water supply system, and has a second tap for purified water;
• desktop dispenser filter – the quality of water purification is not inferior to a “under-sink” filter, is not connected to the water supply system, is easy to maintain and fits harmoniously into the interior.
