We will send the material to you by e-mail
Increasingly, people are faced with the problem of poor quality tap water. And if in cities where there is a central water supply, it is still somehow purified (although not ideally), then in private areas this is not the case. In mountainous areas, with many springs, the situation is better, but in general, water from the water often requires high-quality filtration. Nowadays, many different installations for such cleaning have appeared on store shelves. And in this huge assortment of types, companies and models, it’s easy to get confused. Today we will try to figure out how to choose water filters for a private home and which device is needed in a given situation.
A water filter for the kitchen is a must these days.
It has long become not a luxury, but a necessity. In addition, now a person with any income can purchase such equipment. After all, manufacturers offer both quite expensive models and budget ones, such as filter jugs, which can be bought for 500-700 rubles. Of course, more expensive filters connected to the water supply system provide better cleaning, but there are nuances here too. After all, if you choose the wrong cartridges, the quality of the water will not change.
Important information! Before purchasing a treatment plant, you must call specialists to carry out a water examination. Only she can determine which elements are in excess in the water. It is based on the results of such an examination that a conclusion is made about the need to purchase filter elements with certain properties.
Household filters for water purification can be placed under the sink or on the wall, located directly on the pipe entering the living space, or even stand separately, without installation to the mains. It all depends on the quality of the required filtration and the financial capabilities of the person. It should be understood that purifying water for drinking is very important. The health of everyone living in the house depends on this. This means that the need for filtration should never be underestimated.
What determines the need for a water purification system in private homes?
The main problem of the private sector is that wells, like some wells, make it possible to extract groundwater. And human waste can easily get into them. For example, not far from a well or borehole there is a small garbage dump. It rains and everything that it washes out of the waste ends up in the soil. Water with harmful impurities reaches the first solid layer of earth through the soil and rushes to a well or well. Of course, the soil itself filters it a little, but such natural purification does not last forever. Over time, the soil itself becomes saturated with harmful substances on the way to the water well. As a result, even clean water that passes through it is saturated with pathogenic microorganisms.
Modern home water filtration systems handle these types of problems quite well. At the same time, simultaneously purifying the liquid from excess iron, chlorine and other impurities and even softening too hard. If we talk about filter jugs, which are a budget option, then they can be placed anywhere; they do not require a specific installation location. Of course, such a device will only be enough for one or two people. If there are more residents, then you should consider purchasing a flow-through or storage water filter for your home. This acquisition may well provide clean drinking water to several people.
Even if you are quite satisfied with the quality of water from a well or well, it is not always suitable for dishwashers or washing machines. After all, in any case, although rarely, some particles can get into it. For such cases, water purification in a private house can be carried out using main coarse filters. They cost little, but they only stop fairly large fractions.
We’ll talk about the types of water filters for a country house later, but for now we’ll figure out how things stand with this in apartments in Russian cities.
Are water purification systems necessary in apartments with centralized water supply?
There is only a clear answer to this question: they are absolutely necessary. With the rapid pace of construction of apartment buildings, as well as the lack of modernization of treatment facilities, the quality of tap water in our time leaves much to be desired. The water in the system requires purification from excess iron, chlorine, limestone, and sometimes even hydrogen sulfide and other quite harmful substances. We should not forget about the old age of communications. After all, rust from pipes also does not add cleanliness. It is for these purposes that coarse and fine filters are installed in apartments.
Water purification systems for an apartment can be just as varied, which means choosing the one necessary in a given case can be quite complicated. In this case, it is necessary to take into account many parameters. Water filters for an apartment, as well as for a private house, can be classified according to various criteria, namely:
- By installation method– storage, main or flow;
- By degree of purification– it can be rough or subtle;
- According to the basic structure– cartridge or disk.
Also, filters for water purification in apartments and private houses are distinguished by the cleaning method, of which there can be a lot. Today we will definitely analyze each of them in detail, but let’s talk about everything in order.
First, let's try to understand the classification of water filtration systems for apartments and private houses.
How water filters work and their classification
First you need to understand how water filters work. Depending on the number of degrees of purification, the water in them passes through elements (there can be from 1 to 5), which retain certain contaminants or saturate it with necessary substances. Most often, during five-stage purification, the water for the last of the elements is practically distilled. At the last stage, it is saturated with salts and minerals in the quantities necessary for humans.
If we are talking about jugs, then such a household filter for purifying tap water combines all stages in one cartridge. In this case, it is very important to choose a filter element with exactly the qualities that are required. Otherwise, water will not be purified when passing through the cartridge.
Important information! Filters for purifying water from wells must be equipped with coarse cleaning elements. If such water is poured directly into the same filter jug, then its cartridge will instantly become clogged with larger particles, which will not allow it to perform its functions.
Classification of water filters by installation method
Filters for water purification can be installed on the pipe entering the living space (main) or directly under the sink (flow-through or storage). At its core, a flow filter differs from a storage filter only in the presence of a special reservoir in the latter. Such devices allow you to use purified water for some time even if its supply to the system is stopped.
Now our main task will be to understand what work each of these devices does, what difficulties may arise when installing such equipment, and what you should pay attention to when purchasing.
The nuances of using main filter devices
A main water filter for a private home is considered preliminary. Of course, it purifies water from sand particles, and some models are capable of removing harmful microorganisms, softening water and improving its taste. But it should be understood that such installations will not be able to clean to the same extent as flow-type or storage-type devices.
Important! It is recommended to use main filters for water purification in an apartment together with flow-through filters. In this case, the water quality will be ideal. However, with little contamination, such installations can cope with filtration alone.

A rather significant advantage of main filters is the presence of a water pressure regulator. You should definitely pay attention to this when choosing and purchasing. The pressure regulator allows you to extend the life of not only faucets, but also household appliances such as a washing machine and dishwasher. The regulator eliminates the danger of water hammer that occurs when the pump is turned on, which is detrimental to household appliances.
The maximum number of degrees of purification for main filters is 3. If a device with one degree is selected, then here we can only talk about removing large particles, such as sand and rust. Such filters require replacing cartridges at least once every six months. In addition, they should be washed periodically, especially if the water is quite dirty and “rusty”.
Features of flow-through and storage water purification devices
The most common location of such filters is under the sink or near the water tap on the wall. It all depends on the availability of the tank and its volume. Until recently, units with five degrees of purification were considered the most effective, but now models with even six have appeared.
Flow filters for water purification in apartments are usually equipped with an additional tap, which is mounted on the sink next to the main one. At the same time, if main filters are installed for both hot and cold water, flow-through filters are often installed only for drinking water purification.
Important information! Not all flow-through water filters for private houses and apartments are capable of operating at normal pressure in the water supply system. Some models require additional pump installation. This is the only way it is sometimes possible to create a water pressure of 2.5-3 atm, necessary for the normal functioning of the cleaning device.
And here’s what netizens say about one of these devices from the Aquaphor brand:
olga655, Russia, Koryazhma: After its installation in 2013, we used water for cooking and drinking, it has been used for a long time, we changed the filter only in 2015 in April. The installation was easy to do on your own; it is advisable to treat the connecting hoses with sealant to avoid leakage. We ordered fast delivery from the company Aquaphor from the website. The customer support team works quickly and efficiently. The only drawback is that the faucet started leaking after six months. Convenient flow-through design. We didn't regret the money spent. We change the filter cartridges every six months, the water is no longer hard, tastes good, and we no longer have to descale the kettle every day.

Classification of devices by degree of cleaning
Here we can distinguish 2 possible degrees - coarse and fine. Surely the designations of the degrees themselves speak for themselves, but it is still worth considering devices with different cleaning conditions for a more complete understanding of all the nuances of the choice.
Important information! When installing a filter with multi-stage cleaning, you should not think that its first stages, considered coarse, can function for a long time without installing an additional main filtration device or at least settling tanks directly after the emergency valves.
Coarse water filtration devices
Such devices are a fine mesh that can trap particles. These devices can be either washable or non-washable. A special feature of coarse wash filters is that they have a special tap. By attaching a hose to the fitting and opening the valve, you can drain all the dirt contained in it. This makes cleaning the mesh easier. If you pay attention to non-flushing ones, they do not have such a function, which forces you to periodically disassemble the device and clean the mesh. It is these coarse water filters that include sedimentation tanks, which are found in almost every apartment or private house. They are installed directly behind the emergency tap or water flow meter. Such elements are also called filters for purifying industrial water, which contains many large particles.
Important information! Even if the water in your apartment or private house meets the standards, no one is safe from sand, lime or rust getting into it. And this can have a detrimental effect on household appliances connected to the system. It is for this reason that the installation of coarse filters is necessary.
Fine water purification: how it is achieved
The main task of devices that carry out fine cleaning is disinfection, iron removal and water softening. Some devices may have the functions of aeration, ionization and the addition of necessary salts and minerals.
In fact, fine water purification filters for apartments do a tremendous job. First, various elements gradually purify the water to a distilled state, and then give it the necessary properties and taste. Of course, such devices require periodic maintenance and replacement of filter elements, but this is a secondary issue. But at the same time, the quality of water (with the correct selection of cartridges) becomes close to ideal.
Most often, the installation of filters for fine water purification is carried out by specialists, although, with some knowledge in this area, you can install them yourself. You can find information on how to do this in one of our articles.
Important! When purchasing such devices, pay attention to the warranty terms. Some manufacturers will no longer provide warranty service if you install it yourself. Their requirements contain a clause stating that installation should be carried out only by qualified specialists.
Difference between filters based on their fundamental design
Based on their fundamental design, such filters can be divided into cartridge and disk. We can only say that the latter are used much less frequently, although they are in no way inferior in characteristics to the former. But this only applies to rough cleaning. It is for this reason that such elements are applicable only for trunk type devices. Let's try to understand what the fundamental differences between these filters are and what their operating principle is.
Cartridge filtration systems and how they work
With such systems everything is more or less clear. Water passes through reservoirs filled with various substances, which first purify it of impurities of one or another composition, and then bring it to the desired state.
Activated carbon is traditionally considered the main element of cartridge fillers. It may be cheaper (birch), or it may be more expensive (coconut shell coal). Various chemicals and minerals can also be added.
If we talk about rough cleaning, then often a winding of the finest metal wire or thicker cotton thread is used as a filter element in the cartridge. Such material is quite capable of trapping particles 20 microns in size. This is enough to filter out the smallest particles of dust, sand or rust.
Cartridge water filters have one drawback - the elements must be replaced after a certain period of time. And if more expensive and high-quality models are chosen, then such a replacement can cost a decent amount. But at the same time, the range of cartridge filters for water purification is quite large compared to disk filters, which we will now also dwell on in more detail.
Features and composition of disk filters
Less common, but not inferior, and in some cases even superior in characteristics to the previous elements. The filter itself is a package containing many polymer disks. On their surfaces there are trapezoid-shaped recesses. Thanks to these design features, under water pressure, some semblance of a mesh is formed, which traps small particles.
The peculiarity of this element is that if it becomes clogged, it is enough to rinse the bag under running water, squeezing and unclenching it a little. In this case, all dirt accumulated in the grooves is removed and the filter is ready for use again.
Here are some technical characteristics of disc water filters.
Table 1. Characteristics of disc filters for water
Thus, it becomes clear that all cleaning indicators are identical to the characteristics of cartridge elements. In addition, nowadays the manufacturer offers similar filters with automatic washing, which is quite convenient.
How filters are divided according to cleaning method
Quite a lot of species can be distinguished based on this parameter. This:
- Mechanical cleaning filters;
- Ion exchange devices;
- With reverse osmosis;
- Aeration units;
- Ozonation systems;
- Ultraviolet;
- Coal.
Everyone will have to decide for themselves which cleaning filters are best to purchase, but we will try to help with the choice. And to do this, it is necessary to more fully understand which of the household filters for purifying drinking water is intended for what and what functions it performs. Of course, the purpose of some elements can be understood just by the name, for example, such as hard water filters for a private home. But many varieties are not so simple, so let’s start.

Filters for mechanical water purification and their purpose
Mechanical cleaning is most often called primary, coarse filtration. All main filters can be classified as this type. Let's try to understand which manufacturers present products from this segment on their shelves. The most popular brands here are Atoll, Novaya Voda, Geyser and BWT.
Table 2. Popular mechanical water purification filters
Make and model | Photo | Filtration rate, l/min | Maximum pressure, atm | Cost, rub |
---|---|---|---|---|
Geyser 1P 3/4 32009 | 10 | 7 | 9000 | |
Atoll AFR-1/2CB (set of 2 filters) | 25 | 16 | 10000 | |
BWT Protector Mini 1/2 Н604Р11 | 27 | 16 | 5000 | |
PRIO New Water A082 | 15 | 26 | 6000 |
As you can see, the price range is quite wide. And this does not necessarily mean lower quality cheaper products. The point here is more about the brand and its recognition. After all, any company initially works for its name, and then, regardless of the quality of its products, the name works for it.
In general, mechanical filters for water purification are selling out very quickly these days. From conversations with the seller of one of the retail outlets specializing in such a product, we were able to find out that most often, before the weekly delivery, a queue of people wishing to purchase main filters has already formed. At the same time, there is not enough such products for the entire week.
Ion exchange filters: how they differ from others
- Ultra-high level of cleaning;
- Removes all bacteria, heavy metals and viruses;
- Removes dissolved gases of residual chlorine, petroleum products, pesticides, phenol, compounds of hazardous metals and other toxic substances;
- Household filters for softening water retain the mineral composition in it after purification;
- Stabilizes the pH level to optimal for humans;
- Helps water charge with negative ions;
- Converts organic salts for easy absorption by the body;
- Provides high filtration speed, up to several liters per minute;
- Durable cartridges and easy to replace;
- Has a variety of installation options;
- Allows visual control of the degree of contamination;
- Provides the ability to install additional degrees of purification.
In essence, ion exchange is water purification by replacing heavy metals with neutral ones. Of course, we won’t go into a full course of chemistry, but consumers consider this method to be quite effective. On average, the cost of such filters on the Russian market has stopped at 1500-3000 rubles. However, you can also find premium models at a price of 90,000-100,000 rubles. The main manufacturers are still the same - “Aquaphor”, “Geyser”, “New Water” and “Barrier”.
Reverse osmosis filters for home are the most common type
Such reverse osmosis devices for water purification are installed under or above the sink. The quality of cleaning systems with reverse osmosis reaches 99%. The cost of such devices is distributed as follows.
Table 3. Atoll filters
Make and model | Photo | Productivity, l/min | Number of purification levels | Price, rub |
---|---|---|---|---|
Atoll Patriot A-550 | 0,09 | 5 | 8000 | |
Atoll A-310E/D-30 STD | 2 | 3 | 5200 | |
Atoll A-211E/D-21 STD | 3,8 | 2 | 5000 | |
Atoll Premium A-560Ep/A-550 MAXp | 0,18 | 5 | 22000 |
Table 4. "Aquaphor"
Aeration system - what is it?
The name itself speaks for itself. Aeration means saturating water with oxygen. Many may ask - how is oxygen saturation related to filtration? The answer is simple. Aeration by itself does not purify water, but with the help of other substances, saturating it with oxygen, it helps improve the quality of the final result. For example, aeration of water from a well improves not only its taste, but also increases the level of oxygen in the blood, which has a positive effect on human health. Surely many people know what an “oxygen cocktail” is. This is precisely the principle applied here.
The use of a water aeration system is indicated for people with heart disease, hypertension and hypotension, as well as diseases of the gastrointestinal tract. But, in any case, first you should consult with a specialist.
Ozonation: on what principle does such a system work?
Surely every schoolchild knows that ozone promotes oxidation. That is why water is in some cases purified by ozonation. This means that it is aimed more at deferrization. If there is no excess iron in your water, then such purification is clearly useless. Ozone increases the intensity of iron oxidation, as a result of which the particles begin to be covered with additional processes. In simple terms, they “rust.” Having increased, such particles can no longer pass where simple water seeps freely.
Important information! Ozonation of water is contraindicated for allergy sufferers. Ozone, in addition to its main job, partially remains in the water. As a result, an allergic person, by consuming such water, automatically increases the risk of a reaction.
Whether ozonation is beneficial or harmful - this question should be left to the doctor. But reviews of such devices speak volumes.
Denissasha, Ukraine, Chernivtsi: Ozone, in acceptable concentrations, has a lot of useful properties. You can ozonate drinking water, air, treat food, places of cuts, burns and trophic ulcers. Ozonation of water and products is safe, all microflora and microfauna in the water die, even those that survive chlorination, and the remnants of drugs, hormones and other gifts of big chemistry are washed out of the meat during processing. It has been tested that processing homemade village chicken practically does not produce results; chicken meat bought in stores after processing is almost always covered with nasty mucus that needs to be washed off. How, what and how much to process is written in the instructions for the ozonizer. More details on Otzovik: http://otzovik.com/review_167392.html
Ultraviolet radiation and its effect on the body
Here we can say with confidence that such devices fight pathogenic bacteria and microorganisms quite effectively. As an example, we can cite UV lamps, which can be seen in treatment and operating rooms of clinics and hospitals. Like them, ultraviolet water filters completely disinfect liquids. But there are also negative sides. All useful substances contained in the water also die.
Carbon filter and its properties
Coal itself is an absorbent substance. This means that any resins, formaldehydes and other similar substances are retained by them. Today, a carbon water filter is considered the best in terms of purification.
In fact, if you think about it, not a single cartridge can do without such a layer. This suggests that the use of a carbon filter for water purification ensures purification from the most common harmful substances.
Average cost of water filters for private homes
Prices for water filters for private houses and apartments may vary. If you compare the most famous manufacturers, you can understand the average dependence. Reverse osmosis filters are taken as an example.
Brand | Average cost in Russia, rub. |
---|---|
Atoll | 19000 |
Geyser | 16000 |
Aquaphor | 11000 |
New Water | 10000 |
Of course, all prices are given in average terms, but this table can show an approximate concept.
It turns out that buying a water filter for a country house, cottage or apartment is not so difficult. After all, the cost of such equipment is low. And in general, is it worth saving on health?
Article
The quality of tap water has long ceased to be considered sufficient for consumption without additional purification. The specific taste and smell of untreated water can spoil the prepared dish, and drinking it is completely unpleasant. For this reason, many people install a water filter under the sink in the kitchen of their house or apartment; which one is better and what characteristics are important when choosing – we’ll look at it in this article.
Why is it needed? The operating principle of various models. Which flow-through water filter is best? Table with characteristics of the most popular models.
Which water filter to buy for washing: the best domestic manufacturers
There is a lot of debate about whether it is worth giving preference to domestic manufacturers, or is it better to purchase a foreign model from a famous brand? It is difficult to answer this question unequivocally, but it is important to understand that most of our companies operate in accordance with international standards and are in no way inferior in the quality of their products to other manufacturers.
Water filter Barrier
Barrier is one of the most popular brands you can find on the market today. Together with Aquaphor, it occupies a leading position. It appeared in 1993 and belongs to the domestic company “METTEM Technologies”. Being a fairly large-scale enterprise, Barrier owns four factories, fully equipped with high-quality German equipment. In addition, they have their own research center.
Both reverse osmosis and standard flow filters come off their conveyors, most of which have three degrees of purification. A special feature of their models is the presence of a special one-piece lid, which ensures no leaks. The filter capacity is up to 2 liters of water per minute. Replacing cartridges in water filters for Barrier sinks is done simply, within a few seconds.
Household filters for drinking water purification Aquaphor
The main competitor of Barrier filters and an equally popular manufacturer of water filters is Aquaphor. The company first announced itself on the market in 1992 and today has two large factories, one of which is located in St. Petersburg.
Among the brand's products you can find both main and reverse osmosis systems. But filter jugs for water purification are especially popular. You can buy them for several hundred rubles, and yet the level of cleaning they offer is more than high.
In addition, the company’s specialists presented their own development: the Aqualen sorbent. Its thin carbon fibers are capable of providing a particularly high level of purification of water passing through it.
Filters for water purification New water
Buying New Water filters is also very simple. Despite the fact that the company is slightly younger than the previous two and was founded in 1996, already in 2006 it received membership in the world Water Quality Association, which specializes in water quality. The company's product range includes both reverse osmosis and flow-through cleaning devices, as well as a variety of types of replaceable cartridges.
Water filters for sink Geyser
Geyser is one of the oldest, and therefore respected, companies on the water purification filter market. Having existed since 1986, it has managed to offer its customers a huge variety of scientific developments, which are now used in filters of its own production. During this period, the company was officially issued more than 20 patents.
Among the developments of this company, which have been recognized throughout the world, one can highlight a microporous ion-exchange polymer. It was he who provided the company with global popularity and allowed it to take a position in the world market. However, users are often much more interested in the fact that the cartridges are easily replaced with Aquaphor cartridges, which greatly simplifies the procedure for replacing them.
Reverse osmosis water filters Atoll
Buying an Atoll water filter means getting American quality at a very reasonable price. The thing is that the components are produced in the United States, while the assembly is carried out in Russia. All products are certified according to the international NSF standard, and therefore are recognized as one of the best.
Depending on the purpose, four different filter models are available to solve a particular problem. All devices have three stages of cleaning.
Rating of water filters for flow-through sinks: 5 best models
In order for you to choose the most suitable model, we will consider the five most popular options that were recognized by users as the best. The table will allow you to compare the characteristics, and a detailed description of the advantages and disadvantages will allow you to form your own opinion about each model:

EXPERT Ferrum (Barrier): the best filter for purifying water with high iron content
The advantages of this model include the following indicators:
- the filter provides high-quality water purification from impurities such as iron, chlorine, etc.;
- the cost of the device is more than moderate;
- installation of the filter is extremely simple;
- the filter does not affect the overall water pressure in the pipes;
- It’s very simple to buy a cartridge for the EXPERT Ferrum water filter, as well as replace it yourself;
- The filter is small in size and has a nice design.
But according to reviews, the Barrier EXPERT Ferrum water filter has the following disadvantages:
- copes quite poorly with increased hardness and practically does not soften water;
- replacement cartridges have a high cost, which, with constant use of the filter, significantly affects the budget;
- Long-term use of the filter leads to the appearance of a specific taste characteristic of coal.
Helpful advice! If any foreign taste or odor appears in the water, first drain at least 5 liters of water. If the situation does not improve, then the problem is in the filter itself and it needs to be replaced.
From the above information, we can conclude that this model is an excellent choice if your goal is to purify water from iron impurities, which often cause rust stains in the sink and bathtub. Moreover, drinking such water is not only unhealthy, but also tasteless, since the taste of iron is pronounced. Here's what the reviews say:
“An analysis of our water showed that the iron level is very high, but the hardness is fine. Therefore, this filter was ideal for us. Moreover, it is very inexpensive, and the cartridges are very easy to change.”
Evgeny Astakhov, Ekaterinburg
The filter is simply not designed to reduce water hardness; however, at its low price, the EXPERT Ferrum Barrier water filter fully performs its main function of iron removal. The system is located under the sink, and replaceable cartridges are changed in one motion.
EXPERT Hard (Barrier): membrane filter for water purification
The positive aspects of using this filter can be formulated in several simple points:
- Thanks to this purification, the water becomes much tastier, cleaner and more transparent, the smell characteristic of chlorine impurities completely disappears, and scale does not appear in the kettle even after a long time;
- the filter design is designed in such a way that thin flasks easily fit even into very limited space under the sink and at the same time look very aesthetically pleasing;
- the filter does an excellent job of softening water;
- the service life of the cartridges for these filters is at least six months, and replacement is done in one motion;
- the filter is capable of processing more than one liter of liquid per minute;
- Such a device is not too expensive and is very easy to install.
But EXPERT Hard also has disadvantages, which are best known in advance:
- the device is quite heavy and therefore it is best to place it on the floor or the bottom of a kitchen cabinet;
- The basic configuration of the filter includes a special ball valve, which, as users note, is not very convenient to use. This is primarily due to the fact that there is no nut for it that would allow it to be unscrewed if necessary;
- Another difficulty that often arises during the installation process is the mismatch of the adapter in relation to some mixers;
- immediately after installing the filter, the water from the tap will flow cloudy, so the first at least 10 liters must be simply drained into the sewer;
- the cartridge responsible for softening is not very effective over a long period of time if the tap water is very hard.
To summarize, we can say that this flow filter can inexpensively solve the main problems associated with purifying water from free chlorine and softening. It is not intended for very harsh operating conditions, but as a simple household option it copes with its tasks perfectly.
Water filters for sinks Aquaphor Crystal N
This filter from the Aquaphor company is especially popular among users, and there are a number of reasons for this:
- it has a very convenient design, and all the materials used for its manufacture are highly durable;
- the manufacturer indicates that cartridges need to be changed every year and a half, which is a considerable service life for elements of this type;
- copes well with the function of softening tap water;
- has a positive effect on water characteristics such as smell and taste.
Disadvantages of using the Aquaphor Crystal N filter:
- The cartridge responsible for softening the water does not have a very long resource. On average, it is enough to process 200-250 liters of water, although this largely depends on the degree of its initial hardness;
- The softening module can be restored by washing it regularly. However, performing this procedure every 2 months is quite tedious, and replacing the cartridge with a new one is expensive.
Helpful advice! If you're daunted by the prospect of constantly worrying about the need to maintain replaceable modules, you might want to look into cartridge-less water filters.
Perhaps the only drawback of this filter is the need to regenerate the softening module. Otherwise, the device copes with all functions perfectly, providing clean and tasty water, purified of all unnecessary things. The device itself looks beautiful and is inexpensive.
Expert M410 (New Water): a good choice of water filter for washing
This device has a number of unique advantages that make it indispensable in certain operating conditions:
- The filter width does not exceed 10 cm, which allows it to be used even in very limited space under the sink. But even if there is enough free space, this option allows you to save space in order to use it to place other necessary items;
- High-quality plastic is used for manufacturing, and the manufacturer pays special attention to the reliability of connections;
- The faucet for the drinking water filter that comes with the kit looks very nice. It will be a worthy decoration for any kitchen;
- for a very reasonable price you get a complete set of parts necessary for installing and operating the filter;
- the filter does an excellent job of eliminating free chlorine, which makes the water much tastier and clearer;
- As many as five degrees of purification are used, one of which is ultrafiltration;
- The water filtration speed is quite sufficient for everyday use, and replacing cartridges is very quick and easy.
This model does not have any serious drawbacks, however, users noted that the replacement cartridges for this model cannot boast of a low price, and the water softening element often requires maintenance after just a month of regular use.
This compact and beautiful model includes as many as five degrees of purification, including ultrafiltration. This undoubtedly makes the filter one of the best candidates to purchase. Of course, too hard water can become an obstacle to the comfortable use of the device, but otherwise it copes well with its tasks.
Crystal Quadro (Aquaphor): the best filter for water sinks with the ability to select modules
There are several advantages of this filter:
- you can select modules for your filter individually, which allows you to independently determine the most suitable configurations that can solve current problems associated with the presence of foreign impurities in water;
- cartridges can be replaced directly with the flask body, which greatly simplifies the replacement procedure;
- The device is compact in size.
The disadvantages of this device include a number of the following characteristics:
- the presence of a fourth cleaning stage significantly increases the price of the device, while it is not always necessary and justified;
- due to the design features, it is necessary to replace not only the cartridge, but also the flask, which also increases the cost of replacement elements;
- Like most flow filters, scale appears on this model after just two months of use.
Generally speaking, this is a compact filter that will allow you to select the modules yourself, thus ensuring the most effective cleaning. However, this model can hardly be called economical, which is worth considering before purchasing it.
Reverse osmosis systems: which filter is better for water purification

- The kit does not include spare retaining rings;
- Such a filter is not cheap and it can only really be repaid if the daily consumption is more than 20 liters per day;
- Users also note that the key, made of plastic, which is designed to unscrew the flasks, breaks very easily.
If you are not concerned about the cost of the device or you are simply ready to spend serious money on high-quality water purification, this model can be called an ideal option. All components are imported and boast high quality. The filter itself is characterized by high performance, and therefore is suitable for an apartment or house where a large family lives.
Barrier PROFI Osmo 100, household filter for drinking water purification: reviews and characteristics
First of all, this simple model is famous for its low cost and the presence of as many as 5 stages of cleaning. But besides this, the following points stand out:
- all flasks can be disassembled, which allows for significant savings in the future;
- after cleaning, foreign odors and taste disappear;
- cartridges have a long resource and do not require frequent replacement;
- The quality of the parts leaves much to be desired. This applies both to the plastic itself and to such little things as the lack of a special latch, which should ensure a reliable connection of the elements;
- the four-way valve emits a specific hum when the storage tank is empty;
- it is necessary to constantly monitor the pressure level so that the filtration system works properly;
- water consumption during the filtration process is very high;
- This model can hardly be called compact. Most likely it will take up all the free space under the sink.
- the membranes used are made in Japan and meet all quality requirements;
- both the filter and the faucet included in the kit boast an original design and ease of use;
- the filter is easy to install yourself, but at the same time you can always get qualified help by using the support service on the company’s official website;
- the membrane, like the cartridges themselves, are easy to maintain and replace.
- the rather high cost of both the model itself and individual components, in particular cartridges;
- filtered particles tend to clog the membrane, which negatively affects the water supply pressure;
- Unfortunately, leak tests are not provided for these water filters for washing, which leads to the risk of encountering a leak immediately after installation.
Reverse osmosis filter Barrier Profi Osmo Boot
Among the shortcomings most discussed by users on forums and thematic portals are:
In short, this is practically the cheapest version of a five-stage water purification filter that you can find. In this regard, one has to face a number of difficulties, such as increased water consumption and the need to control pressure. However, this model is quite inexpensive. Here's what those who purchased this filter say on the forums:
“The main thing that attracted me to this under-sink water filter was the price. Initially, I didn’t plan to spend much on this, and therefore such a cheap option suited me quite well. In general, it’s a very economical thing: I installed it myself and everything is fine. Fortunately, I don’t have a water meter.”
Nikolay Tyumentsev, Ufa
“Everything is fine with the filter, except that it is very sensitive to pressure. I had to spend time and solve this problem once, but now everything works great and there are no problems.”
Konstantin Pritulny, Volgograd
Expert Osmos MO510 (New Water): compact and convenient water filter
Buying a membrane filter for water purification of this quality means paying due attention not only to the quality of the water itself, but also to the design of the device. Here are some of its benefits:
Disadvantages of using this filter:
This model is quite suitable for water purification, provided that the content of mechanical impurities is not too high. However, it is better to entrust the installation of this particular filter to a professional.
Devices without replaceable cartridges: main-line water purification filters
Water filters without replaceable cartridges occupy a special place in the modern market of water purification devices. One of the most prominent representatives of this category is the titanium water filter Titanof. Reviews about it unanimously indicate both ease of use and high quality cleaning. The efficiency of using a titanium filter is several times higher than the installation of a coarse water filter, as well as most membrane models. Here's what users say about this device:
“We have been using the Brita water pitcher filter for quite some time. Buying a cartridge seems to be not too expensive, and not too difficult, but in reality, you very soon get tired of thinking and remembering about it. Therefore, when choosing a filter for the sink, we chose a titanium one primarily because it does not have replaceable cartridges. And the quality of water purification is at the highest level.”
Miroslav Velikhodov, Ryazan
The titanium filter provides high-quality water purification from free chlorine, iron, aluminum, metal salts, as well as nitrates and other unsafe chemical compounds. At the same time, the filter does not affect the mineral composition of water.
Helpful advice! If you are just deciding where to buy a water purification filter, then it is best to place an order on the manufacturer’s official website. This way, you can at least be sure that you purchased an original product, and if there is a problem, you can contact the manufacturer directly.
Installing a water filter under the sink yourself
Having finally decided on a suitable model and purchased it, all you have to do is install the filter in place and start using it. The easiest way is to invite a master to do this, whose qualifications will allow him to do this with the highest quality possible. However, often the considerable price of household filters for drinking water purification pushes people to save on installation.
Installing a filter for water purification can be done independently. But in this case, it is necessary to take into account both the basic rules for installing such devices and the manufacturer’s individual recommendations.
Let's consider the general procedure for installing a filter for water purification under the sink:
- First of all, remove from under the sink anything that could get in the way or get wet during operation. Prepare a cloth, bowl or bucket.
- Turn off the water and relieve pressure in the system by opening any of the taps.
- Unscrew the water supply hose in the place where the transition from the common line to the mixer is located.
- Be sure to measure the current pressure on the line and, if the indicator does not match, take the necessary measures: if the pressure is too high, a reducer is installed, and if the pressure is too low, a special pump is installed.
- According to the instructions provided by the filter manufacturer, secure all components. At the same time, do not forget about small but important details, such as gaskets and rubber bands, since they are the ones who ensure the tightness of the system.
- Take care of the high-quality connection of the drinking water faucet with the filter. Inspect all joints in advance and make sure they are strong.
- Before checking, place a bowl under the sink and place a rag around it in case there is a leak somewhere. Allow the water to drain down the drain for at least 10 minutes. If everything is in order during this time, you can return everything previously removed to the sink.
Helpful advice! In order to increase the service life of the rubber parts of the filter and prevent them from drying out, pre-lubricate them with Vaseline or silicone.
When you decide to take care of the quality of the water you use for drinking and cooking, you will definitely be faced with a difficult choice. But after carefully reading the reviews of under-sink water filters, operating features, as well as the main characteristics, you will certainly understand which filter you need to buy for under-sink water purification.
Sink filters use replaceable modules through which water is filtered sequentially. The cleaning method is determined by the “filling” of the modules and the technical design of the model:
- . Water is forced through the membrane cartridge using pressure from the water supply network. Water with impurities cannot pass through the membrane and is drained through the outlet drain tube.
- Use activated coconut charcoal. It, like a sponge, absorbs harmful impurities from the water flow: chlorine and organochlorines. At the same time, like a sieve, it retains rust, silt, sand and other particles. This filter is suitable for removing major contaminants from drinking water.
- The Aquaphor company offers another type of filter for washing: . DWM are models based on reverse osmosis technology for convenient home use. They take up 2 times less space than classic reverse osmosis systems and can operate at low pressure: 2 atm is enough (“classic” requires 3.5 atm).
If you are selecting a filter based on pollutant type, please note:
- Any good sink filter can handle the main water pollutants. For specific impurities, the installation of special systems may be necessary.
- Not all contaminants can be identified by the sight, taste, or smell of water. To be sure that you are solving exactly the problem, it is better to first have your water tested.
Tap water often leaves much to be desired; it is harmful to health and negatively affects the taste of drinks and dishes.
There are 3 ways out of the situation:
- Come to terms with it.
- Buy bottled water.
- Install a filter.
The most common type of filter is under the sink. This is a water purification system that is installed under the kitchen sink on the floor or wall. Using flexible connections, the filter is connected to the water supply, and a separate tap for filtered water is installed on the countertop or sink surface.
What types of water filters are there for sinks?
Flow filters
The design consists of 2-4 modules connected in series. Water goes through several stages of purification, each filter has its own purpose:
- Mechanical cleaning filter. Removes solid particles from water. It is a cellular fabric or mesh material. Cell size - up to 30 microns.
- Fine filter. A carbon filter that traps particles up to 5 microns in size effectively fights odors.
- Ion exchange filter. Its main purpose is water softening. Calcium and magnesium ions are replaced by sodium, chlorine ions and other soluble compounds. The cartridges contain both artificially synthesized resins and sulfonated carbons.
- Iron removal elements. The filter contains chemicals that help bind the iron and oxygen atoms. Metal oxides form a deposit, which remains inside the filter.
- Antibacterial filter. Purifies water from bacteria and viruses; manufacturers claim that silver ions are used in the manufacture of such filters. Ultraviolet lamps are used less frequently.
- Combined. They are almost never used in multi-stage systems, only in single-flask filters. One cartridge combines several types of filter elements.
Important! The composition of tap water must be taken into account! The tougher it is and the more impurities it contains, the more often the cartridges will have to be changed.
Reverse osmosis systems
The design of a reverse osmosis system is similar to a flow-through one, the difference is in additional modules and improved filters. Most often, membrane filters with micropores are used in such installations. Almost all organic and inorganic substances remain on the filter; contaminants are removed by a stream of water into the sewer. According to performance, filters are:
- 50G - this marking indicates a water purification rate of up to 200 liters per day.
- 100 G - productivity about 400 liters per day.
Important! Reverse osmosis filters purify water longer than flow filters, so they are often equipped with tanks for storing filtered liquid (up to 10 liters).
Reverse osmosis systems must have a polypropylene filter (coarse cleaning), a carbon or iron-removing element, and less often an ultraviolet lamp. Only after this does the water pass to the membrane filter. It is very important that the water supply system has normal pressure (1.5-3 bar). If the pressure is low, you will have to purchase an additional injection pump.
Since the water that has passed through the reverse osmosis system is close in composition to distilled water, it will not benefit the body. The necessary salts and compounds have simply been removed from it. The mineralizer filter restores its structure and saturates it with minerals. The liquid is enriched with magnesium, calcium, sodium, silver ions, sulfites, chlorides, fluorides. A high-quality filter allows you to obtain water with a composition close to mineral water.
How to choose a water filter for washing
The first thing you need to do is submit the water for analysis (to a sanitary and epidemiological station or testing center). In the laboratory, the sample is checked for the presence of heavy metals, salts, organic impurities, and pathogens. The characteristics of color, PH, transparency, smell and others are determined. You will be given a detailed document on the basis of which you can select a cleaning system.
What problems does a water filter solve?
Most often, users encounter the following problems:
- Increased content of chemical compounds (chlorine, heavy metals and others). The cleaning system must have a polypropylene cartridge (mechanical), carbon and iron removal.
- High water hardness. It is better to give preference to a reverse osmosis system. On flow filters you will have to change cartridges almost every month - this is extremely unprofitable. In osmotic systems, a membrane filter copes well with this task.
- Increased organic content. Water may contain microbes, viruses, bacteria, which a disinfecting filter will help deal with. This is a silver ion cartridge or an ultraviolet lamp. A reverse osmosis membrane filter will also come in handy.
What to look for when purchasing
When purchasing a filtration system, you should also pay attention to other criteria:
- The number of purification levels (from 2 to 6) - the more, the better quality water you will get. If the water differs slightly from the norm, a 3-stage filter is sufficient.
- Performance. With flow filters everything is clear, but a reverse osmosis system purifies water more slowly. The manufacturer must indicate the number of liters per hour in the passport.
- Quality. The materials from which the equipment is made must comply with environmental and sanitary standards. Don’t be lazy to ask the seller for certificates.
- Availability of components. It is easier to find replacement filters and spare parts on models from well-known manufacturers.
- Dimensions, presence of a water storage tank.
