The rating of wash water filters included the most efficient, reliable and proven systems. They are slightly different in parameters, so for each situation there is its own good model. The main thing is that the unit adequately performs its cleaning tasks, which will preserve your health.

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

In order for the purchase of a water purification device to be as effective as possible, it is necessary to dwell on one of two possible filter designs:

• flowing;
• back osmotic.

Flow filters are considered the most easy to use, small-sized and affordable. They consist of several containers, which are connected in series by the manufacturer. There may be several such containers. Usually two to five.

Each of them has a filter cartridge. The cleaning system is attached to the water supply system with a rigid or. The structure is installed under the sink, and water flows through the faucet on the washbasin. This filter cleans 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).

Filters flow type take up very little space under the sink. This system is perfect for small kitchens, where there is very little space under the sink

The flow 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 crane;
• filters - preliminary cleaning, mechanical and sorption, fine and finishing;
• tap.

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

Such a membrane is designed to give consumers the most purified water. The thin polymer is rolled up. 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 water collection tank.

Before the membrane there are pre-filters that 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 perfect water.

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

It is desirable that the tubes of the filtering system are neatly laid and do not interfere. Otherwise, they may be damaged and use cold water will be impossible

How to choose the right filter?

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

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

• the amount of clean water consumed by the residents of the apartment / house;
• water quality;
• the right place under the sink.

These factors are important, since the choice of the desired 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, it is necessary to calculate the filter performance for the needs of the family.

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

Clean water at any time, this is what the installation of filters is necessary 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 that is supplied from the water supply. If it is too hard, then you need a filter with a water softening function.

If the water supply system includes lines from old cast-iron pipes, then the incoming water will be with inclusions of large mechanical particles. It is not enough to clean such water from pollution, it is also necessary to remove an excess amount of iron from its composition. Why should you opt for 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 or pre-filter, then the simplest flow filters will do. You just have to focus on the productivity of technology.

Subtleties of installation and operation

In order for the purchased filter to serve as long as possible, it is necessary to install it correctly. Companies selling such devices often offer free delivery and installation by dedicated professionals. This is an important argument in favor of buying equipment from such companies.

If you have plumbing skills and tools, then you can do the installation yourself. An important step in using the filter is its preparation for work. So that when you first turn on there are no extra odors and turbidity, you need to let the water 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 get the most potable water.

Conclusions and useful video on the topic

This video will help you to correctly determine the main differences and advantages of flow and reverse osmosis filters:

In the next video we will talk about reverse osmosis systems. Here are the specific results of measurements of the main indicators of water:

In conclusion of the article, it should be noted that both categories of filters make it possible to obtain water of the required purity. For any water supply system, it will be possible to find the right equipment, regardless of the budget.

The accuracy of the selection will be significantly affected by a preliminary analysis of tap water. This will allow you to understand how hard the water is, which trace elements are in excess, and which minerals are in short supply.

Why purify water at all?

Municipal water supply (vodokanal) purifies water in the following way. Water is taken from a reservoir or well, and then a coagulant is added to it - a substance that collects small particles of impurities into large flakes. Then mechanical filtration is carried out, which removes these flakes from the water. Next comes the bactericidal treatment - chlorination.

The resulting water meets sanitary standards. This means that it is not toxic and not hazardous to health in the short term. That is, MPC (maximum permissible concentration) of harmful substances in such water is NOT exceeded. Yes, substances CAN be there, but in quantities allowed by the standard. To make it completely clear: you can drink such water without the risk of dying immediately after drinking. But such water may contain chlorine residues, pesticides and other organic matter. After passing through the pipes, the water collects colloidal iron, rust and heavy metal ions. All this can be part of both ferrous and non-ferrous alloys, from which pipes, taps, fittings and other plumbing fixtures are made. It won’t hurt you right away, but in the long run, drinking such water will definitely affect your health. Therefore, water purification is an important and necessary matter. Especially if there are children in the house (my wife and I are planning to get one soon).

Practice

To find out how filters from different manufacturers differ from each other, and which filter cleans how, my colleague and I conducted a small “investigative” experiment. You can repeat it even at home with the filter that you have at home. True, you will have to spend some money on the purchase of reagents - there are sites that sell equipment and materials for chemistry lessons, you will find everything there. In this regard, I was lucky with the work - I managed to agree with the laboratory and get the reagents there.

Which pitcher is best?

I used jug filters all those years that I wandered around rented apartments. To be honest, I have never particularly seen the difference between the filter-jugs of different brands and did not even think that it exists in principle: they all cost the same plus or minus and plus or minus look the same. I always chose based on the price tag, volume and color of the lid. Therefore, on the test high hopes didn't get different results.

For the experiment, we chose the three most popular filters, judging by the reviews on the Internet: Aquaphor Provence with the A5 module (cartridge price - 240 rubles), Barrier with the Standard 4 module (cartridge price 210 rubles) and Brita Marella "with the module "Maxtr Universal" (the price of the cartridge is 350 rubles).

Everything is fair: completely new filters were tested. For each, just in case, a spare cartridge was purchased.

Before the tests, the cartridge of each jug was washed with about a liter of water - according to the instructions, this is the only way they give out full cleaning power, otherwise the experiment will not be indicative.

First of all, it was decided to check how the jugs cope with pesticides, toxins and other organic matter. The issue is important, because, as mentioned above, the water utility does not remove most of the organic pollutants from the water.

The presence of pesticides, toxins, organics and organochlorines in water cannot be determined with the naked eye and taste. Therefore, in our experiment, their role was played by the dye "Methylene blue", which even at a low concentration (10-50 µg/l) colors water into a radical Blue colour. In GOST 4453-74, this dye is used to determine the sorption capacity of activated carbon, that is, the ability of coal to bind organic substances contained in water. It is important for us that methylene blue, firstly, is similar in chemical structure to pesticides and toxins, and secondly, even in small concentrations it is perfectly visible without any instruments.

The dye is sold in pet stores - it is used to disinfect aquariums, and costs less than 50 rubles per bottle. If you want to test your home filter in the same way as we did, here is the easiest and cheap way.

So, we dissolved the contents of the vial (50 ml) in 6 liters of water and got a solution with a concentration of approximately 50 mg/l. The resulting dark blue liquid was passed through filters. The results were evaluated visually as follows: if the water is completely transparent, the filter copes well with organic pollutants. If the water at the outlet is blue or blue, respectively, such a filter would also let pesticides through. The darker the blue, the lower the cleaning percentage.

You can judge for yourself from the photo: cleaning is close to 100% - only at Aquaphor. He was the only one who gave out visually clear water. Barrier and Brita have 80-85% each, which, by the way, is more expensive than the rest of the participants combined.

Then they washed the jugs with water from the "blue" and immediately began testing the effectiveness of the same cartridges in the fight against rusty water. For clarity, we used a suspension of iron (III) hydroxide at a concentration of 100 mg/l (for iron). The resulting solution has more than three hundred times the maximum allowable concentration of iron in water.

In this experiment, Brita stood out: water passed through the filter one and a half times faster than through Aquaphor and Barrier. For an ordinary user, such a high “clearing” speed is a big plus. Just scored - and you can already drink. That's just, as it became clear from the experiment, fast does not always mean good!

The results were also evaluated visually. According to the results of the rust test, Aquaphor again became the “winner” - it gave completely clear water at the outlet, that is, it filtered out almost 100% of the suspension. The second place belongs to the “Barrier” (~ 85%), and the most expensive participant in our experiments, Brita (~ 80%), removed the rust from the water worst of all.

These results are visible even without any measurement of concentrations - it's just that the water looks completely different. Such different results for similar (seemingly) filters in terms of design and operation principle surprised us. As I said, initially I used to think that they all work the same way. To find out the reason for such strong differences in the efficiency of water purification, we decided to open the cartridges and study the sorbent. Maybe Aquaphor has more of it or does it have a fundamentally different composition?

We cut the cartridges that participated in the test and examined the contents. Inner world"Barrier" and "Brits" turned out to be identical. Black granules - Activated carbon, gray granules - ion-exchange resin. Brita has smaller granules - hence the high speed and poor quality of mechanical filtration. Despite the fact that the filter is the most expensive, the sorbent in it is the least.

Against the backdrop of the Barrier and Brita crumbling into a shapeless pile, the sorbent from the Aquaphor cartridge keeps invigorating. The granules of coal and resin in this filter have retained their shape Easter cake, and the granules are two times smaller in size than those of Brita and Barrier.

These granules are held together by thin yellow fibers as a single composite. It's kind of like earth in a pot with a plant - if you've ever transplanted flowers, you've seen how the tangle of fine roots holds the soil together.

The fibers, as it turned out, are a special material of Aqualen-2. The manufacturer's website says that this is a unique own development of the Aquaphor Research Institute - a special fiber that (further quote from the site) “selectively absorbs heavy metal ions and allows silver ions to be retained in the sorbent in an active ionic form, and also retains sorbent granules, preventing the formation of channels through which water passes without purification.”

The diagram above (also taken from the Aquaphor website) shows how the sorbent works in different filters. In conventional cartridges, where activated charcoal and resin are packed in a chaotic pile, water forms channels between the granules and passes through them very quickly with little or no cleaning. Aqualen-2 fights the "channel effect" and allows the use of a finer sorbent. The “root system” in the Aquaphor cartridge distributes water over a large area, so that the sorbent has time to retain more pollutants. Clear water in a jug is a direct confirmation of this.

The photo of the disassembled cartridge shows that the blue dye solution did not pass even a third of the sorbent block, while the Barrier and Brita sorbents were completely stained, and at the same time, part of the methylene blue was passed into the container for purified water.

Why do other manufacturers not even try to do something similar, but use the old technology of filling the sorbent in a shapeless pile? In search of additions to the experiment, I again scoured the Internet. At the jugs of "Brita" interesting design, very beautiful creative advertising. It was not possible to find intelligible information on the content of the filters. Coal and ion exchange resin are classics that have not changed for more than 30 years. "Barrier" clearly shows the cartridge in a section, but the experiment says that there are also questions about the effectiveness of such a design. "Aquaphor" does not skimp and invests in development. They did not even expect to find a Russian manufacturer's own research institute and investments in know-how worth millions of dollars.

Why, apart from Aquaphor, few people bother with the development of technology - one can only guess. First, it is difficult and expensive. Secondly, it is also a thankless task. With more or less normal tap water, the presence of contamination in it with the naked eye cannot be seen - the solutions of most toxins and pesticides are actually colorless, and not blue, like the dye in our experiment. Rust in such a strong concentration occurs only during accidents or in “morning discharges”. None of the usual buyers of filters will conduct stress tests like ours. That is normal person, like my mother, she will not know about the existence of any differences in the quality of cleaning between "Brita" and "Aquaphor". And in the store on the shelf, all filters are generally the same, and people choose by price, volume and color of the lid. So why do manufacturers spend money on development - is it logical?
However, enough lyrics - let's continue to compare filters.

In general, stationary filters, although more expensive, are better (at least for Russian realities). Readers who have their own housing or rather accommodating landlords are definitely advised to spend money and install a stationary filter, and not expect to get by with a jug. But which sink filter should you choose?

It is unlikely that you will be able to compare stationary filters at home: firstly, it is expensive to buy several different filters, and secondly, it is also quite difficult to mount them.

In order not to waste time installing filters under the sink, we built a tricky “simulation” of a water pipe right in the laboratory. An electric pump pumps water with a pressure of about 3.5 atmospheres from a large tank of raw water to two filters at once. The filtered water is collected in two smaller glass containers.

The participants in the new comparison were two filters that are claimed to remove 100% of bacteria from the water. In the case of microbiological contamination, half-measures are unacceptable: either the filter removes 100% of all bacteria, or it is 100% NOT effective. The thing is that, unlike pesticides, toxins, rust, hardness salts and other pollutants, living organisms reproduce. So even if the filter leaves 0.01% of bacteria in the water, after some time this negligible amount of microorganisms will multiply to a volume of 100%.

So, filters with a “bactericidal” function: in the left corner of the ring “Aquaphor Crystal Eco” with a K7V cartridge (4,950 rubles), in the right corner of the ring there was a “Geyser” with an Aragon-2 cartridge (4,790 rubles).

…………………. THE FURTHER TEXT HAS BEEN CHANGED AFTER POST PUBLISHING …………………

I was forced to change the original text of my post at the request of an employee of the Geyser company.

The comparison gave extremely interesting results and conclusions, collected a lot of comments, questions and clarifications in PM (thanks for your interest!).
But two weeks later, a representative of the Geyser brand came to me in a personal message and accused me of bias and unfair conclusions. And after some discussions, they demanded from me an ultimatum to remove the description of the test results of their filter from my post, threatening otherwise to put legal pressure and achieve the removal of the entire post. Ugly, in general, the situation came out.

In PM, I asked the representative a simple question:
How does Geyser with an Aragon cartridge filter water from bacteria and viruses?

A) mechanical filtration method (simply physically does not let bacteria through)? If so, why do particles as small as 1 micron (the same size for bacteria) pass through the filter in my test?
b) or is it still a chemical filtration method? If so, which substance actively kills bacteria and viruses? After all, we look at point a) particles of 1 micron in size still seep through the filter - our test clearly showed this.

Unfortunately, after a long, several days, personal correspondence, I did not receive answers to these questions from the Geyser representative.

But, in any case, I delete the results of our testing of the Geyser filter with the Aragon cartridge from the post - I don’t want to provoke a conflict.

Nevertheless, I consider it necessary to note that the test results seemed to me (and a large number of readers) worthy of interest. And so I will continue to understand the issue further. And I will think about how to convey unbiased information about the real effectiveness of Geyser filters to interested consumers.

In the meantime, I suggest that you familiarize yourself with the second part of the results of our test - the results of the Aquaphor filter.

…………………. END OF CHANGED FRAGMENT OF THE ORIGINAL POST …………………

We did not dare to dilute dangerous biological pollution, therefore, as a test system, we decided to use a suspension of hematite, a mineral whose particles are comparable in size to the size of bacteria (about 1 micron). A suspension of hematite at a concentration of 0.5 g per liter has a rich carrot color - if the filters do not cut off the particles, we will immediately see this - the water will be yellow.

"Aquaphor" with a K7V cartridge gave clear, clean water. Hematite particles remained in the filter - the same fate would have awaited bacteria.

The Aquaphor IVF test report is included in the device instructions. According to the protocol, due to the use of a hollow fiber membrane, the filter cuts off 100% of bacteria. The manufacturer's website indicates that the membrane retains the smallest particles ranging in size from 0.1 microns.

conclusions

In the course of our tests, the Aquaphor filters turned out to be the most effective and interesting to study. The domestic manufacturer, quite unexpectedly for us, significantly outperformed its rivals in terms of the quality of water purification: in all tests, its filters produced clean, clear water. As far as we understood the topic, the effect was achieved due to the company's own developments. For example, the patented Aqualen-2 fiber made the filter-jug sorbent an order of magnitude more efficient and extended its service life.

The eminent European brand Brita was genuinely disappointed: it turned out that in the case of filters of this brand, the overpayment goes exclusively for European origin and a loud, well-known name. The Germans managed to save even on cartridge filler, which is why their jug ​​showed the weakest results.
In my kitchen, I eventually installed Aquaphor Crystal ECO. And I took Aquaphor Provence to my parents' dacha. Instead of the Brita they had before...

Pure water without impurities, enriched with minerals is the key to good health and longevity. In order for purified and most useful water to always be in the house, it is recommended to install cleaning and filtering systems. Our ranking of the best water purifiers 2019 will help you make your choice.

Water filtration has been practiced since the dawn of the human era. One of the first methods of purification - carbon filtration - has come down to our days. Russian market cleaning technology is rich in the 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, based on ion-exchange resins. They filter not only iron, but also manganese, which most other systems cannot handle.
• reverse osmosis filters - the most environmentally friendly and most efficient systems. They cope with the removal of all impurities and bacteria, additionally mineralize the water before leaving (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 trap impurities (sorption process).
• aeration filters - water is purified using oxygen in special tanks.
• electric filters - purify water with ozone from all organic and inorganic contaminants oxidized and dissolved in it, however, they are very uneconomical in energy consumption.
• pitcher design filters - the design consists of a tank for raw water, a tank for purified water and a carbon filter.
• cartridge filters - the design consists of several flasks, inside of which there is a 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. Allocate:

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

After you decide on the degree of purification, you should choose filter installation type:

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