Currently, every resident of an apartment building knows that drinking raw tap water is unsafe for health. The main reason is the sheer amount of hazardous chemicals as well as foreign matter. This is explained by the elementary pollution of pipes and, accordingly, of the water itself. Thus, the use of special filters for water purification is gaining popularity every year. They differ in type and can be used both at work in the office and in a house or apartment.
The main purpose of any filter is maximum water purification. This is especially important for those with kidney disease. The best cleaning systems are filters under the sink. How to choose it, what you need to pay special attention to, what types of models exist - all this will be discussed in this article.

Before purchasing this filter, it is important to find out the exact chemistry of your tap water. After this is done, it is easier to choose exactly the product that will purify the water as efficiently as possible. For example, if the water is too hard, then in this case you need a filter equipped with a membrane, that is, reverse osmosis. These products cannot be called cheap, but hard water must be purified for kidney health. If it turns out that the hardness is not high, then an ion exchange filter will do.
Before purchasing a filter for washing, you need to pay attention to the following aspects - cleaning technology and the presence of a softener:
The article pays special attention to the compilation of the most comprehensive information rating of specialized filters for running water. All data is based on the recommendations of leading experts and professionals in the field, as well as on feedback from buyers and users of these products. Close attention is paid to the ratio of price and quality of goods.
This filter has the most effective cleaning system, additionally softening the water. Thus, it is possible to almost completely get rid of turbidity and achieve perfect transparency. Among the constituent components, the most important role is given to a unique semi-permeable membrane. It is complemented by specialized coal modules. Thanks to this design, it is possible to completely remove any foreign impurities in tap water, the value of which can sometimes reach 0.0005 microns. This includes all types of heavy metals, chlorine compounds, rust, pesticides and nitrates.
Due to this maximum purification, the water becomes tastier, and also it begins to bring more benefits. Once filtered, you can prepare food and drinks even for children of all ages. The tank as part of the design allows you to hold 10 liters at once; there is also a carbon post-filter.
For water purification, the temperature should not be higher than +30 degrees Celsius, if the decision is made to filter exclusively cold water. The appliance is compact and small in size, so it can be easily installed under the sink. A specialized crane departs from the device. The filter easily passes 1.3 liters per minute. There are 4 degrees of cleaning: coarse, medium, fine and simple cleaning from hazardous chemical compounds.
Price: 6200 rubles.
Filters of this model are equipped with a special high pressure pump. Through osmosis, which is part of the structure, the water goes through 3 stages of purification. First, the water must pass through the cartridge, which is made of expanded polypropylene. The size of each cell in it is 5 μm. Due to this structure of the cartridge, foreign particles are retained. The water is then directed through a carbon block, which is made from coconut activated carbon. Here, chlorine and other substances that are unsafe for humans are neutralized. The aroma and taste of the water changes markedly. At the final stage, it passes through another cartridge - CBC. Its basis is pressed carbonic coal. This allows you to additionally rid water of other hazardous impurities.
The storage tank of this device can hold 12 liters, thanks to which it becomes possible to store a supply of filtered water. The design also includes a mineralizer. Its function is to restore the optimal chemical structure of the water consumed for humans.
Price: 13300 rub.
A distinctive feature of the filters of this model is the high quality of their production. They are based on a high-strength and rather dense plastic case, which is equipped with additional stiffeners. This structure of the structure significantly increases the reliability of the device. Another bonus is that the water can be used immediately after connecting the device. The appearance of the filter also attracts: gradual and sliding rotation of the ball valve.
The initial stage of cleaning is carried out during the entry of the water stream. The cartridge has good density and stiffness. The next step is passing through the coal segment, which can always be replaced if required. Here, the water seeps uniformly through the dispenser installed in the cartridge. As practice shows, one such cartridge is quite enough for complete purification of 19 tons of chlorine from water. The final stage of purification takes place due to the installed additional cartridge, which retains in itself all the remains of chemicals that are unsafe for health. It is also worth noting that it is very tough, which makes it very unlikely to be damaged during use.
Price: 9900 rubles.
This device is one of the highest quality filters based on osmosis technology. Water is perfectly cleaned of all harmful substances, passing through multi-stage filtration. This system is based on 3 main modules. First of all, there is a mechanical cleaning from grains of sand, elements of rust and other foreign particles of large and small size. In the next module, the water is enriched with healing ions and gets rid of chlorine, as well as lead and copper. In the third module, PostCarbon comes into play, the purpose of which is to remove the remaining organic matter.
It is worth noting the ease of installation. Optionally, the filter can be under the sink, or on it. The kit does not require additional purchases, and you can use it without restrictions. This filter is very easy to connect. The only thing to consider is when you start using the filter. This can only be done after skipping the first 10 liters of water, which must be drained. Cartridges are of the replaceable type and should be replaced regularly.
Price: 2600 rubles.
This filter belongs to the best quality osmosis type devices. The device is equipped with a tank that can hold 20 liters. This allows the filter to fill a large space under the sink. The filter includes a five-stage purification system. The whole structure is connected directly to the water supply. This all helps to reduce the total amount of iron and chlorine. The water becomes quite soft, and useful mineral compounds are retained in it, since only harmful elements are retained in the filter. If you regularly replace the cartridges and handle the device carefully, then you can use clean water for a long time. About 1.5 liters of water can pass through the filter in one minute, which corresponds to good product performance.
Price: 7200 rubles.
The whole mechanism is quite easy to install, installation is not more difficult than connecting a kitchen tap. But each connecting tube must be carefully connected in the right position. First, there should be no cover on the filter during this process.Secondly, as soon as all modules are ready for use, they must be rinsed well. After that, the filtering sections can have a purifying effect on the water. The ionic cleaning system underlies the structure of this filter, which is quite compact and small in size, which further simplifies its installation. It has been practically established that the device perfectly cleans water from any type of contamination.
If the need arises, you can purchase another water softener module, as it is not included in the kit. The manufacturer notes that each filter cartridge needs to be replaced about once a year, and the softening elements are best replaced after 7 or 8 months. The structure of the device is universal, for this reason, the types of filtering products are presented in a wide variety.
Price: 3700 rubles.
This device is one of the highest quality filters based on osmosis technology. The ease of installation is also worth noting here. The following options are possible: under the sink, or next to it, as well as on the sink itself. The filter has a modern, beautiful look. The structure of the cartridges is made in accordance with the block-modular design. The body is also equipped with stiffeners. The storage tank has a small volume, which is the reason for its compact size.
The rest of the mechanisms come into play under the condition of high water pressure in the central system, this model also depends on the pressure indicators, but in this case one and a half atmospheres will be enough. All this helps to save water when using it. The useful volume of this tank is equal to five liters of filtered water. The average filtration rate is 1.5 to 2 liters per minute.
Price: 7600 rubles.
A particularly thorough mechanical cleaning in comparison with other models distinguishes this device from many others. Filters of these products are able to retain very small elements contained in water, the size of which is from 5 microns. During the production of this movement, a modern technology called "Smart Lock" was applied. It allows the filter not to move from its place, despite the high pressure of water. In addition, the filter works with the special byPass method. Thanks to this, the period of use of the filter is extended many times. The filter element often does not need to be changed, plus, this method does not allow softening the water more than is required. The purpose of the filter is suitable exclusively for central water supply.
All accessories important for a quality installation are included with the filter. The filtration rate can be up to two liters per minute. But if there is a desire to reduce this speed, then this can be easily done using a crane at the inlet to this filter. One cartridge is designed for an average of 10,000 liters. After exceeding this indicator, the cartridge must be replaced. It is also necessary to ensure that the inlet pressure does not exceed 7 atmospheres.
Price: 3600 rubles.
The most modern model of the highest quality, which explains the price of the product. But the unique functions of this filter allow you to purify water almost 100% of all foreign and unsafe substances. The mechanism is designed in such a way that any particles even smaller than 5 microns cannot remain in the water during the cleaning process. The filter cleans from all hazardous chemical compounds, including pesticides with herbicides.
The cycle of water purification involves 4 types of cartridges at the same time - standard, designed for mechanical purification, freeing water from unnecessary hazardous particles. Then a carbon filter made of activated coconut charcoal is installed in the mechanism. At another stage, there is a reverse osmosis membrane, which is produced in Japan. It should be noted that this membrane stands out in its quality compared to other parts of other types of filtering devices. This is followed by an additional carbon filter, which is made on the basis of activated carbon in the form of granules and mineral compounds, designed for additional saturation of water with irreplaceable elements. The filter parts of this model are designed for a long service life. They can be used as needed and replaced once every 2 or 3 years.
Price: 12300 rub.
In terms of performance, this filter takes the leading place. It is also worth considering the fact that its dimensions are very small, which simplifies the already uncomplicated installation under the sink, it is also not required to replace the cartridge many times. With a large presence of advantages, its price is quite low. This filter allows you to completely purify water from chlorine, small particles of oil products and other elements hazardous to humans.
The filter includes the most modern type of cartridge Aragon 3 ECO. Thanks to this, it is possible to achieve sorption purification of water and at the same time to additionally enrich it with ions.
Price: 6500 rubles.
Of the existing models of filtering devices, IKAR bears the title of the most excellent filter in terms of quality if we evaluate the indicators of the final purified water. The functions of this device are aimed not only at filtering from all kinds of harmful impurities, but also at improving the composition of water. After filtration, the water "revives", that is, it becomes more mineralized and acquires a negative ORP.
In the mechanism of the filter, the main role is played by two fundamental elements: a reverse osmosis filter, through which water passes through 5 stages of filtration, and an ICAR module (here a special ionizer and also a water mineralizer). If desired, the ph-reactor of this filter can be connected during assembly to raise the pH. The installation works are automatically standardized, and they also include a microprocessor-based control and monitoring unit for the structure of the composition and other parameters of water.
This device is usually placed under the sink. Installation is not cheap, especially when compared with other models, but when calculating the final cost of filtered water corresponding to the quality of Lake Baikal, the price will be 2 rubles per 1 liter. These filters have been produced in series since 1997. The installation has received the most prestigious world awards.
Price: 19,500 rubles.
This article has paid close attention to each filter model. Many devices are similar in function and mechanism of action, but some filters better rid water of foreign impurities, while others are aimed at removing chlorine from water. To select the most optimal model, you need to analyze the properties of tap water. In the comments, you can leave additional observations and practical experience.
