Water filters

Thanks to inventions, namely filtration, any liquid is purified. During filtration, water passes through stages of purification, the quality of purification depends on the number of stages.

The first stage – mechanical filtration – removes particles of debris and visually makes the water cleaner. Further, the chemical composition changes, a device equipped with an ion-exchange cartridge copes with this task – heavy substances, such as manganese, lead, are retained.

A liquid that can be consumed without harm to health must undergo another purification through a carbon cartridge – it is cleared of chlorine, an unpleasant odor is neutralized. When the three stages are passed, the water is considered safe.

Types and characteristics of water filters

The main part of cleaning devices are cartridges. Each type and model is designed for its own life.

They are divided into types with corresponding functions:

  • Mechanical: consists of polypropylene; removes sand, rust, mechanical suspensions.
  • Coal: consists of activated (pressed) carbon; removes organic and inorganic substances, eliminates unpleasant odor, liquid color.
  • Softening: composed of Na-cationic resin, removes heavy metals from water.
  • Iron-removing: consists of 2 backfills, which include calcite; removes hydrogen sulfide, improves pH, eliminates metallic taste and odor.


filter pitcher

filter jug: distinguished by its simplicity and budget price. It has a carbon cartridge. Effectively copes with its purpose, but in operation the cartridge is designed for cleaning 500 liters. Two types of cartridges are produced: universal, specialized. Specialized – equipped with additional functions that soften the liquid, add fluorine, remove excess iron.

Attachment on the crane: Equipped with carbon cartridge. When using this type of filter, the pressure should be 2-3 l / h, it cannot cope with a large flow of water.

Standing separately: Installation consists only in connecting the filter to the water supply using a flexible hose. The maximum number of steps in the cartridge is with two degrees of purification.

Standard – polypropylene, activated carbon, 10 inch cartridge will last for 6 months, or 4 tons of water.

There are models that are installed not only next to the sink, but also on the wall. Also, some have an indicator that indicates the need to change the cartridge.

The change should be made 1 time in 4-5 months. Although this type is connected directly to the water supply, it is possible to turn on (turn off) filtration using adapters – you do not need to disconnect the hose every time.

under the sink: Connect directly to the water supply. Washing filters purify water more efficiently, standard equipment 3 cartridges – cleaning methods change by installing the required cartridge, but the first stage of cleaning is always mechanical. Copes with any contamination, which is not affected by the speed of the water flow. Change of cartridges – depends on the selected type of filters.

Trunk: installed directly on the main pipe, which supplies water at the entrance to the apartment or room, that is, in front of the plumbing units. Are established, both on cold, and hot water.

Main filters not only purify drinking liquid, but also save plumbing, extending the life of household appliances connected to the central water supply – dishwashers, washing machines.


prefilter: installed on a water pipe, intended for cleaning and protecting household appliances from mechanical debris. The design consists of a fine-mesh mesh, some models are made with protection against water hammer. During operation, periodic flushing is required.

Purifier (cooler): a stand-alone device cleans and heats or cools drinking water to the required temperature. Models differ in size, appearance, functions. The main direction of such devices is work at enterprises, in offices.

The advantage is not only an increase in quality and taste, but also functions that allow you to heat and cool the liquid. The quality of the liquid filtered by the cooler is superior to bottled water.


Tourist: Designed for hiking, traveling, trip. The main purpose is to clean the liquid from any container, which ensures reliable and high-quality use in difficult conditions.

Nano filters: developed on the basis of nanotechnology, equipped with a semi-permeable membrane, the pores of which are close in size to the size of a water molecule – traps all impurities.

The functions of the filters depend on the possibilities that we recommend paying attention to when choosing:

  • Reverse osmosis is a process in which, with the help of pressure, liquid through a unidirectional membrane moves from a concentrated composition of water with impurities to a low-concentration one. That is, the membrane works as a filter valve, passing water in one direction, retaining impurities, then impurities are discharged into the sewer.
  • No reverse osmosis.
  • Capillary membrane: devices with this function are installed mainly under the sink. There are different purification stages with capillary membranes. The basis is an ultrafiltration membrane consisting of capillary tubes, the main purpose of stonecrop from mechanical debris and bacteria, at the same time, such cleaning retains the mineral composition.

    Attention, this type is for fine water purification, if the liquid is heavily polluted and needs a coarse type of purification, it is required to install pre-filters.

  • Mineralization of water is a necessary and useful process. The main task of mineralization is to make the liquid useful and palatable. The mineralization system is mainly provided on reverse osmosis filters. Since the liquid passing through the membrane is devoid of minerals. Manufacturers have provided such an opportunity that after cleaning the water is not only drinkable, but also useful.
  • UV cleaning is used not only in apartments, but also in wells and wells, as it destroys microbes and bacteria. This method works without auxiliary reagents – it ensures safety and improves water quality, does not change the chemical and physical composition – they are installed for the final stage of purification, it is not recommended to use one of the above filters without preliminary filtration.
  • Cooling and heating water: filter models that provide cooling and / or heating of water. This function is primarily common with the purifier, but there are also multifunctional filters that are equipped with this system.
  • Cartridge replacement indicator – indicates the need to replace the cartridge.

    The consumer does not always monitor the service life, so there is a concern in the use of low-quality water.

  • The faucet in the kit is provided for filters that are installed under the sink, which saves unnecessary costs when installing them, since different faucet models do not have suitable connectors.
  • A pump (pump) is provided to increase the pressure. Since for some filters there is not enough pressure supplied from the central water supply, and without them the device cannot function normally.


The direct purpose of filters is water purification. Filters are used for cleaning, not only drinking, but also household liquids.

Devices that allow you to purify water for any purpose are installed on water pipes. Thus, all the liquid entering the apartment or room is purified.

Devices that are used for hot water are made of more durable materials and are resistant to high temperatures.

There are degrees of purification that allow you to get rid of:

  • active chlorine.
  • Finola.
  • pesticides.
  • Nitrates.
  • Cadmium.
  • Oil products.
  • organic impurities.
  • Colloidal iron.
  • heavy metal ions.

The filters also differ in connection sizes: ½”, 1”, ¾”.

How to choose a water filter


When choosing water filters, determine with what degree of pollution the unit will work. How much purified water is required per hour.

The material from which the device is made is an important element, since it comes into contact with drinking liquid. The characteristics of the units indicate the operating pressure range with which it copes, so you must know what water pressure is supplied from the central water supply.

The volumes that the filter can handle are important, so costs are taken into account, since a small device will not cope with a large volume of liquid.

Each device contains cartridges that have a different wear life.

Pay attention to the presence in the water you use:

  • Metallic taste.
  • Scale.
  • Traces on silverware.
  • Smell.
  • Sediment.

Which is better


A two-person family living in areas where water does not require deep purification will get by with pitcher filters, faucet attachments and free-standing wash filters. These species cope with a small amount of water and pollution. Systems of such a plan do not require complex installations, are easy to use, and are affordable.

But for cleaning with serious pollution, powerful units are required. The system for washing and reverse osmosis provide deep cleansing. Handles large volumes of liquid – suitable for large families, especially with small children, as it copes with pollution (sand, rust,) and bacteria.

The devices are easy to use, as they do not take up much space. They are equipped with 3 degrees of cleaning depending on the manufacturer’s model, different types of cartridges are used, which makes it possible to choose the device according to the needs of the consumer.

Devices with a reverse osmosis system effectively and efficiently purify the liquid, but you should pay attention to the pressure that is inherent in the plumbing system.

These models require high pressure. It should be noted that when cleaning with this device, useful minerals disappear, so make sure that the filter is equipped with a mineralizer.

Ultrafilters do an excellent job of their task, just like devices with a reverse osmosis system, they get rid of all contaminants, bacteria and viruses, after cleaning the mineral composition of the liquid remains normal.



Before using the device, it is recommended to thoroughly wash all surfaces, preferably with soapy water, then rinse with running water and dry.

The cartridge itself must be immersed in water for 20 minutes, and then installed in the device. Then you need to pass the liquid through the filter. The subsequent filtered water can already be consumed.

Please note that devices designed to filter cold water cannot tolerate high temperatures. If the unit is not equipped with a cartridge replacement indicator, it is necessary to monitor the operating life and timely replacement is required. At a break in use, it is necessary to repeat the washing procedure.

It is necessary to monitor the integrity of the cartridge, to avoid mechanical damage. Protect the device from falling. When transporting, the device must be placed in a special protective package. Be sure to read the recommendations for using filters from the manufacturer.



The repair warranty only covers breakdowns and defects that are solely the fault of the manufacturer. In order for consumer claims to be accepted, you need to fill out a warranty card, where you need to indicate the date, model, serial number, seller’s stamp.

If there are defects in the product that you purchased, you can make claims under the terms of the article “On Protection of Consumer Rights”.

Also note that the warranty is valid in cases where the consumer complies with all the rules that are prescribed in the instruction manual.

When water leaks, you need to check the four-way valve, clogged elements or low pressure may also be the reasons for this, to eliminate it, you need to replace the cartridges or install an additional pump that increases the pressure accordingly.

Another problem is the lack of water, which must come from a tap. The reasons for this may be low pressure, clogging of the membrane, low temperature (working 4˚C-40˚C). In order to fix this, you need to install a pump that increases the pressure or replace the membrane.

If a sufficient amount of purified liquid is not drawn into the vessel, it is necessary to replace the pre-filter, membrane or flow restrictor.

Flushing the valve may also help in this case.

If there is air in the system, the fluid may turn beige, but this problem disappears after 2 weeks of operation of the device.

In the absence of a carbon cartridge, clogged membranes, or improper tubing, the liquid after cleaning acquires a bad taste. This can be corrected by rechecking the tubing connections. Replacing the post-filter and membrane will help.

A clogged water flow restrictor is causing fluid to not flow to the drain, and to fix the problem, the restrictor must be replaced.

With a clogged drain or high pressure, noisy operation may occur, in which case it is necessary to remove the blockage or adjust the pressure.

If the pump does not turn off, enough liquid may not be drawn into the vessel; in case of such a malfunction, the pressure must be adjusted.
