Drink clean water! TOP-5 flow filters

The low-cost solution from the east european NGO "Ecosoft" is designed to compete with more expensive flow filters for cleaning tap water. The main trump card of the model is the democratic cost of both the device itself and replaceable cartridges for it.

The filter is designed specifically for water purification from chlorine and organic compounds. In parallel, it cuts off impurities from 5 microns in size and detains heavy metal ions. Filtration of tap water is carried out in three stages: a mechanical cartridge detains large particles, a granular carbon filter removes chlorine and organic impurities, and briquetted activated carbon in the last cartridge cleans and conditions the water.

The kit with the filter includes all the necessary consumables for easy and convenient installation of the device under the sink. Every consumer can cope with its installation. That's just when installing a tap for purified water in the sink, which is embedded in the countertop, in some cases there may not be enough length of the fixing pin to fix the tap.

The owners of the filter leave entirely positive reviews about the quality of tap water filtration. However, the resource of replaceable cartridges in the model is not so great and is 1000 liters. There are also complaints about the inconvenient way of collecting water due to the push-type handle used in the design of the crane. In fact, everything is simple — to ensure a constant stream of water to fill the kettle, it is enough to lift the handle up to the stop.

The filter is designed to work in water supply systems with a pressure from 2 to 5 atm. Therefore, if the water pressure in your apartment is strong enough, it would be useful to get a pressure reducer in order to avoid possible failure of the model and, accordingly, to protect the dwelling from water leaks.

Aquafor flow filter, installed under the sink, provides three stages of purification of tap water. At the first stage, preliminary cleaning is carried out (cartridge K1-03), at the second — deep sorption aftertreatment (module K1-02), and at the third — finishing cleaning and conditioning of drinking water (cartridge K1-07).

In the filter design, a hollow fibre membrane is used, the fibers of which retain the smallest particles of contamination of the order of 0.1 microns in size. It allows you to cut off the penetration of the vast majority of pathogenic microorganisms into drinking water. At the remaining stages, the water completely gets rid of active chlorine, heavy metals and toxic impurities.

To cope with the installation of the filter is within the power of every owner of a drill and an adjustable wrench. The tap of the device crashes into the sink, and through its spout you can quickly get water into the kettle or wash vegetables and fruits under a purified stream of water. "Thank you" for this must be said to the high filtration capacity (2.5 L/min.). In addition to the filtration rate, Aquaphor Crystal Eco has an increased cartridge life — their stated service life provides the possibility of passing through 8000 liters of water.

In some instances of the filter, the approach of the end of the cartridge life may be accompanied by the occurrence of leaks at the junctions of the replaceable modules with the main structure. This is rare, but you should not discount such a nuance. Finally, it should be noted that the filter has an additional modification — Aquaphor Crystal Eco H . It is designed to soften excessively hard tap water.

 

Effective purification of tap water, reverse osmosis, water mineralizer, double tap included.

 

 

The storage tank takes up a lot of space.

 

A model with a tank and a mineralizer from the Geyser company purifies water based on the reverse osmosis phenomenon, which provides better filtration at home.

The key component of the filter is the Vontron membrane, the pore size of which is 0.0001 microns. Only water molecules seep through it, and all other contaminants do not settle in the fibers and on the membrane walls thanks to a special protective layer. Water purification takes place at the molecular level with maximum efficiency.

Together with harmful impurities, tap water is also purified from useful minerals. Therefore, the filter is equipped with a mineralizer to saturate drinking water with micronutrients (calcium, magnesium, fluorine, etc.). These useful elements not only have a beneficial effect on the body, but also improve the taste of water. As a result, it becomes possible to get the purest water with a mild taste and useful properties at the exit.

Reverse osmosis filters cannot boast of high performance. The Prestige M Geyser has a filtration rate of only 0.14 L/min. The water tank with a capacity of 7.6 or 12 liters (depending on the specific configuration) is designed to solve the problem. On the one hand, it takes up a lot of space under the sink, and on the other hand, you can use the water in the tank even if the centralized water supply is turned off.

A tap with two handles is supplied with the filter, which allows you to collect purified and mineralized water separately. In the first case, the water can be used for watering plants or filling the humidifier tank, and in the second — as drinking. The model is an excellent option for installation in an apartment, which is able to provide the whole family with clean, tasty and healthy drinking water.

Useful to know. Due to the peculiarities of the operation of water filters with a reverse osmosis system, more than 40% of the water is drained into the sewer along with filtered impurities. But they provide the highest degree of purification — up to 99% elimination of any contamination. Filters with a reverse osmosis system can even be used for desalination of salt water.

Atoll A-560E is designed for installation under the sink and direct connection to the water supply system. The filter purifies water from organic impurities, active chlorine, petroleum products, heavy metal ions and colloidal iron.

Drinking water purification takes place in 5 stages. First, the coarse filter cuts off pollutants from 5 km in size. Then the water enters a cartridge with granular activated carbon, where organic impurities and active chlorine are removed from it. At the next stage, mechanical particles with a size of 1 µm are delayed, after which the main actor is connected — the reverse osmotic membrane. At the finish, the purified water additionally passes through an ultra-fine filter, which guarantees the receipt of the cleanest drinking water.

Filtration by reverse osmosis is carried out carefully and, accordingly, its speed is low. Therefore, a separate tank with a volume of 12 liters is provided for the storage of filtered water. The presence of a reservoir helps to create an autonomous water supply, which can be used, including in case of unplanned water supply outages.

Although Pentek cartridges compatible with the model are quite expensive, nevertheless, their long service life (10000 liters) allows you to save on frequent replacement of filter elements. And in order not to get confused during installation, the cartridges are connected to the filter housing with multicoloured tubes.

Scale on the walls of the kettle or pots when used for cooking filtered water does not remain at all. Well, the high quality of materials in the design of the model allows you not to worry about the occurrence of water leaks. In fact, the high cost of the Atoll A-560E is an additional payment for the build quality and peace of mind of the filter owners.

The design of the flow filter from the well-known South Korean brand RAIFIL uses components from world leaders in the field of water treatment. The model itself offers a 6-step purification of tap water, after which the liquid not only gets rid of impurities, but is also saturated with micronutrients useful for health.

During filtration, all possible impurities, impurities and organic substances are filtered out of the water, and active chlorine is completely removed. And in order for the water to remain tasty and healthy, a built-in mineralizer comes into operation at the last stage of processing. A tap with two regulators leaves the consumer with a choice: mineralized water can be used for drinking, and simply purified water for cooking.

In a minute, the filter is able to pass through only 0.13 liters of water. However, such low performance is characteristic of all models operating on the basis of the reverse osmosis method. In the arsenal of such filters there is a storage tank. In this case, its capacity is 12 liters — water reserves will last for some time even in the event of an emergency shutdown of the water supply.

The design of the RAIFIL Grando 6 includes a built-in pump, which is designed to ensure normal operating pressure for the filter in the event of a decrease in the water pressure at the inlet below the required 2.8 atm. The maximum pressure threshold in this case should not exceed a value of 6 atm. The specified range is fully suitable for ordinary household use of the model.

It is advisable to change the three lower filter elements every six months. The replacement period of the postfilter and mineralizer is 1 year. And most rarely you will have to look for a replacement for the membrane — depending on the operating conditions, it needs to be changed every 2-3 years. By the way, the pre-filter is enclosed in a transparent flask, so you can also visually monitor the condition of the first cartridge for its timely replacement.
