At the moment when the environmental issue isparticularly acute, and the idea of ​​concern about his health began to take a global scale, blurring national and geographical boundaries, we are increasingly pay attention to the consumption of the products. Particular attention should be water coming into our homes on the water pipes. To improve the quality of such water helps a variety of household filters: water filters under the sink, softening filters and other water.

Devices for purification of drinking water for todayDay gained wide popularity. It has long been no secret that the water in our homes contains a large amount of impurities that are often seen with the naked eye. This may be sand, rust and other impurities, both man-made and natural character. In addition, passing the decontamination process, drinking water coming from the taps in our homes, is saturated with chlorine that does not have a positive effect on the human body. That is why household water filters every day becomes more and more a necessity rather than a luxury.

Criteria for selecting the filter for water

Responding to a question about what kind of water filterchoose, you must be guided by the basic requirements for this type of appliance. There are several requirements. Firstly, the filter must have a device for mitigating the incoming water and its decontamination by special bactericidal additives.

Second, safe materials to be used for manufacturing the filter. They should be not only environmentally friendly, but also to prevent the emergence and reproduction of bacteria.

Third, any household filter should effectively purify water from various contaminants and impurities that must be removed permanently.

Particular attention should be paid to the calculation ofconsumption of clean water per day. As a rule, the average person consumes 2.5-3.5 liters of water per day. It is clear that this figure must be multiplied by the number of family members. Experts recommend choosing the device that will be able to provide clean water per day to reserve a triple.

All water filters - reviews about them and the mainSpecifications can be found on the Internet - must have a health certificate, which is proof not only of their security but also due efficiency. In addition, there must be a certificate that serves as proof of compliance with the filter set to the requirements of this type of instrument.

It should be noted that the effectiveness of the filterdetermined by the degree of purity of the water obtained result. This information must be contained in the pages of the passport of water treatment device. Practice the use of household filters showed that the effective purification of drinking water in our homes, the filters must be multi-functional, combining the function of mechanical filtration, ion exchange and adsorption.

Reference to the best producer

When deciding which water filter is best, it is impossibleignore the manufacturers of household appliances database. At present, specialists do not focus on foreign manufacturers in preference. Modern technologies and high quality materials allow to make domestic products that are not inferior in efficiency of operation of foreign analogues. Moreover, some domestic filter models may exceed foreign "colleagues" due to the fact that especially manufactured to our water, the degree of contamination and other features. All necessary tests prior to product launch, conducted on the water that flows through the water pipes of domestic buildings.

Cost of products - an important aspect of

Of course, water filters - reviewsused models can be heard from their friends - divided and price category. The cost of the product is directly proportional to the degree of functionality and practicality of a particular model. The most budget option will Filters- "pitchers" or special cleaning nozzles on taps. Some are more expensive stationary filters. The most expensive is considered to be the main and membrane household water filters to purify tap water.

Types of water filters

Today decided to allocate a large number of the mostvarious types of household filters. At the heart of their separation by type is the set of criteria: the size, operation, efficiency, cost, capacity, performance characteristics, and others.

Mobile filter to "jug"

Filter- "pitcher" to clean drinking water: a compact hand-held device with the simplest scheme of work

Filter- "pitcher" to clean drinking water: a compact hand-held device with the simplest scheme of work

Such a filter is portable and does not requireconnecting directly to the water supply. Their undoubted advantage is the ability to take the device to the cottage or on the environment. The principle of the filters is extremely simple: water is taken into the purifier, where and filtered through a special module. Such a filter to "pitcher" is quite able to meet the daily need for clean drinking water 1-2 people. Each filter module is designed for about 300 liters of clean, so it made a change, usually once every 2-3 months. Water-purifying devices differ in such volumes. However, in country houses and in the presence of a large family is usually used to filter the flow of water.

Nozzles on the tap

Filter attachment on the crane

The nozzle on the faucet cleanse higher quality water than the filter-pitcher

Filter-tips are moreefficiency than Filters- "pitchers". Outwardly, they are removable device of small size, which is attached to the faucet. Puts it is only when the water treatment is needed, other times it can be stored in a drawer. Attaching a filter to a tap carried out using a small hose.

Coal equipment for water treatment

A special love of consumers won coalwater filter, whose action is based on the property of adsorbing activated carbon. It perfectly absorbs chlorine, pesticides and organic. However, it is worth paying attention to the fact that the life of this filter is about 6-9 months. After this period, the filter may not be water-purifying device, and a breeding ground for bacteria and harmful microorganisms for human health.

carbon filter

Carbon filter for household water treatment adsorbs harmful trace elements, organic matter, chlorine, enriches the composition of the water with silver ions

The carbon filters are often added monoxidesilver or aluminum. Water quality is significantly enhanced when it reacts with these substances fluorine or chlorine in running water. Furthermore, the silver to prevent the rapid growth of bacteria that not only protects human health but also to prolong the life of 2-3 months, the filter itself.

Magnetic water filters

Magnetic filter

Magnetic filter for water purification in domestic environment effectively "traps" solids

Consumers often confuse the magnetic filterwater and a magnetic transducer. They are quite similar in principle of operation, however, are not one and the same device. Thus, the magnetic filter designed to purify water by trapping persistent mechanical impurities. The filter retains all the solid particles that are larger than the size of the filter cells. This type of water treatment equipment contributes to the effective protection of devices such as pumps, heat exchangers.

With regard to magnetic transducers, theirfeature is that under the influence of a magnetic field generated by the permanent magnets, magnesium and calcium salt-forming ions lose their ability to deposits on the surfaces of the sorbent.

Instruments mechanical treatment

Mechanical water filter

Appliance mechanical filter prevents the penetration of water insolubles

Suffice it is widely used mechanicalWater filter for effective protection of the entire water supply system from fouling, which causes premature wear of the equipment and reducing bandwidth pipes. Furthermore, such filters prevent corrosion.

Typically, filter mechanical treatmentmounted directly on the water supply system input that allows you to effectively purify water from impurities that do not suffer dissolution: sand, rust, mud, and other impurities, microorganisms.

That is the minimum size of the particles present in the waterIt determines the type of treatment - there is a thin, ultra-thin and rough treatment. Fine cleaning occurs when the particle size of detainees varies between 0.5-5 m, with particle sizes less than 0.5 micron ultra-clean water occurs. Rough purification is carried out at a particle size of from 5 microns to 500 microns.

Trunk filtration system

Experts note that the main filterWater purification is the best option for the protection of household appliances, for use where water is needed. For water softening line filters can significantly increase the life of the dishwasher or washing machine.

Bulk filter for purification of drinking water

Bulk filter - multifunctional system that performs cleaning and optimizing the quality of water

The type of cartridge defines basicthe main purpose of the filter. This can be a water treatment against various mechanical impurities, improve its taste, reducing the amount of chlorine, iron removal of water and elimination of odors.

Thus filters for softening water,clean it from various contaminants and impurities play an important role in our lives. Not only do they allow to preserve health, but also protect the appliances from hard water, the negative impact on it. Of course, today the choice of filter is quite complex, because the water treatment devices on the market a huge number of different models. However, compliance with a number of requirements and nuances will allow to choose the most effective water filter.
