Best water filter reviews
Scientists confirm that 80% of diseases a person gets from drinking poor-quality water. Even seemingly transparent water, without foreign tastes and odors, can conceal in its composition a lot of substances hazardous to health: chlorine, heavy metals, bacteria, viruses, oil products and other harmful impurities. To protect your health, experts recommend using only purified water for drinking, cooking and personal care, and for this you need to install a special filter. Aquaphor experts tell you about what water filters are and how to choose the right filter.
The most popular and affordable type of water purifier, which consists of a plastic container with a handle and a removable filter module. The degree of water purification in the jug is quite high. It depends on a removable module that solves different tasks: water softening, chlorine removal, purification from all types of impurities, destruction of bacteria and viruses. The resource of these modules is about 300 liters, so they need to be changed periodically. Filter jugs are compact and mobile, do not require a connection to the water supply.
These small fixtures, which can be slipped directly onto the faucet or installed next to the sink, are also budget options. Depending on the model and the removable module, the attachments, as well as the jugs, are aimed at achieving different goals in water purification. Such filters reduce water hardness, cleanse it from various impurities, rust and chlorine, and also have a bactericidal effect. The resource of the filter module in the nozzle is from 750 to 4000 liters, depending on the model, the filtration rate is much higher than that of a jug. It is convenient to take such a compact device with you on trips, on business trips, where it is possible to connect to a water tap.
In-line filters with separate tap
Such filters consist of one or more housings that are built into the water supply system and located under the sink. At the same time, a separate tap is brought to the sink for drinking water. Such a system contains multi-stage cleaning: coarse, during which mechanical impurities are removed; thin, retaining the smallest particles; a filter that destroys harmful bacteria; and an iron reducing filter. These water purifiers have a very long resource from 4000 to 15000 liters, a high filtration rate, and the level of purification by such a device is so high that water from any source can be made useful and clean. Such filters have a wide price range – from 2 to 10 thousand rubles. It is necessary to change the filter modules every six months – a year. However, the system requires professional installation.
The most effective method for obtaining purified water. It is installed under the sink, built into the water supply system and also has a separate tap for drinking water. The filter contains three stages of water purification and a special storage tank. The main filtering element of this system is a semi-permeable reverse osmosis membrane. Its pores are so small that only water molecules can pass through, and everything else remains on the other side of the membrane. The result is very high quality purified water, free from excess hardness, iron, sediment, heavy metals, bacteria and viruses. The reverse osmosis membrane needs to be changed every three years, and the post-purification modules – once a year.
However, traditional reverse osmosis filters have a number of significant disadvantages. Firstly, you have to use a storage tank for clean water, which is larger than the filter itself. Secondly, the pressure in the water supply system must be high, at least three and a half atmospheres. Thirdly, a large amount of water is needed to flush the membrane, that is, to get 1 liter of crystal clear drink, you need to drain 10 liters of water into the sewer. And, fourthly, the abundance of control tubes and valves makes the filter very cumbersome.
However, now a new generation water purifier has been developed, which differs from the traditional filter in the automation system and the storage tank of a new type and three times less space in the kitchen.
