Despite the centralized water purification, most of the consumers still prefer to use water passed through the filter. However, you need to be able to properly select a hydraulic filter, in order to avoid health problems in the future.

Clearing water at stations, it can be brought to it only to certain standards, but passing through numerous rusty metal pipes significantly spoils its quality. To eliminate the unpleasant odor, harmful impurities, as well as negative taste and there are water consumer filters.
2
The main minus of small filters is a small cartridge size. Only ten minutes of contact of activated carbon coal with water will be able to derive malicious impurities. The productivity of the average size of the cartridge will be only one hundred grams of purified water in ten minutes. Naturally, such productivity is not particularly tempting.
3
The reserve of small filters is only 300-500 liters, and this is quite small. Trying to filter faster than ten minutes, you will not be able to clean the water from all contaminants, so there will be little from such a filter. Everything else, the cartridges will be replaced monthly. Filters of this type are convenient during country trips, in which quality is important, and not a large volume of water.

Selecting fixed filters, you can clean the water qualitatively. Such devices are directly attached to the plumbing pipe and immediately provide purified water. Such hydrophiltra is customary to connect to a separate crane installed next to the main one. Also, such models have a large resource (about 10,000 liters).

One of the most common types of stationary filters is passive multistage models. The best manufacturers in this area are the company "Geyser" and "Akvafor". Basically, they differ in sizes, reserves and cleaning speed. Usually these products have no more than three stages of filtering, where each functioning on its own programmed technology.

Reverse osmosis filters are highly appreciated. Previously, the devices of this type were operated when converting seawater to drinking. To date, they are most often used in commercial and production purposes. Almost all the water sold in stores is passed through reverse osmosis filters.
7
The principle of operation of reverse osmosis filters is that with the help of a powerful pump, water is passed through a special membrane. The pores of this membrane are so miniature that only water molecules can pass through them. Harmful impurities, without passing through filtration, washed off into the sewer. A large disadvantage in such a system is that the cleaning also does not pass and useful bacteria together with the salts necessary for the human body.
Buying a filter, take into account the ratio of the needs and volumes of the water filter, the quality of cleaning, which it produces and, respectively, the performance of performance. Periodically change the cartridge, since it is contaminated over time, and the result will leave the best after filtration.
