Simply put, this process is the passage of water under pressure through a special semipermeable membrane. It has a “sieve” of pores up to 0.0001 microns (or 0.1 nm), which pass only H2O molecules. Reverse osmosis purifies the water so deeply that useful salts of calcium and magnesium, necessary for the normal functioning of the cardiovascular system and musculoskeletal system, disappear from it. The way out will be a mineralizer, which manufacturers offer to buy together with the filter.

Many people may have the impression that reverse osmosis filters — it’s too expensive, and at home, you can do less expensive means, for example, filter jugs or nozzles on the tap.

Also, the use of reverse osmosis systems is recommended in cases where the composition of the source water is not known, and it is not possible to make a detailed analysis.

How to choose a reverse osmosis filter?

Membrane filters for water purification with reverse osmosis remove particles that are 100 thousand times smaller than the thickness of a human hair (particles up to 0.001 microns). Such deep filtering takes time. So that you do not have to wait for water to get into the kettle or pan, almost all models use a storage tank for clean water.

If the space under the sink is limited, it is better to choose a system with a compact built-in tank for clean water.
In a standard reverse osmosis membrane filter for washing, there is enough water in the tank for a family of 5-6 people. But at any volume of the tank, it is good if it will be filled quickly. Especially if you are preparing dinner for the company of relatives or friends.

If you often cook at home for a large family and like to receive guests-choose a water filter that will accumulate 5 liters of clean water no longer than an hour.
The rate of water intake depends on the design of the reverse osmosis filter and the pressure in the water supply. The higher it is, the faster and more efficient the filter works, and the less water it spends on preparing a liter of clean drinking water. At pressures below 3.5 atmospheres, the classic reverse osmosis filter needs an electric pump to increase the pressure. Otherwise, the filtered water will accumulate in the tank too slowly, and some of the water will constantly leak into the drain.
