Consider the advantages and disadvantages of different types.

Filter jug

Structure: jug shaped container of the cleaning cartridge in the upper portion. The water passes through the cartridge and into the container.

      • Accommodation: small size jar, put in any convenient location.

Cartridge filter jug ​​should be constantly in the water. The quality of cleaning sharply reduced if to keep him dry for several days.

      • greater productivity.


      • difficulty in installation;
      • high price;

      • restriction on the installation site.


flow filters are selected, if significant water pollution and / or water consumption is great.

To clean a very dirty water put the main pre-filter. It purifies water from mechanical impurities, sand, clay particles. Install not only reverse osmosis system. It is recommended to put it in front of devices, which are sensitive to water quality. For example, washing machines, dishwashers. Buying a pre-filter will reduce costs for the repair of household appliances.

Attachment on the crane

The capacity of the cartridge is connected to the tap through the nozzle. After cleaning quality are close to pitchers type, but it is more convenient to use. Some models have a switch that lets the water in the filter bypass.
