The set consists of three cartridges providing three-stage water purification:
I degree - the cartridge filters are the made foam polypropylene with a density of fibers to 20 microns (removes a deposit, the suspended particles and mechanical pollution);
II degree - cartridge combined action СТО -10 improves the taste and smell of water.
III degree - the cartridge filters are the made foam polypropylene with a density of fibers to 5 microns (removes residual sediment, suspended particles and mechanical contamination).
The sizes of each replaceable cartridge - PP-10-20m: length - 25 cm, diameter - 58 mm; СТО-10: length - 25 cm, diameter - 58 mm; PP-10-5m: length - 25 cm, diameter - 58
