A mechanical element + polyphosphate salts. A filtering element of the cold water ensures water purification from mechanical impurities, rust, precipitation. The filtering element contains polyphosphate salts, which, reacting with calcium dissolved in water, modifies the chemical formula of lime and softens water, preventing household appliances from scale formation. Recommended flow: 12 l/min at 2 bar pressure. Maximum flow rate ~ 50 l/min. Resistance to water flow: ~ 20%. The source of purifyable water: up to 20000 litres. Maximum water temperature: 38°C. This is the best water filter for your washing-machine, water boiler or any water heating appliance. Not recommended for drinking water.

Remark: If you need to use water for drinking, install a filter that contains activated choal behind this filtering element.
