Product detailed description

Big Blue 20" HA cartridge with polyphosphate crystals against limescale. Not for drinking water. The HA cartridge with polyphosphate crystals is used to protect water heating appliances (boilers, washing machines, instantaneous water heaters, etc.) from limescale build-up. Polyphosphates act on the appliance's internal metal surface, forming a protective film that insulates and protects the surface against corrosion. Household use: protection of water pipes, taps, showers, washing machines, water heaters. Technical use: protection of heating systems, heat exchangers, reverse osmosis units, protection of industrial water systems and other installations. Service life: 3–6 months. Maintenance: none. We recommend using a mechanical pre-filter to protect the cartridge. Designed for 20" MASTER Big Blue filter housings.
