Polyphosphate filter

The polyphosphate filter is designed for chemical softening of water. The filter is made of a thin polypropylene mesh that protects equipment (boilers, washing machines, etc.) from corrosion and mechanical dirt larger than 100 microns. Inside the mesh are polyphosphate grains that gradually dissolve in the water (giving the water softness). After some time (depending on the intensity of use) it is necessary to replace the polyphosphate and clean and wash the net.
