Limescale Whole House Filter

PCC Series Filter Cartridges contain hexametaphosphate that dissolves slowly in water to inhibit scale and rust build-up.

Hexametaphosphate crystals help prevent lime and scale deposits Effective for treating corrosion and iron problems 

Scale: Hardness particles are kept separated so they cannot precipitate and form deposits when heated; maximum hardness 15 gpg


Corrosion: A protective coating is formed on all metal surfaces, safeguarding against acidity/alkalinity, hardness, chloride and other factors which effect the corrosion of water equipment and pipes; pH range 6.5-9.0


Iron: Dissolved iron, up to 1 ppm, is kept suspended in solution (sequestered), preventing dissolved iron from precipitating, which would cause staining and discoloration
