Description
Poly Guard Crystal Cartridge PCC1 is a 10 x 2 1/2 inch replacement cartridge made with hexametaphosphate crystal. It is designed to treat hard water and low levels of iron without a water softener by slowly dissolving food grade crystals into the water supply. This helps reduce scale buildup, rust staining, and corrosion while protecting plumbing and water-using appliances. One cartridge lasts up to six months and treats up to 30,000 gallons. It is NSF/ANSI Standard 60 certified for drinking water additives.
