Scale Inhibitor Filter: The PHO polyphosphate filter effectively removes calcium and magnesium ions, preventing scale buildup on pipes and heating equipment, reducing scaling and extending equipment lifespan

Efficient Filtration: The filled silica-phosphate beads slowly release protectants that bind with calcium, magnesium, and other hard water ions, preventing scale formation, softening water, and protecting appliances and plumbing from corrosion

Universal Cartridge: Featuring a standard 4.5" x 20" size, the replacement cartridge fits most filter housings and whole house water filter systems on the market. Easy to install and replace, with no additional modifications required
