Carbon (GAC) Water Filter Replacement Cartridge with Polyphospate

• GAC filtration
• Polyphosphate filled to prevent scale accumulation
• Protects plumbing system metals from acid water corrosion
• Change every 4 - 6 months
• Significantly extends the life of all water using appliances from the adverse impact of acidic and hard water conditions

The filter cartridge is half filled with polyphosphate spheres which provide the essential protection to both tankless and traditional hot water tank systems as well as RO Systems. This ingredient reacts with naturally occurring calcium bicarbonates in the water supply to form a thin, tight, non-corrosive, passivating film on pipe walls. This film is almost like a glass coating, separating the water from the metal plumbing / hot water system.
