    The Tier1 5 micron carbon and polyphosphate whole house softening replacement cartridge uses carbon and polyphosphate media to improve both the taste of your water and its quality by providing a softening filtration to help prevent scale build up. The added benefit of this cartridge is that it offers a more economical option compared to a water softener as it does not require water waste and salt for regeneration and backwash cycles. Polyphosphate is an alternative media to ion exchange resin for turning hard water into softened water because is helps reduce hardness minerals like calcium and magnesium from bonding and forming scale deposits. Enjoy better tasting water and the benefits of softened water with your carbon and polyphosphate water softening cartridge. Tier1 is ready to protect every drop.
