The 1 micron carbon and polyphosphate water softening replacement cartridge by Tier1 provides water softening treatment without the hassle of installing a softening system. This filter cartridge uses polyphosphate as part of its filtering media to change how the calcium and iron react in your water. By preventing these and other hardness minerals from bonding together and forming scale build up you can help protect your water using appliances and piping from inefficiencies and corrosion. The benefit of a water softening cartridge is it does not require wasteful regeneration and backwash water use and provides softened water without the need for expensive replacement salt as well. Let Tier1 provide for your water softening needs and enjoy better tasting water in every glass.
