AF-1004 - 7-Stage Alkaline, Anti-oxidizing, GAC, KDF Countertop Replacement Filter Cartridge - 2PK

AF-1004 is a 7-Stage Countertop Replacement Cartridge brought to you by Anchor. This improved filter cartridge is designed to give alkaline water with reduced ORP (Oxidant Reduction Potential) making the water more anti-oxidizing. Anti-oxidants help absorb free radicals in the body that lead to aging and diseases. Alkaline water with reduced ORP hydrates you even better.

With Anchor water filters there are no more unpleasant odors and no chlorine taste, just clean refreshing water. Water from Anchor filters is also great for use in making coffee and tea, and cooking.

All of Anchor water filters feature National Safety Foundation (NSF) certified filter media.
