AF-1110 is 10-Stage Alkaline Mineral Filter Cartridge. In this Countertop Replacement Filter Cartridge, water passes through 10 media stages to remove contaminants, ionize and re-mineralize before it ends up inside your glass, cooking or coffee pot. In addition to making water cleaner by removing contaminants, the filter eliminates unpleasant odors, increases water alkalinity, reduces ORP (Oxidant Reduction Potential), and adds minerals, making the water more anti-oxidizing and healthier. The ionized water allows maximum mineralization and alkalization. Anti-oxidants help absorb free radicals in the body that lead to aging and diseases. Alkaline water with reduced ORP (read our blog to know more about ORP) hydrates you even better.
