Q & A

AF-3700 - 7-Stage Countertop Filter comes with the improved 7-Stage Alkaline Filter Cartridge. In this Countertop Water Filter, water passes through 7 filtering media stages to remove contaminants and ionize before it ends up inside your glass, cooking or coffee pot.

The attractively designed unit sits right on your counter top and completes the filtration process automatically, so you can just dispense the water you need and enjoy its refreshing taste.

In addition to making water cleaner, the filter eliminates unpleasant odors, increases water alkalinity, and reduces 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. As a result, the water in your glass helps contribute to a healthier you.

Note: This filter does NOT reduce TDS/PPM

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