Three stage water filtration system utilizes proprietary Quick-Change cartridge technology that makes filter changes extremely easy and mess free. The system includes one sediment filter cartridge for sand, silt and rust particle reduction, one carbon block for chlorine taste and odor reduction and one UF membrane for particle reduction down to 0.1 microns. The filters are removed with a simple quarter turn and filter heads have built-in check valves that automatically shut off the water during filter removal. Includes complete hardware installation kit and long-reach chrome faucet dispenser to deliver great tasting water. This under counter unit does not require a storage tank.
