Kohler Aquifer Double Cartridge Water Filtration System

Enjoy greater peace of mind about the water you drink at home. The Aquifer double-cartridge water filtration system effectively reduces contaminants including lead, mercury, chlorine, and pharmaceuticals in your cold water -- without compromising your faucet's performance. While many other systems use coal-based media filters, the Aquifer filter uses ground-up coconut shells, making it more eco-friendly. Under-sink installation is fast and easy, and the compact Aquifer system fits alongside garbage disposals and household items stored below the sink.
