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.
