The Aquafier® multi-stage carbon filtration drinking water system use advanced technology for effective water treatment at the point-of-use. Each Aquafier® equipped with the Faucet SmartapTM Water Flow Monitor indicates filter cartridge status by measuring the volume of water that is dispensed through the system. A green light indicates that the drinking water system is functioning normally. A yellow light indicates that the filters are nearing useful capacity and should be replaced. A patented one piece, injection molded manifold reduces several external fittings where leaks can occur. The Aquafier® systems are rated for effectively reducing turbidity and filterable cysts, including cryptosporidium and giadia. Chemical Reduction performance includes 1750 gallons of Volatile Organic Chemicals (VOC) reduction and 1750 gallons of lead and chlorine reduction when used with the monitor. The Aquafier® drinking water system is backed by a limited two year warranty.
