Everpure under-counter water filtration systems are anything but standard. Cartridges are made with seamless, polymer-lined aluminum—not plastic, like other filtration systems. The sanitary quick-change cartridge design makes cartridge change out as easy as changing a light bulb. On the inside, they're made using Micro-Pure® precoat filtration technology which means six times more filtering power and superior chlorine and particulate reduction. Even the most affordable filtration system will guard against such contaminants as lead, cysts and asbestos.
