The AquaCera CeraMetix-GF Imperial water filter element is the most advanced filter available. The AquaMetix core technology used inside a silver impregnated ceramic micro-filter outer shell provides essentially complete reduction of pathogenic organisms plus the reduction of aluminum, arsenic, cadmium, chloramines, chlorine, fluoride, lead, mercury, nickel, radionuclides, silver, trihalomethanes, and VOC’s.

Imperial filters are 2¾" in diameter. The larger diameter Imperial filters offer about 40% higher flow rates and longer life than the 2" diameter SlimLine filters. These filter elements are for use in gravity filter systems only and should not be used in pressure filtration systems.
