Abstract
Water treatment apparatus includes a two-piece housing and a stack of discrete filtering layers disposed within the housing including a layer of silver impregnated carbon, a layer of pentavalent iodine impregnated resins and at least one layer of a mixed bed activated resin. The apparatus is designed so that no water pressure need be applied to force the water through the apparatus, as gravity pulls the water down through the filtering layers.
