USM Series submicron pleated filters offer efficiencies comparable to membrane filtration, but at low press drop, with high flow rates and high loading capacity. These cartridges work equally well in fresh, brackish or saltwater. They are made using a proprietary electroadsorptive media technology that is capable of removing submicron pathogens and inorganic contaminants though electro-adhesion and ion exchange. These filters are offered in ODs of 2.5 and 4.5 in. and lengths of 5 to 40 in.
