Abstract: A rechargeable filter assembly for removal of contaminants from liquids of all types, particularly dry cleaning solvents comprising three nested and spaced apart concentric perforated metal cylinders defining an inner cavity and an outer cavity held in spatial relationship by a base plate and removable lid. With the lid and outer perforated cylinder (exterior shell) removed, a removable and disposable filter unit may be placed within the outer cavity and similar, or different, filter medium may be placed within the inner cavity. The gaskets of the filter unit in conjunction with the lid, the base, the conduit, exterior shell and the inner perforated cylinder provide seals which prevent liquids from bypassing the filter unit.
