Apparatus for filtering contaminants from liquids such as cooking oil is disclosed. A filter assembly comprises an envelope formed of an upper wire mesh filter element and a lower wire mesh filter element joined about their peripheral edges and a porous insert filter member removably contained centrally within the envelope which has a plurality of voids allowing vertical and lateral fluid flow therethrough. The filter assembly is releasably secured in the assembled condition by a fastener which is adapted to be connected to a pump and the fastener has fluid passageways in communication with the lateral flow passages in the porous insert for drawing fluid through the upper and lower filter elements and said insert. The upper and lower filter elements of the envelope are formed of stainless steel mesh and the porous insert filter member is formed of apertured aluminum plate. The filter assembly is suited for use in combination with food cooking apparatus employing cooking oil disposed in a container in which food particles and other particulate matter become deposited and may be used in place of conventional cooking oil filter apparatus. The apparatus is also suitable for use in systems employing a filter powder disbursed in the cooking oil to be filtered.
