ABSTRACT:
A reusable replacement filter includes a folded elongated filter element. The filter has a cup shaped member which includes a base element. The cup shaped member has a continuous side wall extending upwardly from the periphery of the base element. The cup shaped member has an open end. A plurality of longitudinally disposed rib elements are disposed along opposed portions of the side wall. A removable ring is juxtaposed to the open end of the side wall. The ring has a plurality of fingers which extend axially in an offset complimentary fashion to the rib elements. The ring and cup have means for telescopically engaging the ring to the cup. A removable cap closes the open end of the cup member. The cap and cup each have an aperture for communicating with the exterior of the filter. The apertures allow a fluid to be passed through and cleaned by the filter element.
