ABSTRACT:
A filter for a conventional water jug having a valved tap near the bottom of its cylindrical side wall comprises a pan-like case member that seats in the bottom of the jug and has a filter cartridge removably sealed across its open top. An aperture in the axially short cylindrical side wall of the case member communicates its interior with the inwardly projecting tubular tap inlet. A radially projecting tubular collar on the case member cooperates with an O-ring to provide a seal between the interior of the case member and the tap inlet. A tacky, water-insoluble adhesive area on the underside of the bottom wall of the case member secures it to the bottom wall of a jug. The filter cartridge can comprise blow molded shell halves, filter paper discs, and activated charcoal confined between the discs.
