Abstract
A filter apparatus includes a cylindrical reservoir with a pistol grip handle. A conical funnel is releasably mounted on the reservoir by quick release threads. A plurality of radially extending support ribs within the funnel support a porous filter disk secured between the reservoir and the funnel. A depending annular seal ring on the reservoir defines a sealing edge which engages the filter disk and seals it against a seal surface and seat on the interior surface of the funnel.
