ABSTRACT:
A portable water purifier having a filter housing adapted to contain a replaceable filter assembly to which filter housing is releasably attached an unfiltered water chamber with a pressurizing pump located on the top thereof. A cup member is releasably attached to the unfiltered water chamber covering the pressurizing pump and a cap member is releasably attached beneath the filter housing when the portable water purifier is in its storage mode. When the portable water purifier is in its use mode, the cap is removed from the base of the filter housing and attached to the bottom of the cup and the cup is removed from its position covering the pressurizing pump and attached to the filter housing at the position where the cap was attached. Water to be filtered is placed in the unfiltered water chamber when it is disengaged from the filter housing and after reattachment thereto the pressurizing pump is manually operated to create pressure in the unfiltered water chamber forcing the unfiltered water through the filter and into the cup.
