ABSTRACT:
A point-of-use filtering and water treating kit includes a container, a plurality of membrane-type filter elements and a filter basket to support the filter elements during use. The filter elements are contained within a reclosable package that is fitted within the container during storage. At least one ladle or other drinking cup is also contained within the container to provide a complete assembly for producing potable water. In use, the package containing the filter elements is removed from the container and a single filter element is placed in the filter basket. The filter basket is nested in the top end of the container and the water to be filtered is poured through the filter element. The filtered and purified water is collected within the container. In one embodiment, the filter elements contain a purifying agent, disinfectant or antimicrobial agent impregnated within the filter element to treat the water as the water is being filtered.
