Abstract
A water filtering and purifying apparatus made according to the present invention comprises a water filtering and purifying apparatus for filtering and purifying water as it is ejected from a container at low gauge pressures generated by manually squeezing the container. The water filtering apparatus includes a cover for attaching to the container wherein the cover has a pressure responsive venting system for allowing air into the container while substantially preventing air and water contained in the container from escaping. A water filtration and purifying system is contained within the container and the filtration and purifying system comprises a replaceable pleated filter connected to a purifying cartridge.
