ABSTRACT:
A portable water filtration device includes a liquid-tight filter container and a filtration device mounted in the liquid-tight container. The filtration device includes an inlet opening extending through one of the walls and a first filtration device in liquid transfer connection with the inlet opening operative to receive and filter liquid flowing therethrough. A second filtration device is operative to receive liquid from the first filtration device and further filter the liquid flowing therethrough. The first and second filtration devices are selected from the group including ultraviolet, activated carbon and reverse osmosis filters, and an outlet opening extending through one of the walls then receives the treated water and releases the water from the filtration device. Finally, the liquid-tight filter container is operative to prevent liquid from entering the interior volume thereof thereby preventing contamination of the filtration device from accidental incursion of contaminants.
