Basecamp Gravity Water Filter

A gravity-fed filter system that produces clean water for a group without pumping. Hang the 6-liter dirty reservoir, and the hollow-fiber element filters into the clean bag at roughly 1.5 liters per minute. The element is rated for up to 1,500 gallons and backflushes in seconds. Packed weight is 11 oz. Best for basecamps and family trips.
