Katadyn BeFree Gravity 3L water purifier

BeFree Gravity 3L weighs only 192 grams and uses gravity to clean up to 2 liters of clean drinking water per minute. Handling the water filter is particularly easy: all you have to do is fill the flexible BPA- and PVC-free HydrapakR beverage container with water. The water passes through a 0.1 micron hollow fiber filter that reliably removes bacteria, cysts and sediment with a 0.1 micron (0.0001 mm) pore size.

The capacity of the filter is up to 1000 liters depending on the water quality. The practical carrying strap makes it easier to fetch water from the river, and the filter can be hung from a nearby tree when it is full.

Clean the EZ-Clean MembraneTM easily by shaking or waving the filter in water.
