The Katadyn Gravity BeFree 3L filter by Katadyn weighs just 192g and uses gravity to purify up to 2 liters per minute.

The handling of the water filter is particularly easy: all you do is fill the flexible BPA and PVC free Hydrapak hydration pack with water. The water passes through a 0.1 micron hollow fiber filter which reliably removes any harmful elements. The integrated handle makes filling easier and the carrying strap enables you to transport a full filter back to your camp without any problems, where it can be hung in a neighbouring tree.

The integrated bail handle on the nozzle simplifies filling. The practical carry strap makes fetching water from a river easier and the filter can be hung on a nearby tree once full.

Easily clean the EZ-Clean MembraneTM by simply shaking or swishing the filter in the water. No backflushing or tools necessary.
