The BeFree Gravity 3.0L weighs just 192 grams and uses gravity to purify up to 2 liters of clean drinking water per minute. The handling of the water filter is particularly easy: all you need to 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 bacteria, cysts and sediment with its pore size of 0.1 micron (0.0001 mm).
The capacity of the filter is up to 1000L, depending on the water quality.
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.
