Katadyn BeFree Gravity 3 L Microfilter

  • Product Number: 4973 - 8403353

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 microns (0.0001 mm).


  • Compact and ultralight hollow fiber filter
  • Thanks to gravity water flows without pumping.
  • The outlet hose can be removed with a quick-release valve equipped with auto shut off. That keeps the hose from
  • coming in contact with contaminated water during refilling.
  • The practical carry strap makes fetching water from a river easier and the filter can be hung on a nearby tree
  • once full.
  • The integrated bail handle on the nozzle simplifies filling.
  • Collapsible flask packs small to fit into tight spaces.
  • The Katadyn Gravity BeFreeTM 3.0L removes bacteria, cysts and sediment with its pore size of 0.1 micron
  • (0.0001 mm).
  • Easily clean the EZ-Clean MembraneTM by simply shaking or swishing. No backflushing or tools necessary
