Product Details

Lightweight and portable for on-the-go adventures, the Katadyn Gravity BeFree Water Filtration Systems use gravity to purify up to two liters of clean drinking water per minute. Fill it up and hang it up. It's that simple.
  • The filter pore size of 0.1 microns (0.0001 mm) filters out bacteria, cysts and sediment.
  • Ultra-durable Hydrapak® is BPA and PVC free for a guilt-free drinking experience.
  • Wide, 43mm mouth opening allows for easy filling from any water source.
  • The 3L BeFree features an integrated bail handle on the nozzle to simplify filling.
  • Carry strap comes in handy on the walk to the water source.
  • Once full, hang the filter from a tree (or just hold it up).
  • EZ-Clean membrane makes cleaning and caring for the filter easy. Simply shake, swish and enjoy the reusable filter for a long time.
  • Filter capacity is tested up to 1,000 liters dependent upon water quality.
  • When you need a replacement, the Katadyn EZClean Membrane Filter Cartridge fits all BeFree filter products (item #: 70874.01).
