BeFree AC Filter 1.0 L Slate Blue

The Katadyn BeFree AC Filter 1.0 L does what most filters don’t – it makes water taste good. Most filters remove what makes water unsafe. Activated carbon removes what makes it unpleasant. The BeFree AC Filter does both, in the same bottle, in one squeeze.

The EZ-Clean Membrane™ hollow fibre filter handles the safety side: effective against bacteria, protozoa – including Giardia and Cryptosporidium – and microplastics, at 2 L per minute without pumping or chemicals. The activated carbon stage handles taste: chlorine, odour, chemicals. The result is water that is clean and actually worth drinking, whether from a mountain stream, a fountain, or a city tap.

The SoftFlask™ can be squeezed to support water flow – faster hydration with less effort. When flow slows, just shake or swish in clean water to restore the membrane – no tools, no backflushing required. Hollow fibre cartridge lasts up to 1.000 L; activated carbon up to 200 L – replaceable independently. 76 g, folds into any pocket.

Pro tip: If water flow slows during hiking or trail running, fill the flask with fresh water and shake, or swish the filter in a clean water source. Avoid strong running water, which can damage the membrane. If flow remains slow, check for trapped air by filling, closing, shaking, and squeezing the flask until air passes through. On extended trips, carry a spare EZ-Clean membrane. Never let the filter freeze.
