BeFree AC Bottle 0,7 L Smoke

The Katadyn BeFree AC Bottle 0,7 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 Bottle 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 bottle can be squeezed to support water flow – faster hydration with less effort. The textured exterior keeps grip secure on the move. 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. 93 g, fits any standard bottle pocket or bike cage.

Pro tip: Never let the filter freeze – hollow fibre cracks when frozen. On cold nights, keep it in your pack or sleeping bag.
