The Katadyn BeFree 1.0L is a lightweight, collapsible filtered water bottle designed for backpackers, hikers, trail runners, and travelers who need fast, reliable filtration without the bulk. The 0.1 micron EZ-Clean hollow fiber membrane filters out sediment and fine particles from your water sources at a fast 2 L/min flow rate with up to 1,000L total capacity. The bottle itself collapses completely flat when empty, packs into any pocket or side sleeve, and weighs only 2.3 oz so it adds virtually nothing to your pack weight. To drink, simply fill from any stream, lake, spring, or tap and squeeze directly through the filter. No pumping, no waiting, no tablets needed. Maintaining the filter is just as simple: shake or swish the bottle in water to restore full flow. No backflushing tools required and no disassembly. The foldable, BPA-free bottle is compatible with hydration packs, fits standard water bottle pockets, and collapses to almost nothing for storage. Built on nearly a century of water filtration expertise, the BeFree 1.0L is trusted by endurance athletes, backpackers, emergency preparedness planners, and everyday adventurers worldwide. Clean water wherever the trail takes you.
