Effortless Hydration for Fast-Paced Wilderness Travel

The Katadyn BeFree 1.0L Microfilter is a high-performance, ultralight water filtration system designed for the minimalist explorer. Combining a 1.0-liter collapsible Hydrapak® flask with a 0.1-micron hollow fiber filter, this system allows you to drink safely from streams, lakes, and rivers without the weight or bulk of traditional pump filters. The EZ-Clean Membrane™ is engineered to remove 99.9999% of bacteria and 99.9% of protozoa (such as Giardia and Cryptosporidium), meeting stringent EPA standards for microbiological water purifiers.

The BeFree stands out for its exceptional flow rate of up to 2 liters per minute, providing nearly instant hydration when you need it most. Maintenance is uniquely simple; there is no need for backflushing syringes or specialized tools—simply shake or swish the membrane in water to clear away debris and maintain peak performance. When empty, the durable, BPA-free flask rolls up into a tiny profile that fits easily into a running vest pocket, hip belt, or emergency kit, making it the ultimate companion for trail running, thru-hiking, and international travel.
