Restore Your System to Peak Performance

The Katadyn BeFree Replacement Cartridge is the core component of the BeFree filtration system, allowing you to maintain safe and fast hydration without replacing your entire kit. Featuring the innovative EZ-Clean Membrane™, this hollow fiber filter utilizes 0.1-micron technology to effectively remove 99.9999% of bacteria and 99.9% of protozoa, including Giardia and Cryptosporidium. Whether your current filter has reached its 1,000-liter capacity or has become slowed by heavy sediment, this genuine replacement ensures your water remains clean and safe to drink.

One of the standout features of this cartridge is its ultra-fast flow rate, allowing you to process up to 2 liters of water per minute. Maintenance is simple and tool-free; the membrane can be cleaned in the field by simply shaking or swishing it in clean water to dislodge debris. Designed with a universal 42mm thread, it is perfectly compatible with all Katadyn BeFree collapsible flasks (0.6L, 1.0L, and 3.0L) as well as HydraPak® flasks using the same interface. This replacement cartridge is an essential item for long-distance hikers and international travelers to keep in their repair kit.
