The BeFree 1L is designed for fast, on-the-go water filtration during activities like hiking, trail running, backpacking, cycling, and international travel. It allows you to collect and safely drink water from natural sources by removing harmful bacteria, protozoa, and sediment.

Using a 0.1 micron EZ-Clean Membrane, the filter removes: 99.9999% of bacteria (e.g. Klebsiella terrigena), 99.9% of protozoan cysts (e.g. Giardia and Cryptosporidium). *It does not remove viruses or chemical contaminants, so it’s best used in environments where biological pathogens are the primary concern.

The flexible flask is made from high-quality materials but should be handled with care. Some users report that pinholes can develop over time, especially with rough use. Proper storage and careful handling will maximise lifespan.
