An ideal filtration solution for trail runners, fast packers, and ounce-counting hikers and backpackers, the Katadyn BeFree 0.6L Microfilter marries a microfilter to a flexible drinking flask to provide immediately safe, drinkable water.

Eliminating the need for hoses or separate containers, the system integrates a 0.1 micron microfilter directly into the cap to remove bacteria and cysts, including Giardia and Cryptosporidium. No pumping is required and there's no need to allow time for purification to occur. Simply remove the cap and dip the flexible, BPA-free 0.6L Hydrapak Flask into your water source, screw on the cap, squeeze the bottle, and drink from the “stay clean” nozzle. The filter’s hollow fiber EZ-Clean Membrane can be easily cleaned at home without the need for backflushing, brushes, or other cleaning tools.

The collapsible design of the drinking flask makes the microfilter perfectly suited for the pockets on standard backpacks, running vests, or even cycling jerseys and the entire system weighs in at just 2 ounces! A wide mouth opening on the flask makes it easy to fill, empty, and clean.

Note: The EZ-Clean Membrane has a capacity of up to 1,000 liters, depending on water quality and the EZ-Clean Membrane Replacement Element (sold separately) can be purchased to extend the life of the system beyond that point.
