    Gravity BeFree 3.0L Microfilter

The 43mm wide-mouth opening makes for easy filling from lake, river, or tap, and the integrated bail handle and carry loop let you hang it while it filters. To clean the filter in the field, simply shake or swish the EZ-Clean Membrane to remove debris.

    A must have!

    I've used it once or twice and have initial impressions

    I used this for a backpacking trip in Escalante and it kept 6 of us hydrated for 3 days. Better than lugging a ton of water!

    Worked Great!

    I've used it once or twice and have initial impressions

    Bought this to take on a backpacking trip into the Wind Rivers and it was amazing to have! Anytime we stopped by a lake or stream we could restock our group of 6's water supply in less than 15 minutes. This made us all a lot more comfortable with not carrying as much water while we were hiking to reduce weight. Its a little difficult to fill up in a lake but with a little practice it becomes easier.

    The BeFree Just got Better!

    I've put it through the wringer

    I love my BeFree and I'm really psyched to have it in a Gravity package now. I can now use one filter for filtering on the go or around camp. Pair this with a HydraPak Seeker for a durable squeeze pump/extra storage.
