John D.wrote a review of Katadyn BeFree 3L Filtration System on December 4, 2018
Familiarity: I've used it several times
This is the water filtration to have. So much easier than the squeeze filtration systems. I was the only member of the last backpacking trip that had this Katadyn, other guys had the squeeze bags. We ended up using the squeeze bags as storage and just hung the katadyn on a tree and refilled it when it was complete.
Well worth the extra dollars.
