Laurie M.wrote a review of Hydro Photon Water Bottle Pre-Filter on August 5, 2009
I used this on a river kayak camping trip with a group of friends. It works great, attached perfectly to an old water bottle that I use.
Friends were a little skeptical about the whole filter and steripen process but everyone survived and they were able to party on with no ill effects!
I'm thinking it would be a great addition to a grab and go pack.
