Used this over the weekend with my All Clear. I like the All Clear, but unfortunately when I plunged the bottle into an icy stream the filter clogged and would not let much water in. My guess is that it froze and would not let water pass. What I had to do is use another bottle to get water from the stream, then dump it through this filter into the All Clear, then dump the water into my reservoir.
