User Review: MSR SweetWater Microfilter
Used the filter on an 8-day elk hunt in Idaho. Used it at least 2-3 times/day and had no problems. Can be a bit tricky trying to work everything with only two hands -- need a third at times, but this was not a major issue. Water tasted great and certainly had no ill health effects. Also did not have any clogging problems as I have heard from others.
