Randy T.wrote a review of MSR MiniWorks EX Water Filter on September 8, 2011
I have been doing backcountry excursions for over twenty years. I have always strove for light weight and bombproof gear. After a week of dehydration because my friends PUR died from silt on the second day of a canyon trip, I bought the MiniWorks. It is a bit heavier, but the weight:safety ratio is a no brainer. I cleaned this thing so much that it is ready for a new filter (8 years!). I now use an MSR Hyperflow for weekend trips for the weight. However, when I head to Alaska, Canada, and backcountry trips longer than two days, I take my faithful MiniWorks.
