Reliable, Easy, Doesn't affect taste
Review by: climbingaggie03, 2008-02-11
I used the Steri-pen for a week in the boundary waters with a group. I treated about 5 gallons a day (20 liters) and didn't have any problems. I also used it in yosemite on snake dike so I could carry less water. It has worked flawlessly for me. I do highly recommend the prefilter and I recommend using lithium batteries. Normally I use rechargeable batteries for shorter trips, but for my week in the boundary waters, I used lithium batteries and they didn't start to die til the last day.
My favorite benefits of the steripen are that it doesn't affect the taste of the water at all, it's fast (about 90 seconds), there's no pumping, and it's pretty light.
I carry iodine or chlorine dioxide as a back up and I carry a spare set of batteries, with that, I don't think you can go wrong.
