“…trips where I expect poor, dirty water, I prefer a pre-filter and/or filter and/or Micropur approach to the Steripen.”

Yep, that’s the downside of UV; I might be able to sterilize tannin water (up to clarity of lemon aid), but psychologically I can’t drink it.

“It never ceases to amaze me that people will take untested equipment such as tents, stoves, GPS units and, yes, Steripens into the field; have them fail due to ignorance and then come back and complain about the gear while forgetting their contribution to the mess.”

I don’t know why that made me laugh, but +1!

Thanx,
