Hi folks,
This is my small contribution to the forum.
I live in Venezuela a so called "3rd world country" and have several hours of traveling, camping and hiking but this is the first time that I heard about this method. What we use to do is the old time classic of boiling the water fro 10 min. and eve some times adding a drop of chlorine solution, same used to whiten clothes, per each litter of water.
Even thought I have to recognize that killing bacteria through UV radiation makes sense, I used all the time to kill odors in the cloth wile I'm in the wilderness.
Hope this helps
