SteriPEN Prefilter On YouTube.
This video answers two questions. As you go to fill a bottle when the water is very deep, and how do you deal with a cloth filter, water anywhere? This solution uses a bottle of SmartWater water, but I think every plastic bottle of soda or fruit juice should work. Check my writeup more goodenoughstuff.blogspot.com And by the way, yes, there is a fountain in the background, but it is natural spring water, and we are really in the mountains.
