Best Ways to Purify Water Without Fancy Gear?
Looking for reliable methods to purify water in the field when you don't have filters, tablets, or fancy equipment. Boiling is obvious, but what about if you can't make a fire? I've read about solar stills and using basic cloth to strain, but never tried them myself. Has anyone found a method that's genuinely effective in a pinch? Really interested in tried-and-true techniques, not just theory.
