Water filters
Water filters and purifiers make stream and lake water safer to drink. Most portable filters remove bacteria and protozoa but not viruses; for those you need a purifier, chemical treatment or UV light. Squeeze and straw filters suit one person, while pump and gravity systems can treat larger amounts for a group. Check how the filter is cleaned, and protect hollow-fibre filters from freezing, which can damage them.
