SectionHiker is Philip Werner's independent hiking site, and this gear guide is its standing answer to a practical problem: how to make backcountry water sources safe to drink. Werner dated the current version April 5, 2026, and the page is flagged as a nine minute read.

Rather than stopping at a ranked list, the guide works through the treatment methods themselves — squeeze and hollow-fiber filters, chemical treatment, and ultraviolet purification — with practical usage guidance attached to each. That structure is what earns it catalog space. Whether you want a filter or a purifier depends on where you are hiking and what you are trying to remove, and this page covers both categories instead of assuming one answer suits every trip.

Werner keeps a separate FAQ explainer devoted to the ultraviolet method, published March 2, 2022 and tagged under the site's Frequently Asked Questions section, if you want that one approach in more depth before deciding whether a UV pen belongs in your kit.

Two honest limits. It is a ranked roundup fixed to early 2026, so the specific models it names will age faster than the method comparison around them; read it for the categories rather than as a current shopping list. The page also carries affiliate links, which SectionHiker discloses in a line above the article.
