Best Water Filters

Clean drinking water is an incredibly important consideration for any trip into the backcountry. If you’ve ever had the pleasure of experiencing a stomach parasite (we have, it’s awful), then you already know how critical clean drinking water is. If you haven’t, good! Let’s keep it that way.

For any extended trip into the wilderness you’ll want a treatment method for cleaning your drinking water. But when you start shopping for a good filter or purifier, you’ll quickly find that there are A LOT of different products out there.

We put together this guide to explain key treatment method differences and to share our personal favorite products. We’ve spent hundreds of hours researching and testing these tools, so we hope you find this information helpful.
