The 8 Best Camping Water Filters & Water Purifiers of 2021

Clean drinking water is the most important resource when camping, heading into the backcountry, or traveling abroad. One bout with a stomach bug is all it takes to reinforce this rule. Thankfully the simple step of taking a water filter camping allows you to have a constant supply of clean and high quality water to drink. While different products have different approaches to the same end goal of clean water, all of the best camping water filters place an emphasis on being lightweight, easy to use, and highly durable.

An important consideration is what you may be trying to avoid in your water. Water filters strain out protozoan cysts and bacteria which you’ll often come across in the US and Canada. Water purifiers strain these as well as viruses which are smaller, and you may want to go this route if you’re traveling to less-developed areas of the world. No matter what the location of your next off-the-grid adventure is, here are some of the best camping water filters and purifiers of 2021:
