Best Water Filters for Trail Running of 2024

Check out iRunFar’s picks for the best water purification devices for trail runners and ultrarunners.

Numerous water purification methods can suit various needs and hydration preferences, but choosing the best water filter for trail running requires a few special considerations. Filters that have built-in flasks allow for easy water filtration on the go. Some filters work better for bladders, and some are ideal for small soft flasks or hard-sided water bottles. Some options are best for individual use, while others are ideal for a small group refilling together.

Certain methods work best for clear-flowing mountain streams that we runners constantly seek, while other systems, or combinations of them, can purify the most unappealing water sources. Regardless of the type of water you’re filtering, you want to have confidence that it’s going to be safe to drink. We judged water filters on their flow rates, ease of use, and ability to be carried in a running pack. We also considered the types of contaminants that they could remove from the water.

When traveling in areas where we’re concerned about viruses in the water, we trust the SteriPen Ultralight UV Water Purifier to keep us safe and healthy. We also keep some Aquatabs 8.5mg Tablets X30 in all of our running packs for emergencies.

To help you choose the best system for your needs, we researched the world of water purification and tested the best options for trail running.
