Best Backpacking Water Filters And Purifiers Of 2023

Check out the best backpacking water filters and learn what factors to consider when choosing one for your next adventure.

A backpacking water filter is a key essential for any multi-day outdoor adventure. Parasites and bacteria live in the lakes and rivers that you rely on to stay hydrated in the backcountry. Giardia is the most common and can cause abdominal cramping, nausea, diarrhea,  and vomiting – not exactly what you had planned for your next adventure, right?  

Some argue that you don’t always need to filter water where streams are fed by fresh snow-melt, but keep in mind that if livestock, wildlife, or humans can reach an area, so can contaminants that are transferred via fecal matter.

It’s also important to understand the difference between a water filter and a water purifier so you can be sure that the water you’re drinking is clean, safe, and won’t cause illness out in the backcountry.

Here are the best backpacking water filters and water purifiers as well as tips for how to choose the right purification system for your adventures, written by by Kristen Bor

An outdoor travel blog on a mission to inspire and empower you to get outside with a strong skill set

Hi! I’m Kristen. Thanks for stopping by! If you love to travel and spend time outside, you’ve come to the right place. I am here to inspire you to get out there and to help you plan your next adventure.

I started Bearfoot Theory because I wanted to dispel the myths that prevent many people from getting outside. As a late outdoor bloomer myself, I’ve found it easy to be intimidated by adventure websites and magazines that feature people skiing off cliffs and kayaking class 5 rapids. You might think, “if that’s what being outdoorsy is, then that’s not me!”

But I’m here to tell you that you don’t have to be a risk-taking, adrenaline junkie to have an awesome outdoor vacation. You also don’t need the most expensive gear, to plan for weeks on end, or do things that are beyond your comfort level.

My mission with Bearfoot Theory is to be a source of inspiration and information for everyday people looking to have an authentic outdoor experience. I’ll show you that an outdoor lifestyle is easy, inexpensive, accessible, and fun. I’ll share with you my favorite outdoor off-the-beaten-path destinations in the West (and occasionally elsewhere), tell you what gear you do and don’t need, and help you build more confidence in your outdoor abilities.
