Water Filtration & Purification
Securing a clean source of hydration is your top priority when exploring the backcountry
Our Water Filtration and Purification collection features advanced, field-tested systems designed to remove dangerous waterborne pathogens like Giardia, Cryptosporidium, and bacteria from natural water sources. Whether you are trail running, thru-hiking, or establishing a remote wilderness basecamp, we stock reliable filtration methods that convert wilderness rivers, lakes, and streams into safe, clean drinking water.
Explore our versatile inventory of lightweight squeeze filters, high-capacity gravity systems for groups, rapid pump filters, and chemical purification treatments for emergency backup. We also carry essential replacement filter cartridges and maintenance kits to ensure your system remains unclogged and fully operational during long expeditions. Featuring top industry brands like Platypus, Katadyn, and MSR, our collection at Monashee Outdoors provides the technical hydration safety tools you need to protect your health and stay properly hydrated on every adventure.
