MSR Guardian Gravity Water Purifer for Backcountry Use, Global Travel, and Emergency Preparedness

The MSR Guardian Gravity Water Purifier has you covered with safe water around the world—from local backcountry to remote villages and home emergencies. It’s advanced, two-stage filtration utilizes activated carbon and hollow-fiber technology to purify water from most any source, meeting NSF protocol P248 military testing standard for removing viruses (99.99%), bacteria (99.9999%), protozoa (99.9%), sediment and microplastics from “worst-case” water conditions, while reducing chemicals and unwanted taste and odors from your water. Simply hang the 10-liter reservoir and purify up to 1L in 2 minutes based on an optimal hang height of 6 ft above the clean water output, providing safe water for your group. It also includes a universal bottle adapter for easy connection to most common bottle shapes and sizes. The whole system measures 12.5 x 4 inches and weighs 18.7 ounces. It packs neatly into an included, zippered carry case. Made in the USA. Manufacturer’s 3-year limited warranty.
