Description
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.

- Microorganisms in backcountry water can pose an immediate risk to your health.
- NSF P231 and P248 are the most rigorous scientific standards for proving a device safely removes these microbes from challenging wilderness sources.
- These standards confirm the device’s effectiveness throughout the entire life of its filter.
- All MSR filters pass P231 for removal of bacteria and protozoa, and our Guardian Purifiers are the market’s only to pass the military standard P248 testing for virus removal.
