The MSR Guardian Gravity Purifier is a great choice for providing you with safe water around the world, removing viruses, bacteria, protozoa, sediment and microplastics hands-free. Simply hang it while you go about your tasks at the hostel, basecamp or campsite. Engineered for travel this rugged, military-grade construction, compact system fits easily in carry-on luggage and smaller packs.

The generous 10L reservoir supports the daily water needs of multiple people and makes it easy to fill. Due to its simple design this purifier is ideal to maintain in the field. No backflushing required, by simply opening the purge hose it flushes the system to clean it and maintain flow rate.

Originally designed to protect servicemembers in the field, this rugged purifier handles the abuse of travel and meets the NSF P248 military testing standard. The NSF P248 Testing Standard is the most rigorous scientific certification for proving a treatment device safely removes claimed contaminants from challenging wilderness water sources. Guardian devices are the market’s only purifiers to pass the military standard P248 testing for virus removal.

The Guardian Gravity Purifier provides better-tasting water thanks to the two-stage purifier which includes activated carbon to reduce chemicals and unpleasant tastes and odours. It also benefits from a fast flow rate, up to 1 litre in 2 minutes with optimal reservoir hang height of 6 feet, 2.5x faster than the next leading gravity purifier.
