  • Packs down to fit in carry-on luggage and smaller packs
  • 10 L reservoir covers your daily water needs, from cooking to cleaning to hygiene
  • Bottle adapter fits a wide range of bottles, so you can use your favourite
  • Activated carbon reduces chemicals and odours for better-tasting water
  • Advanced hollow fibres feature pores so small they block viruses, the tiniest threats
  • Purge hose cleans the system for you, flushing out debris to maintain flow

USA NSF Protocols P231 & P248:

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.

 

At Outdoor eStore we think that as the world changes, more people head outdoors with less skills, as travel expands to more remote areas and natural disasters keep impacting the natural environment, the MSR Guardian™ Gravity Purifier will become essential equipment for any outdoors person or traveller.

The Guardian Gravity Purifier has you covered 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—its 10L reservoir supports the daily water needs of multiple people. Originally designed to protect servicemembers in the field, this rugged purifier handles the abuse of travel and meets the NSF P248 military testing standard. Over coming years, this will be as important as your tent in your outdoor kit.

Features:

  • Ultimate Virus Protection: Meets 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.
  • Better-Tasting Water: Two-stage purifier includes activated carbon to reduce chemicals and unpleasant tastes and odours.
  • Easy to Fill: 10 -litre reservoir is easy to fill at sinks and streams alike; covers daily water needs for drinking, cooking and hygiene.
  • Simple Cleaning: No backflushing required—simply opening the purge hose flushes the system to clean it and maintain flow rate.
  • 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.
  • Engineered for Travel: Rugged, military-grade construction. Compact system fits easily in carry-on luggage and smaller packs.
  • NSF P248 Testing Standard: 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
