Description
Description

The MSR Guardian Gravity Water Purifier delivers reliable, high-volume access to clean water in remote places, on the trail, and during emergencies. Its two-stage design blends hollow-fiber filtration with activated carbon to tackle a wide range of water quality challenges.

What sets it apart is a field-ready approach that supports group use without relying on electricity. The purifier has been tested to remove viruses (99.99%), bacteria (99.9999%), protozoa (99.9%), as well as sediment and microplastics from even the most challenging sources, while helping reduce chemicals and unpleasant tastes and odors.

How it works in practice

  • Two-stage filtration uses hollow-fiber membranes to target viruses, bacteria, protozoa, sediments, and microplastics.
  • Activated carbon reduces chemicals and improves taste and odor for a fresher snowmelt, river, or spring source.

Fast, gravity-fed performance

  • Hang the 10-liter reservoir and purify up to 1 liter in about 2 minutes based on an optimal height of 6 ft above the clean output.

Portability and durability

  • Compact system dimensions: 12.5 x 4 inches and a lightweight 18.7 oz, easy to stash in a pack or kit.
  • PFAS-free DWR coating on the included storage case helps keep gear dry while reducing environmental impact.

What’s included and key specs

  • Two-stage purifier, 10L reservoir, universal bottle adapter, hoses and zippered carry case
  • Lifetime capacity up to 3000 L
  • Made in the USA
  • Size and weight: 12.5 x 4 inches; 18.7 oz
  • 3-year limited warranty

Use cases and benefits

Whether you’re heading into backcountry terrain, visiting remote communities, or building an emergency water kit, the Guardian offers a scalable solution for clean water when sources are uncertain. Expect clearer taste, reduced odor, and the confidence to share water with your group.

Note: Benefits are based on the product’s testing standards and features. Real-world results may vary by source water and setup conditions.
