The MSR Guardian Purifier is the most advanced back-country filter. Most water filters out there are exactly that, water filters. The MSR guardian is a filer and purifier. That means it has the ability to filter out viruses too. This is the ultimate filter for 3rd world travel or the most rugged back-country terrain. This technology was developed by our US military squads and now this advanced technology is available to travelers around the world.
Its advanced hollow fiber filter offers the most reliable way to purify even filthy water conditions. Add its long-lasting performance and revolutionary self-cleaning ease, and this may be the only treatment device you’ll ever need.
Ever since the introduction of this purifier, the MSR Guardian Purifier has been racking up awards for their advanced holo-fill technology.
