SEATTLE, WA — In 2009, the U.S. military selected MSR® (Mountain Safety Research®), the Seattle-based manufacturer of high-performance outdoor equipment and the leader in backcountry water treatment technology, to create a device capable of keeping its service members safe from waterborne illnesses virtually anywhere on earth. After six years of research and development with MSR’s in-house water laboratory and in collaboration with the U.S. military (Army and Marine Corps), MSR created the solution: the Guardian Purifier.

Built for international travelers, outdoor recreationalists, and emergency preparedness, the military-grade microbiological purifier is the world’s most advanced portable purifier that physically removes all pathogens and particulates with single-step purification for all water types (clear, turbid and filthy). It’s capable of transforming even the most challenging water sources into clean, microbiologically safe, drinkable water.

The Guardian™, which received an OutDoor Industry Gold Award in the accessories category at the OutDoor European trade show in Friedrichshafen, was one of 9 winners selected by an international jury of outdoor experts from a pool of 329 entries from 35 different countries. “This is the first pump purifier that mechanically eliminates viruses from water,” said the judges when describing the MSR Guardian Purifier. “Other outstanding features include its user-friendly handling, long life span and compatibility with standard drinking bottles. In addition, the purifier cleans itself while pumping. This is why this product deserves a Gold Award.” The jury also recognized the Guardian for its degree of innovation, functionality, design and workmanship.

Unlike conventional purifiers, the Guardian uses custom-engineered, medical-grade hollow fiber technology to block the tiniest waterborne microbial pathogens. The pump physically removes viruses, protozoa, bacteria, and particulates at a rapid 2.5 liters per minute—with no chemicals, UV light, pre-filtering, or waiting—for up to 10,000+ liters.

With the Guardian, users no longer have to be intimidated by field maintenance, product vulnerabilities in various water types, and user error. Thanks to its patent-pending design, the purifier self-cleans, never requiring users to back flush or to scrub filters in the field to maintain flow.

Originally built for U.S. military squads, the Guardian meets NSF Protocol P248, the standard used to test U.S. military purifiers for removing viruses, bacteria and protozoa in water abundant with silt and particulates. Its rugged design withstands heat up to 160°F, freezing temperatures, drop testing (up to 6 feet to concrete as conducted by MSR’s water research lab), and up to 300 pounds of crush force.

MSR’s new Guardian Purifier will debut at Outdoor Retailer Summer Market in August 2015 and will be available online and in stores starting January 2016.
