MSR Guardian Water Purifier for Outdoor, Worldwide Travel, and Emergencies

Originally designed for the U.S. Military, the MSR Guardian Water Purifier Pump utilizes advanced water filtration technology to ensure the safety and health of troops in remote locations around the world. After six years of research and development, this pump purifier was engineered to remove viruses (such as norovirus, rotavirus, hepatitis A), bacteria (such as E. coli, Shigella, salmonella, cholera), protozoa (such as giardia, cryptosporidium, amoebae), and sediment from contaminated water sources anywhere on earth. It meets the stringent NSF protocol P248 testing standard for the U.S. Military, using medical-grade fibers to provide protection from even the smallest microbiological waterborne threats.

Built for speed, simplicity, and safety, the pump can deliver a rapid 2.5 liters per minute and has a long-lasting advanced filter that can treat up to 10,000 liters of water. It can withstand freezing temperatures, drops, heavy use, and harsh environments. A self-cleaning mechanism ensures reliability, flushing contaminants in the filter back into the source, meaning there is no backflushing or scrubbing of cartridges necessary to maintain flow.

Ideal for wilderness, backcountry use, expeditions, global travel, and emergency preparedness, the MSR Guardian Water Purifier Pump measures 8.2 x 4.7 inches and weighs 17.3 ounces. It is proudly made in the USA and is perfect for military-grade water purification, as it removes viruses, bacteria, protozoa, and particulate from contaminated water sources virtually anywhere on earth. With its ability to handle freezing temperatures, drops, heavy use, and harsh environments, this pump is truly built to last. Additionally, the pump self-cleans on every stroke, providing consistently fast flow rates with zero hassle—no backflushing or filter-scrubbing ever required. This makes it ideal for backcountry, expeditions, global travel, and survival.
