Trusted performance for backcountry, travel, and preparedness

The MSR Guardian Water Purifier Pump was developed with a mission: to deliver clean water when and where you need it. Originally designed for U.S. Military use, this purifier combines field-proven filtration with a design crafted for rugged reliability. Six years of research and development shaped a pumping system that guards against a wide range of contaminants, from microscopic threats to particulate matter, so you can focus on your route and your next camp.

What makes Guardian different

  • Removes viruses (norovirus, rotavirus, hepatitis A), bacteria (E. coli, Shigella, Salmonella, cholera), protozoa (Giardia, Cryptosporidium, amoebae), and sediment from water sources worldwide.
  • Meets NSF protocol P248 standards and uses medical-grade fibers to provide protection from the tiniest waterborne threats.
  • Pumps at a rapid 2.5 liters per minute and treats up to 10,000 liters of water, with rugged performance in freezing temperatures and tough environments.
  • Self-cleaning on every stroke—no backflushing or filter scrubbing required to maintain flow and reliability.
  • Compact, durable design: 8.2 x 4.7 inches and 17.3 ounces; proudly made in the USA.

Real-world value you can feel

In the field, clear water is a quiet comfort. The Guardian’s fast flow helps you keep moving between water sources, while its robust construction withstands drops, freezing, and heavy use. The self-cleaning action reduces routine maintenance and simplifies long trips, so you can concentrate on route planning, safety checks, and the next camp.

Whether you’re crossing alpine ridgelines, trekking through arid canyons, or preparing an emergency kit for unpredictable weather, the Guardian combines filtration that targets a wide range of contaminants with practical, field-ready engineering. The result is a purifier that is not just capable, but dependable when it matters most.

Two quick-reference lists

  • Key capabilities: purifies viruses, bacteria, protozoa, and sediment; rapid 2.5 L/min flow; treats up to 10,000 L; self-cleaning; freeze-tolerant.
  • Ideal scenarios: backcountry treks, expeditions, international travel, and emergency preparedness kits.
