A true game changer that makes almost any questionable water source safe to drink. This purifier means you don't need to carry chemical water treatment, or a UV purifier when you are in virus territory. It removes viruses, bacteria, and protozoa. And it back-flushes itself during normal operation, so it's a lightweight and convenient package for travel and expeditions.

  • Filters 2.5L per minute at 60-80 strokes per minute
  • Hollow fiber filter removing bacteria and protozoa
  • On every stroke, 10% of the water flushes contaminants from the filter back into the source, so no back-flushing or scrubbing cartridges
  • Withstands freezing
  • Drop tested from 6 feet to concrete, as conducted by the MSR lab
  • Includes storage bag and manual
  • Note: the quality of water will significantly affect the filter's life
