A Backpacker Magazine 2016 Editors' Choice winner, the MSR Guardian Purifier physically removes viruses, bacteria, protozoa and dirt quickly and easily on backpacking trips and international travel.

  • Features

    • Winner of both Backpacker Magazine's 2016 Editors' Choice Award and Outside Magazine's 2016 Gear of the Show Award
    • Unlike conventional hollow-fiber technology, the advanced medical-grade fibers in the Guardian block viruses—something most other hollow-fiber filters cannot do
    • Physically removes viruses, bacteria, protozoa and particulate, including hepatitis A, E. coli, giardia, cryptosporidium and more
    • Purifies 2.5 liters per min.
    • With every stroke, the purifier uses 10% of its water to flush the contaminants in its filter back into the source; this means you'll never have to hassle with back-flushing
    • Rugged construction is designed to withstand freezing and drops up to 6 ft.

    Made in USA.
