  • Features

    • Backpacker April '08: ''The HyperFlow is so fast and light it converted several editors who had sworn off filters in favor of chemical treatment.''
    • Hollow fiber technology offers an extremely high flow rate of 2.75 liters per minute
    • At just 7.8 oz., the HyperFlow is the lightest, most compact pump filter created by MSR
    • Filter physically removes particles, protozoa, and bacteria down to 0.2 microns in size, including giardia, salmonella, cryptosporidia and others
    • Pump is fully field maintainable and does not require tools for complete disassembly
    • Included Quick-Connect™ bottle cap interfaces with MSR hydration products, Nalgene bottles and other containers with 63mm threaded openings
    • Quick-Connect™ cap allows the pump to attach directly to the bottle or hydration bladder for the most convenient filling
    • Included prefilter attaches to the end of the intake hose and blocks larger contaminants from entering the microfilter
    • Prefilter floats near the surface of the water to avoid intake of contaminants located at the floor of your water source
    • Over-molded end caps on the pump provide an excellent grip and pumping comfort
    • Adapt the HyperFlow pump into a pump-free gravity filter with the HyperFlow Gravity kit, sold separately

    Made in USA.

    MSR has identified and fixed a flow rate issue affecting some cartridges in MSR HyperFlow microfilters. As of February 11, 2009, all filter cartridges sold by REI perform to flow specifications.
