MSR HyperFlow Water Filter

• 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.
