The HyperFlow microfilter utilizes the latest Hollow Fiber Technology and our most advanced engineering to make water treatment so small and so easy to use, it will change the way you travel in the backcountry. Its ergonomic design, diminutive size and tool-free maintainability make it just as appropriate on day trips as it is on multi-day excursions. Add a filtration rate of 3-liters per minute and you've got the most efficient microfilter ever created. Also included is a Quick Connect bottle adaptor—allowing direct connection to all MSRhydration products and a variety of other "wide mouth" containers—and an advanced prefilter to prolong the life of your filter. 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 Technical Specs Best Use- Backpacking Filter Type- Pump Filter Medium- Hollow fibers Removes/Destroys- Protozoa and Bacteria Pump Force- Unavailable Pump Strokes Per Liter- 20 Output- 3 liters per minute Housing Material- ABS plastic BPA Free- Yes Field Cleanable- Yes Dimensions- 7 x 3.5 inches Weight- 7.8 ounces
