MSR HyperFlow Microfilter

Why did MSRs Hyperflow Microfilter win the 08 Backpacker Editors Choice Award Its super small (7 x 3.5in), super light (7.4oz), and it pumps three liters per minute. That means you can pack quick-filtering power without sacrificing weight or space on your fast-pace backpacking trips. The Hyperflow Microfilters float end stays face-down in the lake or stream and wont clog up as you pump, and an included Quick Connect Bottle Adapter connects to MSR, Nalgene, and other bottles with 63mm threaded openings. No tools are needed to disassemble the Hyperflow Microfileter for on-the-go cleaning.
