Ultra-fast, lightweight, and efficient water treatment
The HyperFlow utilizes the latest Hollow Fiber Technology in a package 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. You'll feel extra safe knowing that MSR tests all HyperFlow Microfilters prior to shipping. Included is a Quick Connect Bottle Adapter™ — allowing direct connection to all MSR hydration products and a variety of other wide-mouth containers — and an advanced pre-filter to prolong the life of your filter.
The Hyperflow cartridge filters up to 1000 liters, and replacements are available separately. Results will vary depending on water conditions; silty water will clog your filter membrane faster than clear water. Remember to backflush your Hyperflow frequently, and use a pre-filter for maximum cartridge life. International Restrictions Apply
