HyperFlow™ Microfilter

HyperFlow microfilter


It will change the way you travel in the backcountry.

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 MSR® hydration products and a variety of other "wide mouth" containers—and an advanced prefilter to prolong the life of your filter.
