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

High Flow Rate: Pumps more than 3 liters per minute or one liter every 20 strokes.
Ultralight: Just 7.4 oz. (209 g).
Ultra-small: Just 7x3.5 in. ( 17.8 x 8.3 cm) makes it easy to take along even when space is at a premium.
Field-Maintainable: Can be cleaned repeatedly for flow recovery without tools.
Super Convenient: Quick Connect bottle adapter lets you filter water directly into a variety of containers, including all MSR hydration products and other wide-mouth containers

Restore flow rates in your HyperFlow Microfilter with fresh, new Hollow Fiber media.

Filters up to 1000 liters. Results will vary depending on conditions.

A complete kit for periodic maintenance of your HyperFlow Microfilter pump.
