MSR AutoFlow Gravity Filter

$109.95

COMBINES WATER FILTRATION, STORAGE AND COLLECTION INTO A SINGLE, LIGHTWEIGHT SYSTEM.

Now with an even lighter filter cartridge, the AutoFlow Gravity Microfilter represents the latest evolution of backcountry hydration, combining filtration, storage and collection into a single, pump-free system. Featuring the latest Hollow Fiber technology and the power of gravity, the AutoFlow microfilter is fast as well—up to 1.75 liters per minute without a single pump stoke. 4-liter reservoirs allow you to filter large quantities at once making it perfect for groups, while quick and easy tool-free cleanings maintain high flow rates on extended expeditions.

  • Testing: Meets NSF protocol P231 for removal of bacteria (99.9999%) and protozoa (99.9%) from beginning to end of filter life in “worst-case” water.
  • No Pumping: Lets gravity do the work so you don't have to.
  • Fast: Filters more than 1.75 liters per minute.
  • Lightweight: Weighs only 10.5 oz. (299 g).
  • Field-Maintainable: Can be cleaned repeatedly without disassembly for flow recovery.
  • Adaptable: Filter directly into most any bottle or reservoir with included Universal Bottle Adapter.
