MSR AutoFlow Gravity Filter

With the latest Hollow Fibre technology and the power of gravity, the AutoFlow microfilter is fast as well - up to 1.75 litres per minute without a single pump stoke. A 4-litre reservoir allows you to filter large quantities at once, making it perfect for groups, while quick and easy tool-free cleaning maintains high flow rates on extended expeditions.

  • 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 almost any bottle or reservoir with included Universal Bottle Adapter.
