The MSR AutoFlow XL Gravity Filter offers pump-free filtration for basecamp, scout troops, horsepackers and other backcountry groups. One 10-liter fill supplies 2 people with a day's worth of water.


  • This extra-large AutoFlow gravity filter system delivers 10 liters of clean water fast—all while you set up camp, prep dinner or relax
  • Its big capacity means fewer trips to the river to haul the water you need
  • Similar in packable size to a 4L system, the AutoFlow XL filter's durable flat base doubles the water volume and still weighs just 12 oz.
  • Operation is simple: fill the 10-liter collection reservoir with dirty water, connect it to the filter with the quick-disconnect fitting and let the water flow
  • Efficient hollow fiber technology filters up to 1.75 liters per minute
  • 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"
  • Constructed with a rugged 3D film reservoir with RF-welded seams and a 1,000-denier flat base that resists wear and tear
  • Field-maintainable design has a sediment trap in bottom of bag; filter is easily cleaned on the fly—no tools required
  • Separate hang strap and bag clip allow for easy hanging and maximum convenience
