Small and sweet.

All you really want out of a water filter is to make sure you drink liquids that won't make you sick, but it would be nice if the filter didn't take up much space in your backpack, and when it comes to taste: the sweeter the better. The SweetWater Microfilter sits right in the middle of MSR's filter in terms of weight and durability. Its strong, sturdy design dishes out a liter of sweet-tasting water in a single minute, and yet still weighs less than a single pound.


  • Water filter balances durability with lightness for backpacking
  • Activated carbon core helps eliminate taste and odors
  • Unique lever-action pump processes a liter of water per minute
  • Handle folds flat for easy packing and storage
