Product Highlights

The MSR SweetWater microfilter is fast and easy to use. The lever-action pump delivers water on both the up and down strokes, with a flow rate of 1+ liters per minute.

If the granular activated carbon filter becomes clogged, it can be cleaned with a simple brushing, and the filter is good for up to 750 liters of water before replacement. The SweetWater even lets you know when the filter becomes clogged by releasing a stream of water from the pressure release valve.

The SweetWater microfilter is effective against bacteria and protozoa such as Cryptosporidium and Giardia, and also removes tastes and odors.

At only 11 oz. and measuring 7.5 in. x 2 in., the SweetWater microfilter is easy to pack and carry.

Kit includes: microfilter, hose float, filter cleaning brush, color coded hoses, prefilter, carry bag and instructions.

  • Josh S. Burlington NC

  • Robert C. Hendersonville NC

  • Jeffrey B. Silverdale WA

    Likes: Efficient little pump. Blows out a lot of water quickly! Easy to use. I think it has been effective, because as of yet no GI issues!

    Dislikes: No complaints! I will let you know if things change!

  • Gerald N. South St Paul MN

    Likes: I have owned a Sweetwater filter for years and have found them to be a very reliable high output filtration device. My old replacement cartridges appear to still work on the new MSR brand which is a major plus.

    Dislikes: The MSR plastic pump connection to the handle does not appear to be the same thickness of plastic as the old Sweetwater version so time will tell whether it holds up or not. My oldSweetwater filet has been on 20+ Boundary Water trips and several hiking trips, it now rest at the bottom of Agnes lake.
