MSR SweetWater SiltStopper Replaceable Prefilter

When your SweetWater MicroFilter stops producing crystal clear water, replace its innards with MSR's SweetWater SiltStopper. This 5 micron filter works particularly well in silty, glacier fed, and tonic waters found all over the world. It also decreases cleanings, protects your pump, and reduces waste after use. Even through MSR designed it for the SweetWater, the SiltStopper is compatible with any MSR filter.
