Why We Like The MiniWorks/WaterWorks Ceramic Filter Element

When we can fit the element gauge around the filter of our MSR WaterWorks EX or MiniWorks EX, it's time to replace the filter with the MSR Marathon EX Ceramic Element. This ceramic element removes protozoa and bacteria down to 0.3 microns, including giardia and cryptosporidium. For those with an older MiniWorks or WaterWorks, not to worry—this MSR element not only works with them, but it also increases flow rate by 25%.


  • Replacement filter extends the life of your MSR microfilter
  • Filter meets standards for eliminating bacteria and protozoa
  • Compatible with MRS MiniWorks EX or WaterWorks EX filters, as well as older MiniWorks and WaterWorks models
