MSR 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%.
