The MSR® WaterWorks™ EX Water Filter has a rugged, lightweight polyurethane housing. The carbon-cored ceramic filter element removes protozoa, larger bacteria, and some chemicals (including iodine and chlorine), as well as odours and tastes. A 0.2 micron final membrane filter removes any remaining bacteria, and acts as a second line of defence around the ceramic filter.

The side-mounted lever is easier to use than bike-pump-type filters. The base of the filter is threaded to screw directly onto Nalgene® wide-mouth water bottles or all MSR Dromadary™ Bags, reducing spillage and the risk of cross-contamination with unfiltered water. The over-pressure relief valve vents water back down the intake hose, so you don’t get soaked with untreated water. A gauge is supplied so you can determine when it’s time to replace the ceramic filter element.

Filters at 1L per minute flow rate using the AirSpring™ air bubble technology.

Effective against all protozoa, and most bacteria, including smaller ones such as Campylobactor, some chemicals (including iodine and chlorine), and odours and tastes.

Foam pre-filter included.
