MSR MiniWorks EX Water Filter


Delivery options:

Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


The MSR® Miniworks™ EX water filter is lightweight, with the same easy pumping action and carbon-cored ceramic element as the MSR WaterWorks™ EX filter, but without the final membrane 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 Dromedary™ 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.
