The MiniWorks EX microfilter delivers long-lasting, field-maintainable water filtration in demanding environments. Engineered for frequent and heavy use, it utilises MSR's workhorse Marathon EX carbon/ceramic element to ensure clean, reliable and taste-free water. Thanks to its innovative AirSpring Accumulator, it's capable of pumping one litre per minute and the flow rate can be renewed easily and repeatedly in the field - no tools required. It's lightweight and compact and, most importantly, has been proven reliable by thousands of adventurers just like you.
