The MiniWorks EX microfilter is the worldwide best-selling microfilter, delivering long-lasting, field-maintainable water filtration in demanding environments. Engineered for frequent and heavy use, it utilizes 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 liter 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, been proven reliable by thousands of adventurers just like you.
