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.

  • Reliable: Durable carbon/ceramic element ensures safe, taste-free water - even with frequent, heavy use.
  • Field-maintainable: Can be cleaned repeatedly for full filter recovery with no tools required.
