Effective & Cleanable Filter

The MSR MiniWorks EX microfilter & purifier are engineered for frequent and heavy use in demanding environments. Both rely on a ceramic plus carbon filter element that's effective against bacteria, particulates, and protozoa. For additional protection from Viruses, the purifier comes with chlorine-based Aquatabs that effectively eliminate up to 99.99 percent of viruses in the water.  Weighing in at just a pound, both the microfilter and purifier have a convenient hand pump that can put out up to one liter per minute. In addition to being able to disassemble the entire system for maintenance, the filters can also be cleaned repeatedly for full filter recovery with no tools required.

Note: At checkout, choose the Ex Microfilter (base price) or the EX Purifier (+ $10).
