MSR MiniWorks® EX

Get the added viral protection that’s critical in popular wilderness areas and developing countries with this comprehensive purifier and microfilter system. The MiniWorks® Microfilter—our best-selling filter for demanding conditions—utilizes a ceramic/carbon element to filter out waterborne bacteria and protozoa, as well as particulate, taste and odors at 1 liter per minute. When viruses are a concern, the chlorine-based Aquatabs® purification tablets add viral defense. Together they provide the most reliable water possible in a compact, lightweight system that’s great for backpacking and international travel.

This system meets U.S. EPA requirements for microbiological water purifiers.

Testing: Meets NSF protocol P231 for removal of bacteria (99.9999%) and protozoa (99.9%) from beginning to end of filter life in “worst-case” water.

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.
