MSR MiniWorks EX Microfilter

The MiniWorks EX is designed for tool-free maintenance. You can simply unscrew the housing, remove the ceramic element, and scrub the exterior with the included scouring pad to restore the flow rate.

No, this filter is designed to remove bacteria, protozoa, and sediment. It does not remove viruses, so if you are traveling in areas where viruses are a concern, you should pair this filter with a chemical treatment or purifier.

The filter element is rated for a 2,000-liter lifespan. Depending on the clarity of the water you are filtering, you may need to replace it sooner if the ceramic element becomes too worn down from repeated cleanings.

Yes, the integrated carbon core is specifically included to reduce unpleasant tastes and odors, including chemicals like chlorine and pesticides, making water from questionable sources much more palatable.

Yes, the base of the filter is designed to thread directly onto standard wide-mouth water bottles, such as Nalgene, allowing you to pump filtered water directly into your container without needing an extra hose.

The unit weighs 1 pound. While it is incredibly durable and reliable for long-distance trips, it is heavier than some hollow-fiber squeeze filters, so it is best suited for hikers who prioritize field-serviceability and longevity over absolute minimum weight.
