MiniWorks EX

Reliable & Field-Maintainable Water Filtration for Backcountry Travel.

The MSR MiniWorks EX Microfilter is a durable, easy-to-maintain water filter designed for backpacking, hiking, and international travel. Using a ceramic and carbon filter, it effectively removes bacteria, protozoa, and particulates while improving taste and odor.

Built for long-term reliability, the filter is field-cleanable without tools, ensuring consistent performance in remote locations. The AirSpring Accumulator™ pump delivers fast, efficient filtration, producing up to 1 liter per minute. It’s compatible with MSR Dromedary bags and standard wide-mouth bottles, including Nalgene bottles, for seamless integration into any hydration setup.
