Water Without the Filter Taste

The MiniWorks EX Microfilter is MSR’s best-selling water filter for a reason. With carbon in its core, the MiniWorks EX filters out unpleasant tastes and odors as well as bacteria, particulates, protozoa, and more. If you’re going to trek through the alpine, you deserve mountain water that actually tastes fresh. Crip, clean water is filtered efficiently through MSR’s AirSpring Accumulator, which guarantees a liter filtered every minute. The filter should last for 2000 liters, and an indicator lets you know when it’s time to replace the filter.
