Cost-effective efficient and exceptionally easy to use.

MSR's MiniWorks™ Filter is one of the most cost-effective and user-friendly water filters on the market. This compact and lightweight filter features an opposing-action lever that is easier to use than bike-pump-style water filters. An Activated Block Carbon Filter inside the pump removes many chemicals including pesticides iodine and chlorine from the water. It even removes most odors and improves the taste of the water you're pumping. The US Marines adopted the MiniWorks microfilter for global use by the Amphibious Raids and Reconnaissance Division.
