Compact Backcountry Water Filter

The MSR MiniWorks EX Microfilter Water Filter is a versatile and reliable water filtration solution designed for a wide range of outdoor activities, including camping, hiking, backcountry adventures, global travel, survival situations, and emergencies. Engineered for frequent and heavy use, this microfilter pump delivers long-lasting, field-maintainable water filtration, ensuring clean, reliable, and taste-free water in demanding environments.

At the heart of the MiniWorks EX is the Marathon EX carbon/ceramic element, which removes bacteria (such as E. coli, Shigella, salmonella, and cholera), protozoa (such as giardia, cryptosporidium, and amoebae), and particulate matter. Additionally, the carbon core helps eliminate unpleasant tastes and odors caused by organic compounds like iodine, chlorine, and pesticides.

One of the standout features of the MiniWorks EX is its innovative AirSpring Accumulator, which allows it to pump water at a rate of one liter per minute. This impressive flow rate can be easily maintained in the field without the need for any tools, making it a practical and efficient choice for outdoor enthusiasts.

The MSR MiniWorks EX Microfilter meets the rigorous NSF protocol P231, ensuring the removal of 99.9999% of bacteria and 99.9% of protozoa throughout the filter's replaceable life, which can treat up to 2,000 liters of water.

Versatility is another key strength of the MiniWorks EX. It is compatible with a wide variety of water containers, including Nalgene, Camelback, and MSR Dromedary Bags (sold separately), allowing users to choose the water storage option that best suits their needs. The microfilter can be screwed onto the threaded lids of these containers, or water can be pumped directly into a hydration reservoir drinking tube.

Weighing just one pound and measuring 7.5 x 2.75 inches, the MiniWorks EX is both lightweight and compact, making it an ideal choice for backpacking, hiking, and other outdoor activities where weight and space are at a premium. A storage bag is included, and the pump is backed by the manufacturer's limited lifetime warranty, ensuring its long-term reliability.

Thousands of adventurers worldwide have put the MSR MiniWorks EX Microfilter to the test and have found it to be a dependable and indispensable companion in demanding outdoor environments. Whether you're embarking on a backpacking trip, facing a survival situation, or preparing for an emergency, this microfilter water pump offers the peace of mind that comes with reliable, clean, and great-tasting water.
