About MSR MIOX Water Purifier

The MIOX Purifier represents a revolution in water treatment It's ultralight, compact, and easy to use with no pumping, maintenance, or iodine required

Developed in conjunction with the U S military, the MIOX Purifier offers unrivaled ease of use and reliability for purifying large volumes of water, making it ideal for outdoor recreation, travel, and disaster-preparedness It works by creating a powerful dose of mixed oxidants (MIOX), which is then added to untreated water, inactivating all viruses, bacteria, Giardia, and Cryptosporidium (which even iodine doesn't kill) And since the MIOX Purifier needs only common camera batteries and salt to operate, it's maintenance-free, delivering more water, more easily than any purifier ever before

This product can only be shipped to U.S. addresses.
