The MIOX Purifier represents a revolution in H2O treatment. It's ultralight, small, 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 H2O, 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 H2O, inactivating all viruses, bacteria, Giardia, and Cryptosporidium (which even iodine doesn't kill). And since the MIOX Purifier necessitys only common camera batteries and salt to operate, it's maintenance-free, delivering more H2O, more easily than any purifier ever before.
