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 unrivaed ease of use and reliability for purifying large olumes 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.
