Technical Information
Developed in conjunction with the U.S. military, the MIOX Purifier offers ease of use and reliability for purifying large volumes of water
Works by creating a powerful dose of mixed oxidants (MIOX), which is then added to untreated water, inactivating viruses, bacteria, giardia, and cryptosporidium, which even iodine doesn't kill
Destroys viruses and bacteria in 15 minutes
Features a safety indicator to ensure your treated water is safe to drink
Requires only batteries and salt to operate — it's practically maintenance-free
Pocket-sized adaptation of municipal grade purification system
No pumping needed — just add water, shake, and press a button.
No iodine — no health risk or unpleasant iodine taste.
