No iodinated product is presently approved by the U.S. EPA for more than six weeks of temporary, emergency use. There are documented records of Peace Corps volunteers who returned from Africa suffering from acute iodine toxicity from having to drink iodinated water over a period of time.
 
Additionally, HaloPure has many advantages over iodine-based systems:
• Imparts no objectionable taste or odor from a surplus of chemical, even in higher-temperature environments
• Results in sweet, fresh-tasting water—doesn’t smell “like dead fish”
• Operates well in cold temperatures
• Poses no risk of overdosing
