Disinfects drinking water (at 5ppm), sanitizes food contact surfaces (at 25ppm), a healthcare environmental surface disinfectant (at 500ppm, 7-1g tablets/48 oz). Less reactive, and over 2.6 times more potent than chlorine bleach in the creation of FAC for oxidation, chlorine dioxide is the obvious choice for those looking for the most efficiency means of destroying an almost unlimited range of pathogens from environmental surfaces. Excellent for total room deodorizing and air sanitization. EPA® registered. NSF® . USDA Organic.
