The best way to clean the air Ozium®, the original air sanitizer, is a mechanical and chemical system that actually eliminates smoke and unpleasant odors and reduces airborne bacteria. Ozium has been proven effective by bacteriological laboratory testing and over 40 years of use. It’s not a masking agent; it’s a hardworking air sanitizer that leaves rooms smelling fresh and clean. Ozium actually cleanses the air through glycolized action. Lighter-than-air particles are dispersed in the air and remain there for up to three or four hours — effectively sanitizing the air.
