Another problem is byproduct odors. The point is, scents can work both ways, and humans are very sensitive and react uniquely to odors. Olfactory persuasion is a gamble at best. Perhaps a better way is a lack of odor, which some people describe as a fresh, clean ambiance resembling the scent of freshly laundered bedsheets. No lawsuits are involved, and no one could have an aversion to it.
Ozone is nature's deodorizer and sterilizer, which can now be reproduced commercially.
This can be the perfect scenario for odor destruction. Ozone is produced by lightning, which is why the air smells so fresh and clean after a thunderstorm. The ozone works to oxidize or destroy all the air pollutants. Ozone also occurs naturally from solar-powered chemical reactions involving emission from trees and plants, more commonly known as byproducts of photosynthesis. Many scientists believe the fresh mountain air and forest haze come from this naturally produced ozone.
