When the chemical nature of a substance is changed, its odor is also changed. When introducing ozone with a substance it will react and change the odor of that parent substance. It will keep breaking down these substances to the point of its original compound or elements. In more simple terms, the O3 molecule quickly absorbs the odor molecule, neutralizing it. Statements have been made that activated oxygen merely masks the odor but does not destroy them.
Misconceptions regarding it arise when applied into a dwelling or structure in the wrong way.
It takes one O3 molecule to destroy one odor molecule. After time, the same condition can return if not used in the right way. Concentration levels, exposure time, or temporary uses are determining factors for curing the problem. Time is needed to destroy all odor-causing molecules. Length of time is determined by the degree of odor.
