Check out this great article about Ozone and Ozonators by Kaisa Williams, Swimuniversity.com:

Ozone is a strong natural oxidizer which breaks down chemicals and bodily fluids, including:

soap

deodorant

hair spray

cologne

makeup

perfume

body lotion

hand cream

sun tan lotion

saliva and urine

When used in conjunction with your regular sanitizer, ozone helps kill pathogenic bacteria, germs, and viruses, as well as oxidizing organic contaminants. This leads to dramatically better water quality than you would have with just chlorine or bromine alone.
