How does ozone (O3) remove contaminants and odors?
The combination of three atoms is very unstable, and the third atom will quickly combine with organic molecules such as bacteria, mold, dust, etc. This combination is called Oxidation or Ozonation, which kills the contaminants through the destruction of their cell walls, reducing them to water and carbon dioxide in most cases. Ozone is a very aggressive oxidizer, with typically non-toxic by-products.
