> Airing out the room won't remove the sources of odor. This can be stuff like smoke residue, stuff the carpet cleaner couldn't pick up, etc The source needs to be cleaned from surfaces, encapsulated (i.e. by painting over it), or removed by disposing of uncleanable materials like smoke residue on carpets. > Name me something physical that is actually "destroyed" (mind the laws of Physics). The use of the word is used to describe the destructive process that causes a specific thing to not exist, and almost always means it was turned into something else. I don't think we disagree about the physics, only about whether the byproduct of the conversion resulting from oxidation with ozone can be harmful or not. If the citations I've provided haven't convinced you of the risks of using ozone generators for air quality, then by all means enjoy whatever methods work for you.
