In the short amount of rsearch I did on the topic, I found that the only harm is in the presence of high levels of ozone. Which typically, the machines used for treating automobiles, are not capable of. The question is, is it effective in providing the desired(or promoted) results. I can only recommend you the same as I did, and that is to do some internet research on the subject, or ask your physician.
