So I am told, Ozone, is very bad for the Lungs, causing tissue breakdown in the alveoli. [Linked Image]
Are the Ozone generators, that were being sold back then, the same sort of thing as a Negative Ion generator, sold in large amounts during the 1980's-90's?.
My uncle had one, I don't think that it worked properly, I never felt any "refreshing effects" from it. [Linked Image]
