It goes without saying that exposure to hgh level of ozone can cause degrees of damage to lung tissue, all the way to of course, expiring.
One way to tell if an ozone machine is putting out too much for an enclosed spaced is when it begins to edge up and start a slight bitter taste, and subtle beginnings of stinging in the lungs. When the first hints of these happen, I back units way off, and know the limits through feeling my way through this.
Question is... do these hot corona units which put out ozone and NOx, does the NOx also begin to cause damage to say, lung tissue. Specifically, in these hot corona units, should one be more concerned with ozone or NOx, or both equally?
