A:Answer I did not Ask you if it gives off any "harmful," ozone, but rather "any" ozone at all. You try to evade the real answer which is: yes, this machine does produce ozone as stated by a number of asmatics and review websites that tested the device. It is not certified as "ozone" free like some of these (very few) are. There is also no proof that if you turned off the plasma wave, if that would stop the ozone.
