Health concerns ? I think so.
I would encourage readers and repliers to go to the EPA wed site, Type in "ozone" and it will come up.
According to the EPA-
" At ground level , ozone is a harmful pollutant "
" Breathing ozone can trigger a variety of health problems including chest pains, coughing, throat irritation and congestion. Ozone can also reduce lung function, and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue. Ground level ozone also damages vegatation and ecosystem"
No where do I find this warning in their advertising. Sounds like a dangerous product that should have some warnings included especially for anyone who already has these health conditions.
If the owner of ozone is going to sue states to force them to allow the use of his product. Wait till some one gets sick or worse from the use of this pollutant and he gets sued.
