Are ozone air purifiers harmful?

I have allergies, as does my 7 y.o. daughter. I seem to always have a sinus or ear infection. I bought the 0 machine thinking it would help with the air quality in our home, but now I’m thinking it might have been a huge waste of money. When I first bought the system, I could smells the ozone strong in the house… now I can’t smell it at all. The machine has been looked at and its fine. I am still getting infections and sometimes I think that the ozone may be harmful to us.
Does anybody know anything about ozone air purifiers??

Thanks!
