In the case of the tube type ozone generator it had no means other
convection to move the ozone about.
In the case of the brush discharge the points produced a light but easily
felt (on the face) flow of air.
I drilled large ventilation holes in both after they first failed.

Perhaps your right your relatively strong flow of air may have prevented a
high concentration locally.
I noticed that when the air conditioner was not on, the smell of ozone was
much stronger in the immediate vicinity of the generator and barely
detectable 30 ft away.
Presumable the ozone was decomposed before it had defused 30ft.
