You shouldn't normally being smelling the ozone being exhausted from your Ozonics. In most use cases we are not trying to treat you, we are trying to treat the odor coming off of you. The odor coming off of you is what is getting to the nose of the animal you are after. If you do smell the ozone use that as an indicator that the wind may have switched and it might be necessary to adjust the setup of your Ozonics to maximize ozone in the downwind direction.
