Its true that most pollutants will be "evaporated" by a good ozone generator within its specified operating space. But there isn't a single brand that will guarantee that they can "kill" every air particle.
Ozone generators are no joke. Please operate them safely as they can seriously damage the human body.
Ozone reacts to air pollutants and chemicals differently. This in many households CAN result in a variety of harmful by-products. For example, when ozone was mixed with chemicals from new carpet in a laboratory setting, the ozone reduced many of the chemicals but created a variety of dangerous organic chemicals in the air. While the target chemicals were reduced, the dangerous byproducts were still left to be ingested.
Ozone generators under proper circumstances have great benefits. I advise you learn more about ozone generators and your particular grow environment.
