Use these generators with caution. Keep yourself, other people and pets out of the vehicle or room when using the generator. Also let the vehicle air out after you’re finished using it. These can get dangerous, so follow the manufacturer’s safety recommendations. The EPA has specifically warned that ozone is harmful and that claims about “controlling indoor air pollution” have been refuted by health professionals “for almost a century.” Moreover, the EPA explains that ozone doesn’t remove odor-causing chemicals at concentrations that are safe:

There is evidence to show that at concentrations that do not exceed public health standards, ozone is not effective at removing many odor-causing chemicals.

Lastly, some manufacturers make absolutely bonkers claims like these will practically clean your car or your home for you and remove 50 years of stink from all surfaces. They aren’t magic. Keep your expectations realistic.

Ozone generators come in a wide variety of price ranges and designs and can be purchased online. Ones with a lot of good reviews cost about $60.
