I have as ozone generator which I got on clearance for like $5 you can try if you'd like. I believe I have a 12v plug for it somewheres.
i'm surprised that even such a thing exists let alone for use in a closed space like a car. ozone is poisonous IIRC. could give you a good head buzz if you hotbox the car

I have some knowledge of ozone from my UL days. Ozone in concentrations sufficient to actually purify air or clean surfaces exceeds government (FDA if I remember correctly) safety limits. The safe exposure limits are very time dependent. The problem is that ozone works by "Oxidizing" stuff . . . including various aspects of our bodies. UL would not List room type ozone generators/air purifiers that were intended for use in occupied rooms. Some of UL's competition (ETL for example) did List these products for some reason. Ozone generators are Listed by UL for use in unoccupied spaces such as empty hotel rooms. Ozone is safely used for purification of drinking water and of pool and spa water. Anyone who uses an ozone air purifier should stay out of the enclosed space while it is in use and then make sure the space gets well ventilated afterwards.
By the way, an ion type air purifier is not necessarily an ozone generator. If it is UL Listed it will have been tested to make sure it doesn't produce more than minimal amounts of ozone.
