Ozone Generator in a car...

[summers]

I used one of these recently to get the dog smell out of a car I bought. Was super effective for that. I actually had to get in the car about halfway through to turn on the ac. I can see this as a possible alternative to CO. Not quite sure on the efficacy, but at least if it worked, the car won't smell like smoke or a decomposing body haha.

Looked into ozone exposure and it seems more dangerous than deadly.
