Ozone generators are nice to use since they remove any odors from your home. However, they can also be used in the car. Regardless of where you use it, ozone generators are a good tool to help clean your air. They can be dangerous, though.
Ozone is a highly reactive gas that tries to give off its extra oxygen atom to whatever it can. This means that cells exposed to it can be damaged by it. Living things have cells, so they are affected by the ozone gas. This is true for people, plants, animals, and even microbes like bacteria and viruses.

You should always research about things you want to buy. Ozone can be dangerous, but you can use it in a way that won’t harm you or your pets. Sealing up a room is the most important part, so make sure that no ozone can get out from beneath the door or through a window or vent.
Running it for a few hours will clean the room’s air and anything inside of it, removing any odor that might persist through cleaning. Odors can stain anything, so be sure to use the ozone generator when you run out of options.
