Hey! That was my recommendation! Ha!
Yup! Gives the camper a 'new car smell'.
As far as any harm to your body; if you start to feel a sore throat, it's too much so turn it off.
Here's how ozone works; It's chemical formuala is O3. Oxygen is O2. The extra atom of oxygen is easily stripped away from the more stable O2, turning O3 into O2. It's stripped away because it is short one electron and is looking for a molecule that has an extra electron. When it bonds to that molecule, it's a chemical reaction, changing the original into something else.
The most familiar is Iron, or, chemically written as Fe and called ferris. When Fe picks up the extra Oxygen, it turns into Ferris Oxide. Also known as rust. In this case, your stink picked up the oxygen atom out of the Ozone and chemically changed into something else. It's not masked, it is a new molecule altogether. One that doesn't smell to your human nose any more.
Also, ozone kills many types of plants. If the odor is from a plant, like mold, then ozone will kill it and you no longer have a source for the odor. Ozone generators are used in hot tubs to kill algae and other plants and micro organisms that produce bad odors.
Hope that makes sense.
