I was not suggesting using one in an Ozone generator in a coach for an extended period. Personally it should be left to professionals to remove the smells. Ozone can kill if you are exposed to it too much and too long. Pros use a sealed chamber for up to 72 hours max, as I remember. It will degrade a lot of things from finish to fabric if used too long. The chamber we used cost over #1,000 to build, and was a little scarey to run, it does smell like fresh lightening, and cannot be filtered with a respirator. Caution first, but very effective.
The only thing it did not clear was mouse pee, and we used other products for that.
