Ozone generators will kill molds, bacteria and eliminating odors,the surface mold on any material it contacts.
Ozone is gas, it can remove mold odors, tobacco and pet odors and it is widely used in industrial settings as a sterilant. Ozone can reach the mold, and kill it, permanently.
Since ozone is composed of three oxygen molecules, it can combine itself with things like mold and mold spores. It will change them in such ways that it kills the spores and cells that compose the mold. This is the same way it removes odors and other things: killing the bacteria that causes it. Because of its highly-reactive state, the mold and mold spores will die from the gas messing with its chemical makeup.
The fact remains that ozone is capable of killing molds, bacteria and eliminating odors. It can remove mold odors, tobacco and pet odors and it is widely used in industrial settings as a sterilant.
