Does Ozone Damage Plastic or Rubber? | National Ozone .

The rumor that ozone can damage rubber or plastic in a home is a very dated topic. So, let's clear this up. To make the point properly, let's go back to what ozone is and how it works. Ozone is oxygen. It has been enriched from the standard O2 molecule to an O3 molecule. We are told that ozone is "Reactive", which means it will react with other compounds or elements.
