I think it's pretty well established that ozone can interact unpredictabily, especially with chemically complex modern building materials. Here is one anecdotal example: https://www.reddit.com/r/homeowners/comments/d2rjsb/ozone_generator_left_a_bad_odor/ https://www.reddit.com/r/homeowners/comments/d2rjsb/ozone_ge... N95 masks actually seem like one of the few use cases that make sense, as their composition is well known and they can be easily enclosed. Even when ozone generators work as expected, they can take months to remove odors from spaces.
