That was my thinking. I basically built something like that. I bough small ozone generator that has a pump, inlet and outlet (it was designed for bubbling ozone through water). I put both inlet and outlet inside large cardboard box and when I run it I put the whole box outside because the box is not sealed and small leaks or venting it at the end would release ozone into my apartment which as you say is lung and throat irritant. I haven't notice any damage to plastic. It may have some effect on glue on the duct tape I used to modify the box.

I'm running the generator for 10-15 minutes and then let the stuff sit in generated ozone for additional 20 minutes. But I have no idea if I'm improving my security or just performing security theater for my own amusement.
