Bought the parts a while ago for an ozone generator to remove laser-cutting odours from the garage. It ended up being much too powerful for that so wasn't used and I didn't bother putting it in a case.
A few days ago I was reading how Ozone is a very effective virus killer, and put this unit together to clean packages and groceries from COVID before bringing them into the house.
Right now we put the stuff we want disinfected in the garage with a fan running, run the ozone generator for 5 minutes, then let everything sit for an hour until the ozone is gone (and viruses too, hopefully). UPDATE: I've been putting items in a large bag, then filling the bag with ozone instead of filling the room.
The ozone generator is a common Chinese one from AliExpress (search for "ozone generator". The fan is a cheap $10 120V muffin fan. Controlling them is a timer from a toaster oven. The timer is important because you don't want to go into a room filled with ozone.
There's holes at the bot
