i'm wondering how do people even know what ozone smells like?

Ever been next to an electric arc discharging? The odour you can smell is Ozone.

It's the smell of photocopiers or laser printers operating.

I used to have a hot tub and it had an ozone generating device for killing bacteria. I loved the smell but people here are saying if you can smell it you are getting dangerous levels of it. :(
