Ozone smell

[Poconos]

As I remember from years ago ozone had a somewhat sweet smell. I also remember that if the concentration gets anywhere near the hazardous level you wouldn't be able to stand the smell. I used to use an electrostatic filter in my Jersey house and there were occasional smokers and I could crank up the voltage and generate lots of ozone and get rid of the smoke odor.

Ozone, true ozone at a certain level is toxic. It's a weird oxygen molecule. Oxygen usually bonds in pairs, O2, but Ozone is 3 atoms, O3.
