Ok my wife is cleaning up houses and Appointments that had Smokers.

She said the best way to take smell and all out is to get a machine that takes all the Oxygen out of the air.

I’ll bet this is a CO2 machine. I’m thinking if it is yea get it.

Probably ozone machine, I use one in a sealed closet for daily items like clothes, shoes, etc. Not safe to breathe.
