Ozone

In case you're wondering, the people at the front desk of my apartment have given me an Ozone machine. Apparently I leave this on in my apartment and it gets rid of malicious odors. I'm not sure if the "Ozone" in the machine's name has anything to do with the one that's depleting the stratosphere, and I chose not to ask, since I don't want to risk feeling guilty until I've gotten rid of this non-dead-person smell.
