Using an Ozone Generator in a half occupied duplex

[Matt Stoltz]

I purchased a property with half of the duplex occupied while I fix up the other half. There is a smoke odor throughout the unoccupied unit. Would it be safe to lock off the upper unit while using the ozone generator? I am looking for effective methods to get rid of any smoke odors, and ozone generators seem to receive rave reviews. I want to make sure that it won't cause any harm to the lower tenants.

On the one hand i'm sure it would be fine, however why risk opening yourself up to complaints/issues? Just coordinate with other unit for when they'll be out of the house for an hour.
