Place the unit in the room that is in question, preferably as close as possible to an open air vent. Turn on the Bio3Blaster ozone generator unit when you are leaving, so it can do its thing all night long. Have whoever is around first in the morning turn the ozone generator off, and open a window. This will allow a fresh circulation of air before you go about your business for the day. Allow the entire area to air out for at least an hour before anyone else comes into the room. If the odor still lingers on, repeat the cycle.
