To eliminate odors in houses, plug in the ozone generator unit and turn it on. Based on the severity of the odor, you may need to have it going all night. Ensure that your air conditioner or heater is running, so the treatment can go all throughout the house easily, and make sure that all of the cabinets, drawers, closets and doors are wide open. This will allow for better ventilation not only all throughout the house, but through every crevice possible. If a certain closest is particularly the one with the worst odor, the generator will see to it, as long as the door is wide open.
After the cycle has finished running its course, check to see whether or not the odor is completely gone. If not, run the cycle once more.
