Ozonepurifiersonline.com offers several Light Commercial Ozone Air Purifiers that are designed to deal with heavy odors and mold.

The LC Series units are specifically designed to eliminate heavy odors.  They can be used in basements to rid the mold and mildew odors; in Hotel / Motel Rooms to rid the odor of Tobacco; in rooms that have fire or water damage odors; and in cars, trucks, boats or RV's to remove stale odors.

The LCS Series is the Light Commercial units with a Puristat Sensor.  The Puristat Sensor is an air quality sensor that detects very low levels of odor, toxins, and pollutants.  When the toxins and odors are neutralized, the sensor puts the unit into a stand-by mode until the quality of the air changes again.  All sensored units operate manually as well.
