Trust the power of ozone to seek and destroy most types of odor in rooms large and small. The ScentLok Room Deodorizer emits a stream of ozone using innovative CycleClean technology, which moderates output with active and resting phases for maximum efficiency. As ozone comes in contact with smelly contaminants like bacteria, fungus and mold, it removes the offensive odor through the process of oxidation. The ozone then reverts back to oxygen after being used. Intended for use in unoccupied spaces only. Includes 12-volt DC power supply for the Large, and 110-volt only for Small, vehicle power adapter and transport tubing. Available: Small Room, Large Room.
