The Bio-Pro Research Odor Fogger is a total release fogger that destroys odors on contact. This is not an air-freshener; it neutralizes and eliminates odors in a room up to 20’ × 20’. This will not harm clothing, furniture, or electronics left in the room. Good for removing smoke odor from a room within 5 minutes before a non-smoking fastidious guest comes. Also can remove heavy or stubborn odors from kitchen storage, smelling industrial premises, food factories, fishing boats etc.
