Oust® Air Sanitizer is not another room spray or air freshener. It actually kills the odor-causing bacteria in the air. That means it snuffs out the annoying smells caused by bacteria before you smell them. It is also specifically formulated to kill odor-causing bacteria in the air. Spray it in the air!
