What is the primary purpose of using exhaust fans in odor control?

The primary purpose of using exhaust fans in odor control is to remove potential harmful gases from the environment. Exhaust fans are designed to facilitate the movement of air out of an area, which helps to dissipate and eliminate noxious and stale odors that could be caused by various contaminants. By expelling these harmful gases, exhaust fans help maintain a safer and more pleasant indoor air quality, which is especially important in environments where odors can pose health risks or discomfort.

While circulating fresh air and enhancing aesthetic smells may have their own benefits, the core function of exhaust fans directly relates to the removal of hazardous air pollutants, ensuring that spaces remain safe and odor-free. The introduction of new odors serves no purpose in odor control and is counterproductive to the goal of creating a clean and healthy environment.
