Yes, gas stoves do need exhaust fans, even if they don't have open flames like electric stoves do. Gas stoves produce combustion byproducts such as carbon monoxide, nitrogen dioxide, and other potentially harmful pollutants when they burn natural gas. These byproducts can be released into the air inside your home, leading to indoor air pollution.
Having an exhaust fan above your gas stove helps to remove these pollutants and improve indoor air quality by venting them outside. The exhaust fan serves two main purposes:
Removing odors: Cooking with gas stoves can produce strong odors, and the exhaust fan helps to dissipate these smells, making your kitchen more pleasant.
Ventilation of pollutants: As mentioned earlier, the combustion process in gas stoves generates harmful byproducts. The exhaust fan helps to pull these pollutants out of your kitchen and prevent them from accumulating in the indoor air, reducing potential health risks.
It's essential to have the exhaust fan properly installed and regularly maintained to ensure it functions effectively. Additionally, consider using the exhaust fan whenever you cook on the gas stove to keep your indoor air clean and safe.
