What are Bathroom and Kitchen Exhaust Fans Really For?

Exhaust fans in bathrooms and kitchens do exactly what they are supposed to do. They pull unwanted air particles out of your home and push them straight outside! But there’s a problem: sometimes hot or cool air that’s outside can come in the same way! In this post, we’ll explore ways to prevent that from happening.


In bathrooms, exhaust fans help remove humid air out of the room. That’s why it’s a good idea to turn it on during or after a long, hot shower. All that steam left in the room can cause mold and mildew on the wall and tiles. The exhaust fan helps get rid of the steam so it doesn’t have time to do damage.

The kitchen exhaust fan helps eliminate steam, and even smoke, that develops when cooking. It also serves as a safety feature for those with a gas stovetop, by keeping flammable gasses away. During the summer, it can help keep your kitchen cool, even when cooking a hot meal.


Exhaust fans should have a backdraft damper installed where the duct exits your home. These usually come with installation, but sometimes they are broken or need to be replaced. This can happen if debris gets jammed in the damper, leaving it open even when the exhaust fan is not in use. Not only can air get in, other debris, and even bugs can get in. The flaps can eventually get rusted and should be occasionally replaced. If you notice air coming in through your fan, that’s also a reason to get it checked out.
