Wait, I have an exhaust fan in my bathroom? Are you using your bathroom exhaust fan correctly?

Hopefully you not only know you have a bathroom exhaust fan, you are also utilizing it every time the bathroom is occupied. The main function of an exhaust fan is to clear unwanted contaminates such as moisture and odors from the bathroom. For a lot of people that means that when the mirror starts to fog up, they turn the fan on and as soon as they leave the room they turn the fan off.

Unfortunately that is not utilizing your fan the way it is designed. According to the Home Ventilation Institute (HVI) the exhaust fan should run for at least 20 minutes after the shower has been used. This ensures that the proper amount of ventilation has occurred. To simplify the process there are many timer options on the market today.

For existing fans, you can simply add a timer wall switch. This can typically be done in less than an hour by a homeowner with some electrical wiring knowledge. Air King always recommends consulting a professional if you are unsure about any aspects of the installation.

If you are looking to purchase a new exhaust fan, there are many models that include motion sensors that detect when you leave the room and allow the fan to run for the preset amount of time. Both of these option simplify the process so you are not trying to figure out how long the fan has been running or need to remember to go back into the bathroom to turn the fan off.
