How effective is your Bathroom Exhaust Fan?

For obvious reasons, bathrooms can be major sources of moisture in homes. And where there is moisture, there is the possibility of growing mold in the bathroom. A bathroom exhaust fan can be essential in removing excess moisture and keeping bathrooms ventilated, but how do we know if our exhaust fans are working properly? Just because we can hear them doesn’t necessarily mean that they are effective.

Ventilation is key to reduce Mold in the Bathroom

A simple way to test your fan’s suction is to take a single square of toilet paper and place it along the fan vent while the fan is running. If the fan holds up the toilet paper, then the fan is working properly. Keeping the bathroom door open while running the fan will allow for air exchange from other parts of the home. It is also important to make sure that the exhaust fan is vented outdoors.

Try using bathroom exhaust fans for 15 minutes after using the shower to help move humid air out of the living space. 15 minutes may be longer or shorter than required to keep your bathroom dry, depending on the bathroom size, building materials, windows, etc. It may also be a good idea to install a timer switch in bathrooms which will automatically shut off the exhaust fan after a pre-set amount of time.
