How to Clean a Bathroom Exhaust Vent Fan
By: Danny Lipford
It’s very important to have an exhaust fan that’s vented to the outside in every bathroom in your home, and to run it whenever you shower or bathe and for 15-20 minutes afterward to remove excess moisture that can cause mold and mildew to form.
An average sized bathroom vent fan that’s used one hour a day will exhaust over 2,000,000 cubic feet of air a year, or the equivalent of the air inside 1,000 homes.
As air is drawn through the fan, dust builds up on the grille cover and the fan motor over time. Cleaning the cover and motor housing every six months to one year will remove most of the accumulated dust. Here’s how to clean your vent fan.
To clean a bathroom vent fan:
- Turn the fan off at the switch or circuit breaker.
- Remove the cover by pulling down until the cover is several inches from the ceiling. Press the spring loaded wire clips, found on two sides of the cover, together then remove the clips from the slots in the fan housing.
- Place the fan cover on a towel and use a vacuum cleaner equipped with a bristle brush dusting attachment to clean the cover and grille thoroughly both inside and out.
- Use the dusting attachment on the vacuum to clean inside the fan housing and around the motor. For hard to reach spots, use a crevice tool on the vacuum.
- Reinstall the fan cover by press the clips on the fan cover together, and slip them over the slots in the fan housing. Finally, push the fan cover up until it seats against the ceiling.
