Why This Matters

Your bathroom exhaust fan removes humidity that causes mold, mildew, and peeling paint. A dirty fan moves less air, which means moisture stays in your bathroom longer.

Signs your fan needs cleaning: Runs louder than usual, bathroom stays humid longer, visible dust on the cover, or you can't remember the last time you cleaned it.

Step-by-Step Cleaning

1

Turn off the fan

Switch off at the wall switch. For extra safety, turn off the bathroom circuit breaker.

2

Remove the cover

Most covers have squeeze clips - gently pull down and squeeze sides to release. Some have screws.

3

Wash the cover

Soak in warm soapy water for 10 minutes. Scrub with soft brush, rinse, and let dry completely.

4

Vacuum the fan and housing

Use vacuum with brush attachment to remove dust from fan blades and housing. Don't touch motor.

5

Wipe remaining dust

Use damp cloth to wipe fan blades and visible surfaces. Let everything dry before reassembling.

6

Reinstall cover and test

Snap cover back in place. Turn on fan and verify it runs smoothly and quietly.

Test Your Fan's Suction

The toilet paper test: Turn on your fan and hold a single sheet of toilet paper up to the cover. A properly working fan should hold the paper against the grill with suction.

If the paper falls, your fan may need cleaning, the ductwork might be blocked, or the fan motor could be failing.

Pro Tips

  • Clean every 6 months: More often if you have pets or lots of dust.
  • Check the duct: If fan still seems weak after cleaning, the exterior vent may be blocked.
  • Consider upgrading: Old fans (15+ years) are much louder and less efficient than new ones.
  • Run it longer: Keep fan running 15-20 minutes after showering for proper moisture removal.
