How to choose an exhaust fan for the bathroom Quakertown Electrician

 Size. First, you need to know what size you will need. Bathroom fans should have 1 CFM (cubic feet per minute) for every square foot of floor space in the bathroom. 

In other words, if your bathroom floor area measures 70 square feet, choose a fan with at least 70 CFMs to get the right amount of ventilation.

After you know what size you are after, there are 3 styles to choose from:

  1. Ceiling-mounted fans are installed in the ceiling and vent into the attic or out through the roof.
  2. Wall-mounted fans are mounted on the external wall of the house and generally are used when there is no practical way to vent through the roof; for example, a first-floor bathroom.
  3. Remote fans have a fan unit located in a remote location such as the attic; duct work connects the fan to an opening in the bathroom ceiling covered by a grill. Inline fans are often used in homes where one fan vents multiple bathrooms, or to have multiple vents in one large bathroom.

Some other things to consider

Once have you the necessary exhaust fan the fits your bathroom’s needs, here are some details you may want to look into….

  • Noise Level: Fan noise is rated by sones—a scale that represents degrees of loudness. A rating of 0.5 to 1.2 sones means the fan is exceptionally quiet. Ratings of 1.5 to 2.0 sones is very good. Fans rated in excess of 4.0 sones tend to be noisy.
  • Fans with heaters: This adds a little extra warmth for those chilly days.
  • Lighting: some fans come with overhead lighting.
  • Night light: equipped models use a low-wattage light to help you find your way in the dark.
  • Built in motion sensor:  turns on the fan when someone enters the bathroom. The fan speed can be pre-set to a low volume to remove the moisture of everyday tasks, such as shaving, and switch-activated for high-volume tasks, such as showering.
