Considerations of Installing a Bathroom Exhaust Fan

Now that we have introduced our readers to the benefits of installing a bathroom exhaust fan, let’s have a look at the factors that should be considered when installing an exhaust fan in the bathroom.

Type of Exhaust Fan

There are two major factors to consider when selecting an exhaust fan for your bathroom – CFM and Sone.

  • CFM or cubic feet per minute – This indicates the power of the fan. Exhaust fans may have a CFM of 50 to 1000. Consider the size and ventilation system of your bathroom and choose an exhaust fan that matches your ventilation requirements. Generally speaking, most bathrooms require exhaust fans with a CFM of less than 200.
  • Sone – It is the measure of loudness or the sound an exhaust fan makes. Exhaust fans may have a sone of 0.5 (almost noiseless) to 4 (sounds like a television). You may require a noisy fan if the bathroom is located near the public areas of your home to provide privacy against toilet sounds.

Size and Specifications of the Bathroom

As already discussed, size of the bathroom dictates your selection of an exhaust fan. A general principle for selecting an exhaust fan for a bathroom is to calculate the square footage of the area and choose a fan with the same number of CFM. For example, if your bathroom is 6’ X 8’, you will need an exhaust fan with 48 or 50 CFM.

However, if your bathroom has an area of 100 square feet or more, you will have to assign CFM capacity to separate fixtures.
