Everyday tasks like showering, bathing and shaving can put home-harming humidity into the air in your Thedford home. There’s good news still—a simple bathroom ventilation fan can protect you from deformed wood, mold growth, cracked drywall and other problems related with a humid bathroom.
Even if you have ventilation fans in your bathrooms, do you know if they’re the right size? Are they as quiet and energy efficient as they could be? Taylor's Heating & Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and sleek and they operate more quietly and effectively than ever before. You’ll find a hefty range of options, from average fans that will get the job done to fans with fitted heat lamps, motion sensors and heat-exchanger ventilation that helps avoid warmed air from escaping through your ventilation. While you can find a lot of bells and whistles to select from, the most critical characteristic of your fan is whether or not it’s big enough to do its job.
Rated by the cubic feet per minute (CFM) of air they transfer, a bathroom ventilation fan should be able to replace the air in a bathroom at least eight times an hour. With a standard 8-foot ceiling, your ventilation fan should have a CFM rating almost as high as the number of square feet in your bathroom. So, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be satisfactory.
If you have a taller ceiling, the equation gets a little more difficult. You’ll want to multiply the width of the room by its height and length, divide it by 60 and multiply by 8. Or, to keep it simple, you can follow HGTV’s guidance for bathrooms larger than 100 square feet – determine your CFM requirements by adding 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
