Everyday tasks like showering, bathing, and shaving can put home-damaging humidity into the air in your La Puente home. There’s good news though—a straightforward bathroom ventilation fan can keep you from warped wood, mold growth, damaged drywall, and other problems associated with a humid bathroom.
Even if you have ventilation fans in your bathrooms, do you know if they’re the proper size? Are they as quiet and energy efficient as they could be? Temp Air System Inc. is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth, and they work more quietly and efficiently than ever before. You’ll find a hefty range of options, from classic fans that will get the job done to fans with integrated heat lamps, motion sensors, and heat-exchanger ventilation that helps block warmed air from getting out through your ventilation. While you have a lot of bells and whistles to select from, the most critical aspect of your fan is whether or not it’s large enough to do its job.
Assessed by the cubic feet per minute (CFM) of air they move, a bathroom ventilation fan should be able to exchange 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 about the number of square feet in your bathroom. Therefore, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be adequate.
If you have a higher ceiling, the equation gets a little more complex. 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 heed HGTV’s advice for bathrooms larger than 100 square feet – establish your CFM requirements by increasing 50 CFM for every toilet; 50 CFM for each shower, bath, and combo; and 100 CFM for each whirlpool.
If you’re not sure if your bathroom ventilation fan is the correct size, or you know it’s come to the point for a new one, give the professionals at Temp Air System Inc. a call. We’re here to help you guarantee you have a ventilation fan that will run hard to guard your home and keep it comfortable.
