Everyday tasks like showering, bathing, and shaving can put home-harming humidity into the air in your Huffman home. There’s good news, however—a straightforward bathroom ventilation fan can save you from warped wood, mold growth, damaged drywall, and other trouble associated 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 noiseless and energy efficient as they could be? Air Houston Mechanical LLC is here to answer your questions.
Today’s bathroom ventilation fans are small and modern, and they operate more quietly and efficiently than ever before. You’ll find a great range of selections, from average fans that will get the job done to fans with built-in heat lamps, motion sensors, and heat-exchanger ventilation that helps prevent warmed air from leaking through your ventilation. While you have a lot of bells and whistles to select from, the most important feature of your fan is whether or not it’s large enough to do its job.
Graded by the cubic feet per minute (CFM) of air they transfer, a bathroom ventilation fan should be able to swap out the air in a bathroom at least eight times an hour. With a normal 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 sufficient.
If you have a taller 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 easy, you can use HGTV’s tips 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.
