Everyday tasks like showering, bathing and shaving can put home-harming humidity into the air in your Odessa home. There’s good news however—a simple bathroom ventilation fan can protect you from warped wood, mold growth, cracked drywall and other trouble connected with a humid bathroom.
Even if you have ventilation fans in your bathrooms, do you know if they’re the correct size? Are they as noiseless and energy efficient as they could be? Redhawk Heating & Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they work more quietly and effectively than ever before. You’ll find a great range of options, from average fans that will get the job done to fans with built-in heat lamps, motion sensors and heat-exchanger ventilation that helps avoid warmed air from escaping through your ventilation. While there are a lot of bells and whistles to pick from, the most important aspect of your fan is whether or not it’s big enough to do its job.
Graded by the cubic feet per minute (CFM) of air they move, 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 at least as high as 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 satisfactory.
If you have a larger 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 advice for bathrooms larger than 100 square feet – establish your CFM requirements by adding 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
