Average tasks like showering, bathing and shaving can put home-damaging humidity into the air in your Derby home. There’s good news though—a modest bathroom ventilation fan can protect you from warped wood, mold growth, cracked drywall and other trouble 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? Giordanos Heating and Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they work more quietly and effectively than ever before. You’ll find a large range of choices, from simple 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 getting out through your ventilation. While you can find a lot of bells and whistles to choose from, the most imperative aspect of your fan is whether or not it’s large enough to do its job.
Rated by the cubic feet per minute (CFM) of air they push, 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 at least as high as the number of square feet in your bathroom. Thus, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be sufficient.
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 use HGTV’s tips for bathrooms larger than 100 square feet – establish your CFM requirements by toting 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
