Ordinary tasks like showering, bathing and shaving can put home-harming humidity into the air in your Bossier City home. There’s good news however—a modest bathroom ventilation fan can keep you from deformed 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 proper size? Are they as quiet and energy efficient as they could be? Central Aire Heating & A/C Inc is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they work more quietly and economically than ever before. You’ll find a large range of selections, from classic fans that will get the job done to fans with built-in heat lamps, motion sensors and heat-exchanger ventilation that helps block warmed air from escaping through your ventilation. While you can find a lot of bells and whistles to pick from, the most critical feature of your fan is whether or not it’s big 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 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 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 satisfactory.
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 follow HGTV’s guidance 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.
