Average tasks like showering, bathing and shaving can put home-harming humidity into the air in your Lodi home. There’s good news still—a modest bathroom ventilation fan can keep you from distorted wood, mold growth, damaged drywall and other issues related 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? Tokay Heating and Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they operate more quietly and efficiently than ever before. You’ll find a great range of choices, 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 critical characteristic 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 push, a bathroom ventilation fan should be able to replace 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. Therefore, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be satisfactory.
If you have a higher ceiling, the equation gets a little more complicated. 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 increasing 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
