Ordinary tasks like showering, bathing and shaving can put home-damaging humidity into the air in your Mobile home. There’s good news though—a simple bathroom ventilation fan can protect you from distorted wood, mold growth, cracked drywall and other problems connected 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? Farnell Heating & Air Conditioning Inc 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 large range of choices, from average fans that will get the job done to fans with integrated heat lamps, motion sensors and heat-exchanger ventilation that helps block warmed air from getting out through your ventilation. While you have a lot of bells and whistles to pick from, the most critical characteristic 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 replace the air in a bathroom at least eight times an hour. With a typical 8-foot ceiling, your ventilation fan should have a CFM rating about 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 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 advice 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.
