If you are new to the world of indoor cooling appliances, you may wonder how to calculate the CFM of a fan. The best fans, after all, always include a CFM rating, in addition to other useful metrics. So, what is CFM, what are the benefits of buying a fan with an above-average CFM, and how to calculate the best CFM rating for your needs? Keep reading to find out.
CFM, or cubic feet per minute, is a metric that measures how effective a fan is at moving air throughout a space at its highest speed or power level. This is an important metric when shopping for the best ventilation fans, for instance. Also, if shopping for a whole-house fan, the CFM rating determines how quickly the fan moves air throughout the entire home.
No matter the CFM, make sure to clean the blades regularly to ensure proper balance and efficient operation.
So do you calculate a fan’s CFM rating? This is a process best left to professionals, even if you learned how to bypass a ceiling fan switch. You can, however, figure out an adequate CFM for your room or home, which comes in handy after learning how to install a ceiling fan.
