Is a higher CFM better?
Understanding Whole House Fan CFM
Cubic Feet per Minute or CFM is the amount of cubic feet of air per minute the fan moves. The amount of power a fan has depends on this measurement. The higher the CFM is, the more powerful the fan is.
What happens if CFM is too high?
Wasting Energy With Excessive Ventilation
Increased CFM will not dry out the bathroom any faster, so the fan will still have to run for the same amount of time. However, since the airflow is higher a lot more energy is lost.
What CFM is the quietest?
The quietest standard-noise fan can only manage to generate 33 CFM per 1 sone. All the selected whisper quiet bathroom fans in the table can generate more than 100 CFM per 1 sone; that’s how much quieter they are than a standard-noise fan.

What is a good CFM airflow?
Good CFM ranges from 4,000 to 5,000. Better ranges from 5,000 to 6,000. Best is over 6,000.
What fan speed is best for cooling?
What is this? According to HVAC professionals, the speed of an AC fan should be 400 CFM airflow per ton, though it can vary depending on the weather. A dry climate will require a 400 CFM per ton. A humid climate, on the other hand, needs a fan speed of 350 per ton.
Does higher CFM mean louder?
As CFM increases, sone (or volume) level increases. Range hoods from big box stores can be quite noisy even if they are a low CFM, because they are lower quality. But, a professional hood will be quieter at every speed, since it’s built with a more efficient motor, and better quality parts.
