How to choose your Bathroom Fan?

  What is a sone rating?
 Sones, or the sone rating, is a term used to describe sound levels. Lower sone ratings are found on quieter fans. Higher sone ratings indicate a louder bathroom fan.

 What is CFM? 
 CFM (Cubic Feet per Minute) measures fan air movement. CFM increases as air movement increases. A higher CFM is best for a larger bathroom; a lower CFM may be adequate for smaller spaces.
