## Description

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. TD-BF-01 110CFM1.0Sones. Ventilating for bathroom up to 110 Sq. Ft TD-BF-02 90CFM0.8Sones.

Review: This 80 CFM one is the right size for the our washroom, but this is so quiet and a little smaller than the old one it replaced, I think I could have probably fit the higher CFM one and it would have still fit and be quieter and an upgrade too. It has been working fine for some time now, and I have no complaints.
Review: Funciona perfectamente, se instaló en un cuarto de máquinas de alberca.
