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.

  • Very quiet efficient fan!
Size: 80CFM with Humidity Sensor
Great fan for small bathroom. No issues installing as a replacement. I am impressed on how quiet it is. Goes a great job!

  • Great fan!
Size: 80CFM with Humidity Sensor
I’ve been using the Tech Drive Quiet 80 CFM fan for a little while now, and I’m really happy with it. It’s super quiet—much quieter than I expected—and doesn’t bother me even when it’s running all day. The compact size is great for fitting into smaller spaces without taking up too much room. It works well to keep the air moving and feels efficient for its size. The only reason I’m giving it 4 stars instead of 5 is that I wish it had a few more speed settings or some additional features, but overall it does exactly what I need. If you want a quiet, no-fuss fan that fits small spaces, this one’s a solid choice. ... show more
