Summary: I installed this fan in my garage since it would vent towards the side of my house (and my neighbors) and noise was a paramount issue. Though not totally silent outside (likely due to the air passing through the rigid duct) it is super quiet inside. More importantly it provides enough air circulation to allow me to work in the 3500sq ft garage. The hot, stuffy stale air environment is gone!
Pros: Easy To Install, Powerful, Quiet, Sleek Design
Summary: Very quiet fan. Fan requires a larger hole in the ceiling than a standard bathroom fan - so requires some planning and effort during installation. Fan has greatly improved humidity problem in our bathroom.
