The Panasonic WhisperLine fans are probably the best there is. Very quiet, easy to install. Wayfair had the lowest price.
I used the regular ceiling mounts in two bathrooms and a closet.
I used this inline fan, mounted in the attic, for exhausting the toaster and microwave ovens (they were mounted a little far from the range exhaust.
Strongly recommend using timers. It's difficult to hear them running.. Albert. Delray Beach, FL. Wed Aug 23 2017
