Broan 676 110-CFM 4.0-Sones Ceiling Mount Ventilation Fan

I bought this to replace an old fan that the builders had installed (my old one was only rated at 50cfm). I needed a new one because I was getting condensation on the bathroom walls since the old one was not moving enough air. I was able to install this in about 20 minutes from below and it works great. Perfect sound level to wash out any unwanted bathroom noises but not to loud so it's not annoying. It certianly moves a lot more air than the old fan. I liked this fan so much I bought another one and installed it in my other bathroom. Don't forget to insulate the cracks between the drywall and fan fixture to eliminate heat loss and help secure the fan (which helps reduce movement/noise). I used spray foam which worked great. I let it dry over night and then used a razor to scrape it flat and neat. Also, to make sure the bathroom fan acutally has air to move there must be a gap on the bottom of the bathroom door so the fan can pull air from outside the bathroom under the door...Read more

I bought this model because the price was right for a spare bath, and it was the right size to replace the old one. I didn't care that it was 4.0 sones. How loud could it be for the length of time it runs.? But the first fan received vibrated on the spindle and my electrician suggested I get a replacement. I did. Amazon was amazingly fast with the replacement and sent it out before they received the old one. The second one was fine and suits my needs. I recommend plugging these fans into an outlet before installing in the ceiling. If I had, I could have had the replacement before I got the electrician in and pay him for two trips.

This bathroom ceiling fan is much quieter than the previous fan. I am pleased with the sound. However, I found that mounting the fan with the attached mount placed the exaust 180 degrees from the exaust ventpipe, already installed. If I had had access to the fan from the attic, this would not have been a problem; I would have installed a cross mount for positioning the fan correctly, lining up with the ventpipe. Also, the fan exaust was 4in. in diameter. The original was 3in.
