Rated 3.6 out of 5 by 34 reviewers.
Rated 4.0 out of 5.0 by Good quality Unit is several years old. I have replaced the motor once. February 6, 2015
Rated 2.0 out of 5.0 by moves air-- yes; beware you don't get a "bad" one We had a contractor install two of these units into two bathrooms on the same day. One ran quitetly and was fine. The other "rattled" and was annoying. Because they are the same unit, I was able to swap the motor part between the two fans--- I wanted to find out if it was the installation that was making it rattle, or if it was the actual fan. Sure enough, the quiet fan was quiet in the second location; the rattle fan rattled in the second location. I went off to HD to get a third model of this unit--- and guess what--- it rattled WORSE than the original rattling fan. What can I say--- when it works, it's great--- when you get 2 in a row that are not performing--- you become very disappointed with this product. March 30, 2011
Rated 5.0 out of 5.0 by a good fan this fan is easy to install, is sufficiently forceful and has a quiet run March 25, 2015
Rated 5.0 out of 5.0 by Nutone 80 CFM A few hours ago I installed this exact fan. To pull out the existing Broan 50 CFM fan, install this fan, and to clean up, it took me a total of 3 hours. Our bathroom is 60 square feet and after taking a really hot 15-20 minute shower, only 6 inches of condensation fogged the upper portion of our 3 foot mirror over the sink. The condensation was completely gone after 5 minutes. This fan CAN BE installed both with and without having to go into the attic. The sound level is perfect and it only draws half of an Ampere! I would definitely purchase again. Good rule-of-thumb: calculate your square footage, add 20, and round that number up to the nearest whole number divisible by 10 to equal the CFM of the fan your about to purchase. (For example, 52 square feet + 20 = 72, which rounds up to 80 CFM.) April 27, 2010
Rated 5.0 out of 5.0 by Great upgrade from contractor grade Great bath fan. Not much modification needed to install in place of contractor grade fan. September 21, 2014
Rated 4.0 out of 5.0 by Best Fan for the Price My 92 year old mother needed a replacement fan for her bathroom. The cheap ones are noisy and the expensive ones are large and pricey. This fan is the perfect balance of quiet and economy. October 14, 2014
Rated 4.0 out of 5.0 by Great For Retro Fitting From Below Without Attic Access I found these reviews very helpful in selecting a fan to retrofit into a bathroom ceiling without attic access. Ease of install and access were critical. I had to replace and old ceiling fan that was mounted inside duct work, which was a tight space to work in. Out of all of the fans I researched, this fan was the most flexible. The size of the fan motor is small enough to fit in a tight space. I was able to use tin snips to modify the housing, without interfering with the function of the fan. By opening up the housing, it gave enlarged access for drill to create new mounting holes. I used sheet metal screws to mount the fan to the duct work. I used two fans side-by-side to create 160 CFM. This installation would have been impossible with all the other fans at home depot, as their housing size would leave no working space to fit your hands into. My dual fans run well with no vibrations, or squeaks - which is amazing considering my sheet metal work to retro-fit and create a new way to mount. This fan has a noticable hum when it runs, and it is a bit louder that some of the other "ultra quiet" fans. However, it is less noisy than the fan it replaced, and it really moves the air. No fog at all on the mirror even when shower running for an extended period of time. I would recommend that this model be selected if you are installing in a tight space with no access from above, The design allows mounting in atypical situations, and it is easy to modify to suit your installation needs.

Rated 2.0 out of 5.0 by Noisy - Cover does not stay up easily I have this in one bathroom and a Panasonic fan on another one. This sounds like a jet fighter compared to the Panasonic. I am in process of removing this cheap fan (placed by contractor) and replacing it with a Panasonic, which is not much more expensive on Amazon. Best that I can say is that it works. July 27, 2014
