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 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 a good fan this fan is easy to install, is sufficiently forceful and has a quiet run March 25, 2015
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 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 2.0 out of 5.0 by Room for improvement I purchased and installed this fan Saturday. The whole project wasn't too difficult, but it took a while because I had to install a roof vent and duct work to vent the air out of the attic, and do some electrical work since my bathroom did not previously have a fan. Like: - I like the power of the fan. It moves a good deal of air and clears the humidity out of the bathroom. This fan does its job well. - I like the noise of the fan. Not very loud, but not silent either. ... Maybe it could be just a tad quieter, but overall I'm very pleased with the sound level. Dislike: - The unit I bought rattled horribly when I first ran it! I was very unhappy when I first turned it on and I was about to take it down to take it apart or take it back. However, I first gave it a good smack on the top of the unit and the rattle stopped and it sounded as it should. ... I recommend testing the unit by plugging the motor cord into an outlet before you install it to make sure it works and sounds as you'd expect. - The metal housing is not even close to airtight. I recommend using NASHUA aluminum duct tape to seal the top edges of the housing so it doesn't blow the humid air that it vents into the attic. (You can also use tape to cover other screw holes and edges in the housing to better seal the unit.) - The fan was about $7.50 more expensive in the store than it was listed for online. Overall, I'm pleased with the unit. I'd buy it again as I didn't see another fan-only unit that looked better in this price/performance range, but since I had to seal the unit, it rattled really bad out of the box, and it wasn't cheap I can't give it more than 2 stars.

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.
