Rated 4.2 out of 5 by 33 reviewers.
Rated 4.0 out of 5.0 by Does what it should Have a small closet inside of the laundry room that we use for the littler box. Being such a small room, it didn't take long for the odor to seep out into the laundry room. With the closet sharing a wall with the garage, I decided to vent the room into the garage. Not wanting the fan to run 24/7, I used a timer switch that can be set when needed. July 25, 2013
Rated 5.0 out of 5.0 by Easy to instal as a direct replacement. Used to replace an existing 40 yr old unit when re-siding the house. Same easy electrical connection and through-the-wall fit. Outside Vent and inside Grill required no changes to be made to mounting surfaces. Quick and easy. December 17, 2013
Rated 5.0 out of 5.0 by Good Buy Easy to install. Not too loud. Works for my NYC apartment. July 7, 2015
Rated 4.0 out of 5.0 by Works well, and it is quiet The fan works well. It does require drilling a couple of 6" holes so be prepared for that. The electrical hook-up requires removing and replacing the motor, but that is easy. All in all, I am happy with the product, and the pricing was very good. June 10, 2013
Rated 2.0 out of 5.0 by Noisy and somewhat diificult to wire This fan does exaust very well but is quite noisy because of the grill design the wiring box is a bit tricky but can be done if you are patient. March 4, 2014
Rated 4.0 out of 5.0 by It was used for a bathroom exhaust fan and eliminates the shower steam effectively. The installation was easy and quick One issue that should be addressed is the exterior damper. The three flap shutter design allows light and air to flow freely into the house. I would consider a redesign to have a tight backdraft flap and a hood to reduce light from entering. My customers are experiencing cold air blowing through the fan when not in use. I am currently looking for an alternate solution to solve this issue. February 23, 2012
Rated 5.0 out of 5.0 by Exactly what I needed. The fan was delivered quickly and was easy enough to install. It runs quietly and does the job. When someone opens and closes my front door to the house (small guest house) I can hear the outside flap open and close lightly when in the bathroom where the fan is mounted. Not a big deal to me though. Just thought is might be worth mentioning. Happy with my purchase. June 2, 2015
Rated 4.0 out of 5.0 by Wall Exhaust Fan I purchased this wall exhaust fan to replace an existing fan in our 1/2 bath. The existing fan was extremely noisy. I found when I was looking for a replacement fan that most wall fans were rated "pretty noisy". This one was one of the few that was not. We recently installed it and the difference is noticeable. It was definitely worth it. August 21, 2014
