Rated 4.1 out of 5 by 22 reviewers.
Rated 5.0 out of 5.0 by Works great in our hot tub room. I installed this fan in an unheated enclosed 12 x 15 room under my deck, and it works so well that most of the condensation from the hot water is now immediately sucked out even when it is below freezing outside. Definitely a good choice! March 6, 2013
Rated 5.0 out of 5.0 by Easy installation. Great power for the price. We needed a ventilation fan in our new kitchen. The oven is located in the middle of the room relative to the fan, so we knew we wanted something with power to pull air from the entire space. This 270 CFM fan was perfect for the space. It has a slightly larger face than other units, but looks nice on the wall. And the power is great. The noise is noticeable but the box was clear so it met my expectations. You can't expect a lot of power without some noise with it. For the purpose, the noise is completely acceptable and not so loud that you can't talk easily over it. The installation was easy. There is one point I would make on the instructions. It indicates to cut a square hole for the fan through your wall. We saw no reason not to cut a round hole to make minimize draft and potential visible cut lines. The round hole worked perfectly. July 23, 2013
Rated 5.0 out of 5.0 by Quality Kitchen exhaust fan Very easy to install. Replacing a 50 year old NU-TONE of same design over a stove. Slightly smaller in diameter but a new install should go in very easy. I was impressed with the quality which matches commercial fans costing 5 to 10 as much. If exhausting cooking fumes, I would recommend installing the optional round grease filter as a major problem with the old fan was keeping it clean. The new one is very easy to clean. Only drawback is that it is still on the noisy side for use in a home. September 3, 2014
Rated 5.0 out of 5.0 by Seems to be working as expected bought this for my dog grooming room. I used have lots of hair attached to my face or head when i blow dry my dogs. But now it seems near no hair when the fan is used during blow dry. Like it March 24, 2015
Rated 5.0 out of 5.0 by Moves some air!! Installed this in about 2 hours.Make sure you look for studs before cutting a hole in your wall. I used a stud finder to locate a stud,right in the middle of where I wanted to mount. Had to frame out , Awesome fan really moves some air. Can literally feel the air coming through the window while it is running. Well made and a good value! July 2, 2013
Rated 4.0 out of 5.0 by Just what I wanted Good noise level for size of fan. Hard to find wall exhaust fans any more. January 27, 2015
