Rated 3.7 out of 5 by 23 reviewers.
Rated 4.0 out of 5.0 by This fan worked out great. Easy install. Setup to turn on automatically. Works exactly the way i anticipated. December 11, 2012
Rated 1.0 out of 5.0 by I think we got a defective product.... Was able to get it installed - but won't come on. In the process of exchanging it for another model. Was installed by a pro - but couldn't get it to work. June 27, 2015
Rated 1.0 out of 5.0 by Doesn't work nearly as well as reported I have used it and have tried adjusting the settings for nearly a year. It continues to underperform. It keeps on turning back on, long after the shower has been used and the humidity is gone. The time adjustment seems to be too short or too long of a running time, 10 min or 60 min. But 10 min time running feature will keep on resetting for nearly an hour. The strength of the fan seems unimpressive, cheaper fans seem to work better. I would not recommend a fan with a humidstat sensor, technology has not improved it enough for practical purposes yet. December 8, 2014
Rated 1.0 out of 5.0 by Automatic glitchy I am trying to rewire our fan to manual because the auto feature turns in on sometimes even when the humidity is below 30%. Newtone doesn't have an answer for that. January 17, 2015
Rated 5.0 out of 5.0 by Buy this fan I read the reviews - both the pros and the cons. I have not experienced any of the "cons" that others listed - other than it carries a stiff price. However, it's well worth it. This fan does exactly what Broan/NuTone claims. The installation was easy. The wiring was easy. The fan is QUIET! After crawling around in the attic, I was in a hurry to try out the auto-sensing of humidity. I didn't hear it come on. Probably because it was so quiet that I could hear the radio that I have in the bathroom. After turning off the water in the shower, I heard the fan. The mirror was fogged when I stepped out of the shower. By the time I had dried off, the mirror was clear. The fan continued to run for the programmed 20-minutes past the point that the humidity dropped below the sensing level. I highly recommend this fan. November 26, 2011
Rated 2.0 out of 5.0 by Beware The bells and whistles that this fan has are wonderful. Be aware that the wiring does not match the instructions. Therefore even hiring a professional to install this unit will be a challenge. The timer and humidity feature on my unit still won't work. So I don't have the bells and whistles that I thought I was purchasing. Now that it's installed, it's hard to return it!!! Would have suggested another unit, if I had it to over again! April 3, 2011
Rated 5.0 out of 5.0 by Simple to Install, Simple to Operate, Simply Simple I grew tired of fogged bathroom mirrors and windows, and the mold and mildew threat such clinging moisture encourages. The solution was the QTXEN110S Humidity Sensing Bathroom Fan. I recommend going with a 6-inch duct to maximize air flow. The only oddity I encountered was the way in which you activate the fan to exhaust odors; namely: flip the wall switch from ON to OFF, pause for a second or two, and then flip the switch from OFF back to ON. Even with the company’s suggested two-function switch, you still have to flip a switch back and forth. If they had invested an additional fifteen bucks in design and development, they could have offered a push-button solution that would have been more elegant for such a sophisticated unit. And, yes, I would have paid the extra fifteen bucks. That one issue aside, I am very satisfied with the unit’s humidity-sensing feature, near-silent operation, and efficiency December 13, 2011
Rated 5.0 out of 5.0 by outstanding product I'm glad every time it kicks in. I couldn't be happier with my purchase. I recommend it to everyone. September 15, 2014
