110-CFM bathroom fan operates at 0.7 sones * Sensaire technology detects rise in humidity * 6-inch ducting for superior performance * Automatic shut-off time adjusts from 5 to 60 minutes * Motor engineered for continuous operation If you only remember to turn on the fan after you've stepped into the shower, or if the kids can't be trusted to remember at all, this QTXE110S Ultra Silent humidity-sensing fan from Broan offers a convenient solution. It also works well for busy families that need to leave the house before all the humidity is properly vented. Equipped with Broan's exclusive Sensaire technology, the fan detects when steam and humidity levels quickly increase at the ceiling, then it turns on automatically to help return the room to normal humidity levels, which in turn helps prevent mold and other cosmetic and structural problems associated with excess moisture. Even more, it turns off automatically when the job is done (auto shut-off time is adjustable from 5 to 60 minutes). Sensitivity and run-time controls located beneath the drop-down grille can be easily adjusted as needed with a screwdriver, or override the sensor anytime with the touch of a switch. Other details include 110 CFM, nearly silent operation at 0.7 Sones, Energy Star qualified, hanger bars for easy universal installation (fits 2-inch-by-8-inch construction), 6-inch ducting, and UL listed for use over bathtubs and showers (when connected to a GFCI protected branch circuit). Ideal for high-traffic bathrooms or a kid's bathroom, the Ultra Silent humidity-sensing fan's housing measures 10-1/2 inches long by 11-3/8 inches wide by 7-5/8 inches high, and its grille measures 13 inches long by 13-3/4 inches wide. Broan covers the unit with a three-year limited warranty.

I had been bothered by my rental house's the bathrooms moisture issues, there were black/green spots in the celling, renters don't care to turn on the fan when they take showers, even they turn on the fan, it's not strong enough to suck the moisture out, plus the noise, so I did lots of reserch and found this wonderful piece, installed it couple of weeks ago, and it works wonderful, absolutely no moisture anymore, and hardly to hear it, love it, purchased another one and now I can sit back relax...couple of..
Humidity sensing only works properly in the winter, when the background humidity is low. The rest of the year the fan turns itself on constantly, when bathroom has not been used. This happens even though the house has a central dehumidifier that keeps the background humidity below 50%. I set the sensitivity control on the fan to MIN but the problem remains. I had 3 of these fans installed when the house was built, and they all do the same thing. I ended up unplugging the humidity sensors.
I bought cheaper fans before and decided recently to buy this expensive one, but quiet and lots of CFM fan. The installation went very well, it wakes up automatically, which will be very useful in the kid's bathroom. And I have to say it is very quiet. I am really impressed. Quality seemed also much better. Even after long and hot shower not even single drp of water or fog on mirror. I would love to replace other fans now. I am glad I bought it. Money well spent. And the externel vendor selling it on Amazon..
