"Thanks to the Sensaire technology, Broan's humidity-sensing fans detect an increase in humidity at the ceiling, where it's most prevalent, unlike humidistats, which only detect simple humidity," said Mantha. This feature makes Broan's fans more effective at protecting bathrooms from mold and mildew, which can result from excess humidity.

According to the company, homeowners and property managers will appreciate the fact that Broan's humidity-sensing fans are automatic - once the room's relative humidity is set, the fan will automatically turn on to exhaust excess moisture and turn off once the job is done.
