Essential Info

Prevent excess humidity and mildew in your home with an ultra-quiet bathroom fan that automatically helps to prevent lingering, excessive humidity. Regular humidistats located on the wall simply detect absolute humidity levels and are prone to false triggers, but the Humidity-Sensing Fan and 42-Watt Light uses Broan's proprietary SensAire® technology to detect rapid increases in moisture levels at the ceiling, where steam and humidity naturally rise. This high-performance fan features sensing circuitry that knows when to ventilate the room, so you'll never have to worry about turning the fan on.

    Hands-Free Operation
    The Humidity-Sensing Fan installs in place of a standard bathroom fan using the included mounting materials. Just beneath the drop-down grille are easy-to-adjust sensitivity and run-time controls. The auto shut-off time is adjustable from 5 to 60 minutes. Choose your preference, set with a screwdriver and forget it. The humidity controller automatically turns the fan on when the humidity increases rapidly or when it rises over a user-adjustable set point. This fan runs so quietly, you'll barely notice that it's running. Of course, you can always override the sensor at the touch of a switch.

    Turns Off Automatically
    Humidity-sensing fans are ideal for anyone who leaves the house before humidity is properly vented. With a fan this quiet, you can't forget to turn it off when the job is done. That saves energy and money.

    Additional Fans Available
    This fan comes with a 42-watt fluorescent light and features a 4-watt night light (bulb sold separately), as well. The Humidity-Sensing Fan is also available without the lights. A Motion-Sensing Fan is also available. Can't decide? Try the Motion/Humidity-Sensing Fan. For maximum ventilation, install up to 10 Broan SmartSense Fans: These devices communicate throughout your house using INSTEON technology.
