Monitor humidity and dew point levels in a room with DewStop, a fan switch that automatically switches the exhaust fan on or off to adjust for condensation. Designed to help minimize damage to walls and household goods, as well as lessen or stop the growth of mold, the switch is triggered when steam becomes too heavy for the air to support and moisture accumulates on surfaces. DewStop will then automatically turn the fan on and keep it on for 30 minutes or until the condensation is no longer a problem and the room is dry. Available in two models, the FS-100 fan switch only or the FS-200 fan and light switch.
