I bought two, one with a light switch. Both work extremely well. They come on if I forget to turn the fan on. They stay on for 30 minutes, so there is no need to remember to turn the fan off. And if the humidity is still high, they stay on until the humidity drops.Read MoreRoger K.

Works great!! Set the fan timer to 30 min and walk away. I like it. I did disable the condensation senor because it is very humid where I live and the thing kept turning on. Also I have a shallow wall box so I installed an "extender" to make everything fit and look nice.Read MoreDavid B.

DewStop has taken its patent pending technology and packaged it into a single fan switch anyone can install!
Simply connect your new or existing bathroom exhaust fan to the DewStop switch. When DewStop senses rising condensation levels, it automatically turns on the fan and keeps it on until the condensation is no longer a problem and your room is dry.
You can also turn it on and off manually when you want to, or just rely on the DewStop sensor to do the job.
