Get ventilation sensitive – using a humidity sensor with your exhaust fan

Thinking about how to improve your bathroom might not be something you spend a lot of time dwelling on and if you do it is probably how you want to replace the vanity, that new shower head or even how you are going to completely remodel. Even when you clean the bathroom, probably more thought goes into what a hassle it is and how much mildew is building up after just cleaning it. While a complete remodel of the bathroom might be out of reach, there is a fairly simple upgrade you can make to your bathroom that will at least help with the cleaning process – adding a humidity sensor to your exhaust fan.

A humidity sensor will automatically turn the exhaust fan on when the humidity level of the room reaches a preset point and will stay on until it falls below that point. Here is how it works; you start the shower, which instantly raises the humidity level of the room so the fan turns on. After your shower, there will still be residual humidity in the room, so the fan will continue to run until that humid air has been exhausted out of the home. This helps prevent the build up of mold and mildew, both like warm humid environments. As an added bonus, it is all automated, nothing for you to do.

Adding a humidity sensor can be done fairly easily. If you need to install a new fan or replace an existing one, there are many options that have a built in humidity sensor (see Air King’s line of humidity sensing exhaust fans). If replacing the fan is not something you need to do, humidity sensing wall switches are available like the Air King DH55. These simply replace the current switch the fan is wired to.
