What is a bathroom vent fan with humidity sensor?
This type of bath fan comes equipped with humidity sensor (an electrical part that responds to the moisture in the air). Its function is similar to how a home thermostat works, except it works based on relative humidity rather than temperature.
The humidity sensor automatically activates the ventilation fan to reduce excess condensation. It runs until the moisture drops below the pre-programmed relative humidity percentage setting.
If you have a family with forgetful occupants, a humidity sensing fan is a great and cost-effective way to eliminate the moisture from your bath space automatically.
Benefits of Using Humidity Sensing Bathroom Fan
The main purpose of using such a device is to eliminate the humidity produced in the bath space. However, there are more benefits to using this stuff.
- Odorless and good-looking bathroom
Moisture makes metal fixtures and taps rusty. It may also damage walls, and even the room foundation could collapse. The humidity sensor of vent fan measures and reports the moisture level. It lets you enjoy a soothing bath without being disgusted by the odors.
- Least Chances of Micro-Organisms Growth
Too much humidity leads to condensation. It encourages the growth of molds, mildew, and these are proven to be one of the leading disease carriers. Skin irritations, allergies, and other serious health problems may occur due to excess humidity. Exhaust fans with sensors automatically control the moisture level and keep your bathroom environment healthy.
- Automatic turn on/ off
Vent fan with humidity sensor controls the humidity level with automatic turn on/off feature. The AUTOMATIC SETTINGS CONTROL of this device reduces your worry about whether it is time to turn the fan on or off.
- Saves the renovation cost
If you compare the cost of an exhaust fan with a humidity sensor and the maintenance charge for restoration of your damaged wall, you’ll find that the difference is huge. In fact, to protect the damaged caused by excess humidity, humidity sensing vent fan is way cheaper than fixing the damages.

Humidity Sensor Bathroom Fan Installation- Do’s and Don’ts
- Install the device away from cooling or heating sources as these may affect the humidity levels.
- If it’s a ceiling-mounted model, locate the unit within or above (GFCI protected circuit required) 5 ft. of the showerhead.
- Install the unit by following the manufacturer’s instructions for proper sensing.
- Avoid installing the unit near the window as it may respond to the outside humidity level.
Humidity Sensor Extractor Fan Cleaning and Maintenance
For efficient and quiet operation, attractive appearance, and long service life, proper cleaning and maintenance of the device is a must.
- To clean the unit first lower and detach the grille. Then vacuum the interior of the unit. You can use the dusting brush attachment to do this.
