When you get into the bathroom, does your nose get puckered? Do you sense a faint smell of sewage or a bad odor coming from somewhere? You probably take the room freshener or deodorant and spray it all over. After sometime, when you again enter there, the smell doesn’t go. You decide on cleaning the bathroom but again the smell lingers.

Installing a Bathroom Exhaust Fan would have helped you draw out the odor and wouldn’t have allowed the formation of that nasty odor in the first place.

Is buying a Bathroom Exhaust Fan with Humidity Sensor Really Necessary?

Most people think that the main purpose of installing a bathroom exhaust fan is to remove the odor. However, it is to eliminate the humidity that is generated from the hot tubs. This humidity gives birth to fungal diseases, encourages the growth of molds and makes the metal taps and fixtures rusty.

A bathroom without an exhaust fan becomes home to a lot of contaminations. Also, it damages walls. That is why keeping a check on humidity is important. Humidity sensor in a top bathroom exhaust fan measures and reports air temperature as well as moisture.

Though this does not mandate the use of a quality bathroom exhaust fan but it definitely gives a strong reason to use one. Those who don’t use it struggle for proper ventilation through the bathroom. Opening windows or doors has proved to be inefficient. Go for a best bathroom exhaust fan with the humidity sensor. 

Things to Consider before Buying a Best Bathroom Exhaust Fan with Humidity Sensor

i. Size of the Bathroom Exhaust Fan

If you are looking for a ventilation device that is just right for clearing up all the locked air out of your bathroom, get the bathroom fan of the right size.  The most important factor for choosing the right sized bathroom fan is CFM (Cubic Foot per Minute). It informs us about the amount of cubic foot of air that has moved per minute. The bathroom fans are rated by the amount of air they are capable of moving.

The less powerful will be the fan, the less will be CFM. The more powerful will be the fan, the more will be CFM. Small fans are ideal for small bathrooms whereas the big ones are ideal for large bathrooms.

ii. Noise Level

Noises can be really irksome while taking a peaceful bath. The sound of bathroom fans is measured in sones. The more the sone, the noisier will be the bathroom fan. So it is important to take note of the sound level of the bathroom fan as a noisy one can create sounds as loud as a jet.

One sone can create the sound of a regular working refrigerator. Two sones will have double the sound. One should consider getting a bathroom fan rated below or two as above that will create more white sound.

iii. Additional Features

Humidity Sensor

With people and phones becoming smart, bathroom fans have also become smart. Humidity sensor in a bathroom fan is turned on when the humidity levels rise up and are ultimately turned off when the level reduces.


Some of the bathroom fans come with an integrated feature of lightning. These may offer daytime lightning or the night time lightning or both. This feature makes some models of bathroom fans different from others.


Heaters help to maintain the warmth in the bathroom while at the same time eliminating the moisture. So you can turn it on if you feel cold.

How does a Bathroom Exhaust fan Work?

Most of you might have a bathroom fan at home or if not then you must be thinking of installing it. But ever wondered how does it work? Well, it is not much technical. Most of the ceiling bathroom fans work on the principle of suction. These bathroom fans draw the warm air, moisture, bad odor, and other air-borne germs out of the bathroom through the vent. This moisture passes out of your bathroom via a tube. In a way, it doesn’t work on technicality but simplicity.

Now, what makes a model different than the other is the power of its suction and how fast it can do its work. Also, what extra does it provide you apart from an odor-free bathroom?

How to clean a bathroom exhaust fan?

i. Before doing anything, just turn off the power button of the bathroom fans so you don’t get electrocuted while cleaning.

ii. Remove the cover by unscrewing it or by pressing the prongs to remove it. Dust may fall in this process so be careful.

iii. Unscrew the hold of the fan and carefully remove the fan. Now clear off the dust with the help of a vacuum.

iv. Then dip a microfiber cloth in soapy water and thoroughly clean the cover and the fan. Be careful while cleaning the wings of the fan. You can also leave the cover soaked in soapy water but not for the fan.
