What is Humidity Sensing Bathroom Fan and How It Works

The best bathroom exhaust fan with humidity sensor is a device that you mount onto the bathroom’s ceiling. It controls the level of humidity in the air to ensure that it is at its optimal level.

This device makes use of the technology of both an exhaust fan and a humidity sensor. Once this sensor detects an increased humidity level in your bathroom, it signals the fan to turn on to circulate the air inside.

As a result, too much moisture in the walls, as well as every nook and cranny, is reduced or even eliminated. Why do you need to get rid of humidity, anyway?

Benefits

A bathroom exhaust fan adds value to a home, but what does it really do? Are there really benefits to having it installed in your bathroom?

If you’re unsure why you need a humidity-sensing bathroom fan, here are a few of the most common reasons:

Automatic On and Off

Unlike a regular exhaust fan that you switch on and off manually, those equipped with a humidity sensor turns on and off automatically.

As such, you can be sure that your bathroom stays moist-free, even if you live with housemates who forget to turn it on after showering or bathing. This is especially beneficial for households with children and older occupants.

Protects Your Bathroom

Because humidity is kept at a minimum, you’re assured that your bathroom is protected from mold and mildew growth. In turn, everything from the tile and grout to the paint and the walls will last longer. That musty smell from mold growth is also eliminated.

Too much moisture will also cause rust to form and eat away at door and cabinet hardware. Thankfully, installing a fan with a humidity sensor solves these problems and more.

Better Air Quality

If there is no build-up of mold, mildew, and rust, bacteria growth is also kept at bay. Without these contaminants lurking in the air, you will have better air quality in your bathroom.

How to Choose the Best Bathroom Fan for Humidity

Determined to buy a humidity-sensing bathroom exhaust fan? You should learn about which factors to consider so that you’d know which model to choose. For that, we’ve got your back.

Below are the considerations you have to keep in mind when choosing a bathroom fan for humidity:

Bathroom Size

Of course, the first thing you should find out is the size of your bathroom. More often than not, the CFM or the airflow capacity of the fan must be strong enough to accommodate the entirety of your bathroom.

Sensor Adjustments

Next, find out if the unit allows you to adjust the humidity sensor. Some will let you turn it on and off so that you can save on energy, especially when you’d be out of the house for days on end.

Fan Speed and Strength

Aside from sensor adjustments, you might also want the convenience of having the option to adjust fan speed and strength. In this way, you can customize the settings to your specific needs and preferences for a more streamlined experience.

Housing Size

While your bathroom ceiling might already come with a fan, the replacement you buy should be the same size so that you won’t have to make adjustments anymore. Check the product specifications of the unit to see if it would fit the holes in your ceiling.

Noise Levels

With the advancement in the technologies we have today, we can now enjoy bathroom ventilation minus the noise. If this is a feature that’s important to you as it is to us, check the noise level of the unit you’re planning to buy. You might also want to read a few more reviews to make sure it’s as quiet as the brand claims it to be.

Brand

Finally, and speaking of the brand, consider who designed and manufactured the unit. In this way, you will know if you can trust that the product will last for a long time. Also, in knowing the brand, you can check for warranties as well as the efficiency of their after-sales support.

When it comes to bathroom ventilation, the crowd-favorite is undoubtedly Panasonic, though there are also others that offer excellent options.

FAQ

1. Can I choose not to buy an exhaust fan?

If you check building codes in your area, you will find that an exhaust fan is a requirement, especially if your bathroom doesn’t have an operable window. If we’re being honest, we think that every bathroom should have a fan, regardless if it has a window or not.

This device controls the humidity level in the bathroom much better than a window can. Without it, you’re just attracting mold and mildew to grow in your bathroom.

2. What does a high CFM mean?

CFM, or cubic feet per minute, is the measurement used to determine a fan’s ability to circulate air. To lower the level of humidity effectively, the fan’s CFM should be high enough to accommodate the size of the entire room.

For bathrooms, the fan should be strong enough to circulate and replace the air inside at around five to eight times in an hour.

3. What is a good sone rating for a bathroom ventilation fan?

You might have noticed that we measure fan noise in “sones.” If you want bathroom venting that operates quietly, choose one that claims it works at a noise level of 1.0 sones or lower. In comparison, 1.0 sones is the same sound level as a refrigerator, while 4.0 sones is the sound level of a television.

4. Where should it be placed?

In order to maximize the effectiveness of the unit, you should know where to place it best. In a powder room, mount it directly above the toilet. In a bathroom, choose a location that is as close to the tub or shower as possible.

Have a professional electrician install it for you to ensure that it’s properly mounted. He or she would also know the electrical requirements of the unit. If you can, show him or her the unit before placing your order.

5. How long should I leave it on?

The Home Ventilation Institute (HVI) suggests leaving the fan on for roughly 20 minutes after showering. In this way, you can be sure that all moisture has been eliminated, which guarantees little to no mold or mildew growth.

Conclusion

In the end, choosing the best humidity sensing bathroom fan will all boil down to your specific needs and preferences. Lucky for you, the choices we presented above all come from trusted brands, so you can rest assured that your money is well spent.

Hopefully, the buyer’s guide, as well as the FAQ section, helps you in choosing the right exhaust fan for your bathroom.

If you ask us, we’d definitely go for the Panasonic FV-0511VQC1 WhisperSense. This unit is one of the top-rated ventilation fans in the current market, and Panasonic is also the leading brand in this industry.
