5 Best Bathroom Exhaust Fan With Humidity Sensor (With Bluetooth)

Sharing is caring!

A bathroom exhaust fan with humidity sensor. It is basically a fan that automatically turns on once it senses enough moisture in the room.

Benefits to you: Why should you buy an exhaust fan with a humidity sensor? There are many reasons that you should.

Humidity is made when water vapor in the air comes in contact with cool surfaces like windows and walls. This makes your home hotter and decreases energy efficiency (makes it cost more to heat/cool your house).

Best Bathroom Exhaust Fan With Humidity Sensor

The moisture also builds upon mirrors, which you cannot see unless you look for them because they are not shiny or reflective, but this is the time you should know that you are breathing in very high amounts of humidity.

You do not want to breathe in that much humidity. Why? Because it can cause health problems like lung diseases, infections, and breathing issues.

What’s wrong with having a fan? The fan helps get rid of moisture by pulling air out of the bathroom which decreases humidity and lowers the risk of health issues.

But, what if you forget to turn off the fan after you are done showering?

This is where this product comes into play:

As long as it senses moisture in the room (after you use the bathroom), then that means there is a high level of humidity in the room. Once it senses this, then the fan will automatically turn on so you do not have to worry about forgetting to turn it back on when you are done taking a shower or bath.

Benefits Of Installing A Humidity Sensor Exhaust Fan

There are many benefits to a humidity sensor exhaust fan. Let me tell you about all the benefits that you’ll get before you decide to purchase one.

Protect your bathroom from damage

It protects your bathroom. Bathrooms can be damaged by excessive moisture.

A humidity sensor exhaust fan removes excess moisture and humidity, creating the ideal environment for your bathroom.

Saves damage repair costs

It can be costly to fix humidity problems in bathrooms. A humidity sensor bath fan can help prevent damage.

This means that you won’t need to spend money on repairs. The fan’s sensor ensures that the humidity levels are safe.

Prevents the growth and spread of mildew and mold

Prevents the growth and spread of mildew and mold

You can prevent mold growth in your bathroom by installing a bath fan with humidity sensors.

You already know that molds thrive in moist conditions, so a bathroom is a perfect place to grow them.

A humidity-sensing bath fan will keep your bathroom safe from mildew and mold growth.

Automatic shutoff feature

A bathroom exhaust fan equipped with a humidity sensor has another advantage: it will automatically turn off when humidity levels drop below a set level.

This feature prevents accidents from happening if a fan is left on for too long.

If a fan is left on for too long, it can heat up and cause a fire. This problem is solved by the humidity sensor on this bath fan.

The fan is activated by the sensor according to the set limit and the prevailing humidity levels.

No need to perform manual operations

It is easy to use a bath fan that has a humidity sensor. The humidity sensor can automatically turn it on or off when it senses the level of humidity.

Humidity Sensing Bathroom Fan Switch

It is crucial to maintain the correct humidity level in your bathroom. A humidity-sensing bathroom fan can be a great option if you have high humidity levels.

Mold and mildew can grow in high humidity levels, which could pose a health risk. It can also cause damage to the bathroom’s walls and aesthetics.

Humidity Sensing Bathroom Fan Switch

A bathroom exhaust fan is a great option in this situation. However, it can increase your electric bill if you use it constantly. What should you do?

This problem can be solved by a humidity-sensing bathroom fan.

Bathroom humidity sensor switches come with an integrated sensor. It measures the moisture level in the air and can be detected.

These switches are made for home use.

The sensor switch features a sensitive microprocessor that can sense humidity and a humidity sensing technology. It can continuously measure humidity.

It switches on the bath fan automatically when it senses humid air. A humidity sensor can be either built into the fan itself or installed in your wall switch.

Can a bathroom fan and light be on the same switch?

You may find it necessary to wire both a light and a bathroom fan on one switch. This isn’t a bad idea, and I will explain why.

You must turn on the lights whenever you use the bathroom. The exhaust fan can be used to reduce moisture levels and prevent mold and mildew growth in your bathroom.

Hot water condensation can decrease the life expectancy for light bulbs and light fixtures.

The humidity sensor will prevent water from condensing by turning on the bathroom exhaust fan. Instead, the fan will draw out the vapor.

It can be advantageous to have the fan and lights on the same switch. This can solve your problems and give you beautiful bathroom space.

How to wire bathroom fan with humidity sensor?

Many people want to know how humidity sensors work in bathroom fans. Let’s get into it in this section.

A bath fan equipped with a humidity sensor usually has six wires. These include 2 black, 2 white, and 1 brown. The brown wire is used for speed control or humidity sensors.

You can switch the fan and humidity sensor independently for a variety of operating modes.

The humidity sensor can be turned on to control the fan’s speed, but the fan itself will override that setting by turning it on.

The fan and humidity control can also be controlled separately. Wall control with 1- or 2-functions should be used. Avoid using a dimming switch for humidity control.

The brown wire can be connected to a switch. You can also connect the brown wire directly to the hot conductor for the full functionality of the humidity sensor.

When you turn on the fan, make sure both the brown and black wires are connected to a power source. It should now be easy to wire a bathroom fan with a humidity sensor.

If you want to learn how to wire a humidistat to your fan, connect a permanent neutral, live, and earth.

You should make sure the switched feed is connected with a separate pull switch located above the WC. This will allow you to turn on the fan separately.

Choosing The Right CFM Exhaust Fan Size

Bathroom exhaust fans are rated according to the amount of air they can move, in case you didn’t know.

CFM is a measure of cubic feet per minute. This is an important factor to consider when purchasing a CFM exhaust fan in your bathroom.

Bathrooms with 100 square feet or less are compatible with standard exhaust fans. At least 1 CFM is required per square foot. Multiply the length by the width to determine how many square feet your bathroom covers.

Let’s take, for example, a bathroom that measures 7 feet by 8 feet in width and length. 56 square feet equals 56. You will need a fan that has at least 54 CFM. There are many other factors that can also be important.

It is always a good idea for the bathroom vent fan to be slightly larger than it actually is. For example, a 56-square-foot fan might be better than a 60 CFM fan to achieve better results. You might also need to consider whether you have separate rooms or a tub with a jetted bathtub in your bathroom.

CFM fans must be at least 50 CFM. If your bathroom measures only 42 sq. feet, then you’ll need a 50 CFM exhaust fan.

Bathroom Dehumidifier VS Exhaust Fan

Are you finding your bathroom’s air too dry? Are you experiencing excess moisture in the bathroom? You have two options if you do. A dehumidifier and an exhaust fan. How do you decide which one is best?

To make it easier for you, I have created a quick comparison between the bathroom dehumidifier and the exhaust fan.

  • The dehumidifier can be a practical option because it reduces humidity levels. It removes moisture from the air and then releases it as dry, fresh air. A bathroom dehumidifier is also more durable.
  • An exhaust fan circulates air through the bathroom, improving ventilation. It does not maintain humidity levels. The main difference is in the operation. Each appliance uses a different mechanism.
Bathroom Dehumidifier VS Exhaust Fan

Many people want to know if a bathroom dehumidifier is possible to replace the exhaust fan. The short answer to your question is yes. If the exhaust fan does not provide enough humidity control, you can replace it with a humidifier.

These are some appliances you can use in your bathroom to lower humidity levels:

It should be easy to choose which bathroom dehumidifier to buy after this comparison of the exhaust fan.

A dehumidifier is a great choice if you have constant moisture in your bathroom. An exhaust fan is a better choice if humidity is only sporadic.

Bathroom Fan with Humidity Sensor Buying Guide

There are many factors to consider when choosing a bathroom fan equipped with a humidity sensor.

CFM

This refers to the airflow rate of the exhaust fan. It can be used to help determine the size of your bathroom.

Humidity sensors

This range includes bathroom exhaust fans that are fitted with a humidity sensing device. This sensor is used to measure humidity levels in the room and then automatically starts or stops the fan. Most humidity sensors have the temperatures set up to turn on or off the fan. But, you can program the humidity settings by using a switch.

The timer

Lets the fan run for an additional time after the humidity sensor is turned off. This ensures your bathroom is properly ventilated to prevent moisture and mold growth.

Noise levels 

It is important to take this into consideration when choosing the best bathroom fan with a humidity sensor. After all, you don’t want the sound of an AC conditioner in your shower. It is measured in sones. The lower the number, you will hear less from the bathroom fan.

Warranty

A warranty against manufacturing defects guarantees that your bathroom fan will work for years. Buy from a well-respected brand, or read bathroom fan reviews before purchasing.

Energy Use:

Energy use refers to the amount of energy used by a bathroom exhaust system fan. Energy Star certification will ensure that your monthly energy bills are not increased.

Efficiency:

This indicates that the fan can be both efficient and powerful. Installing a humidity sensing bathroom ceiling fan can help you to save money on your energy bills. They don’t use much energy and are great for bathrooms.

CFM stands for Cubic Feet of Air per Minute. It is used to measure bathroom fan efficiency. It measures the total volume in cubic feet of air for every minute it moves.

A bathroom fan’s speed is an indication of how much air it can move per minute. This determines the efficiency of your bathroom fan. You will need a fan with a higher CFM for a larger bath and vice versa.

Sensor adjustments

A bathroom exhaust fan that has a humidity sensor works better when there is more humidity. It not only saves energy but also improves bathroom exhaust fan efficiency.

A sensor monitors humidity levels in your bathroom and activates the fan if it exceeds a specified level. It will shut off if there is too much moisture.

Look for a model which allows you to adjust your sensors. This will allow setting the desired moisture level at which your fan should turn on.

Bathroom Size

The size of your bathroom will dictate the size of the bathroom exhaust fan you choose. This is straightforward logic.

A larger bathroom will mean a larger bath fan. The fan should be large and powerful enough that it covers the bathroom’s entire surface. It is therefore important to decide the bathroom size.

Fan size:

Also, be sure to think about the size of the fan. You don’t want to buy anything that is too small or too big. The best thing is to get a fan that fits in your bathroom.

Bath fans with smaller CFMs have lower performance, while larger fans have higher CFMs. Selecting the right size fan is important for your bathroom.

It should be able to allow proper ventilation to your shower.
