All bathroom fans make some amount of noise. But some are louder than others. When buying a humidity sensing bathroom fan make sure you check the noise levels.
You should choose a less noisy model, so it doesn’t interfere with your peace while showering. Modern bath fans are made for silent operation.
They are so quiet that you will hardly know it is on.
Energy use refers to the amount of energy consumed by a bathroom exhaust fan. If you don’t want to spike up your monthly energy bills, then you should opt for a model that is certified by Energy Star.
This indicates that the fan is energy-efficient and yet intelligent and powerful. Installing an energy-efficient humidity sensing bathroom fan can help you save a lot of money on energy bills. They consume very little energy and are perfect for a bathroom setting.
The efficiency of a bathroom fan is measured in terms of CFM or Cubic Feet per Minute. It measures the total volume of air in cubic feet for each minute it moves.
In the case of a bathroom fan, it indicates the amount of air it can move in a minute. This determines how well your bathroom fan will perform. For a bigger bathroom, you will need a fan with higher CFM and vice versa.
Humidity improves the overall efficiency of a bathroom exhaust fan with humidity sensor. Not just that, but it also helps conserve energy.
A sensor monitors the moisture levels in your bathroom and activates the fan whenever the humidity level rises above a certain level. It turns off when the moisture level is low.
You should go for a model that allows you to adjust the sensors. This will let you set the moisture level at which the fan should turn on.
You need to buy the best bathroom exhaust fan with humidity sensor based on the size of your bathroom. This is simple logic.
If you have a bigger bathroom, you will need a bigger bath fan and vice versa. The fan should be big and efficient enough to cover the total area of your bathroom. Therefore, determining the bathroom size is very important.
Lastly, you also need to consider the size of the fan. You shouldn’t buy anything too big or too small. The best is to buy a fan size that is right for your bathroom size.
Smaller bath fans have lower CFMs, and bigger bath fans have higher CFMs. You need to choose a fan size that is suitable for your bathroom.

Benefits Of Installing A Humidity Sensor Exhaust Fan
A humidity sensor exhaust fan comes with a lot of benefits. Before you set out to buy one, let me shed some light on all the benefits you will get from it.
Protects your bathroom from damages
First of all, it helps protect your bathroom. Excessive moisture levels can damage your bathroom in various ways.
But a humidity sensor exhaust fan helps remove excess moisture and humidity to create the perfect environment in your bathroom.
Saves damage repair costs
Fixing bathroom problems caused by humidity can cost you a lot. But if you have a humidity sensor bath fan, it can prevent damages in the first place.
As a result, you don’t have to spend any money on damage repair. The sensor fitted in the fan ensures that humidity levels in your bathroom are within a safe range.
Prevents the growth of mold and mildew
A bath fan with humidity sensors can also prevent the growth of mold and mildews in your bathroom.
As you already know molds grow in humid conditions and a bathroom is the perfect breeding ground for such a nuisance.
But if you have a humidity sensing bath fan, your bathroom will stay protected from mold and mildew growth.
Automatic shut off feature
Another advantage of a bathroom exhaust fan with humidity sensor is that it automatically shut off when the humidity levels fall below the set limit.
This automatic shutoff feature is highly useful in preventing accidents that are likely to happen when a fan is left running for a long time.
When you leave a fan running for hours, it gets overheated, which can lead to a fire accident. But the humidity sensor in this type of bath fan resolves this problem.
The sensor activates the fan to turn on/off according to the prevailing humidity levels and the set limit.
No manual operation needed
A bath fan with a humidity sensor is convenient to use as you don’t have to turn it on manually. It can turn on and off automatically as soon as it senses humidity levels.
Humidity Sensing Bathroom Fan Switch
Maintaining the right humidity level in your bathroom is very crucial. But if your bathroom has high humidity levels, you can find a humidity sensing bathroom fan switch to be highly useful.
High humidity levels lead to mold and mildew growth, which has potential health risks. Not just that, but it also damages the walls and beauty of your bathroom.
In this case, a bathroom exhaust fan can be of great help. But using it continually can spike up your electric bills. So, what should you do?
A humidity-sensing bathroom fan switch can resolve this problem.
A bathroom humidity sensor switch comes with a built-in sensor within a switch. It can detect and measure the level of moisture in the air.
These types of switches are specially built for home use.
A sensor switch is designed with a very sensitive microprocessor and humidity sensing technology. This helps it to continually measure humidity.
Whenever it detects overly humid air, it automatically switches the bath fan on. You can have a humidity sensor already integrated into a fan or you can get it in your wall switch.
Can a bathroom fan and light be on the same switch?
Many of you may feel the need to wire a bathroom fan and light on the same switch. Well, this is not exactly a bad idea and I will tell you why.
Whenever you use the bathroom, you switch on the lights. While running the exhaust fan helps you to keep the moisture levels low and thus, prevent mold and mildew from growing in your bathroom.
Condensation from hot water can reduce the life expectancy of a light bulb or light fixture.
But if you switch on the bathroom exhaust fan with humidity sensor, the water won’t get the chance to condense as the fan will pull out the vapor.
Running the lights and the fan on the same switch can be beneficial. It can help you solve these issues, so you will have a lovely bathroom space to enjoy.
How to wire bathroom fan with humidity sensor?
Many of you want to know how to wire bathroom fan with humidity sensor? Let’s talk about that in this section.
A bath fan with a humidity sensor typically has six wires: 2 black, 2 white, 1 brown, and ground. The brown wire is for a humidity sensor or speed control.
The humidity sensor and fan can be switched independently to give you a choice of operational modes.
Switching on the humidity sensor gives it control of the fan cycle, but turning on the fan directly overrides that mode.
In other words, the fan and humidity control can be operated separately. You should use a 1- or 2- function wall control. It’s better to avoid using a dimmer switch for humidity control.
You can hook the brown wire to a switch. Alternatively, you can connect it directly to the hot conductor to allow the humidity sensor to function full-time.
Make sure that both the black wires and the brown wire of the fan get a power supply when you turn it on. Now that you know how to wire bathroom fan with humidity sensor, it should be easier for you to get it done.
For those who want to know how do you wire a humidistat to a fan, you should connect a permanent live, neutral, and earth to the fan.
Make sure that the switched feed is connected to a separate pull switch above the WC with an on/off indicator. This will let you switch on the fan independently.
Choosing The Right CFM Exhaust Fan Size
For those who didn’t have an idea, bathroom exhaust fans are rated for the amount of air they can move.
This is measured in CFM or cubic feet per minute. It is an important consideration when buying a CFM exhaust fan for your bathroom.
Standard exhaust fans are suitable for bathrooms that are 100 square feet or less. You need at least 1 CFM per square foot of room area. To determine the total square footage of your bathroom, multiply the length times the width.
For example, let’s say your bathroom is 7 feet wide and 8 feet long, its square footage is 56. This means you need to get a fan with at least 54 CFM. But there are other things as well that matter.
The minimum CFM fan size is 50 CFM. So if your bathroom is just 42 square feet, you will have to buy a 50 CFM exhaust fan.
Bathroom Dehumidifier VS Exhaust Fan
Is the air in your bathroom too muggy? Do you have excess moisture in your bathroom? If yes, then you have two options to choose from: a dehumidifier or an exhaust fan. But how do you figure out which one is the best?
To help you out, I have laid down a brief comparison of bathroom dehumidifier vs exhaust fan.
A dehumidifier is a convenient option as it efficiently reduces humidity levels. It pulls out moisture in the air and releases it back as dry and fresh air, without any water content. Also, a bathroom dehumidifier is more durable.
Many of you want to know if a dehumidifier can replace the exhaust fan in the bathroom. The short answer is yes! If the exhaust fan is not enough to control the humidity levels, then you should replace it with a dehumidifier.
Here are some of the appliances that you can use to reduce humidity levels in your bathroom:
- Exhaust fans
- Air conditioner
After this bathroom dehumidifier vs exhaust fan comparison, it should be easier for you to decide which one to get.
If you have persistent moisture in your bathroom, then a dehumidifier would be a great option. But if you experience humidity for short periods, then an exhaust fan will do.

Bathroom exhaust fans with humidity sensors help remove excess moisture from the air and thus, prevent damage to ceilings and walls.
Plus, it prevents the growth of mold and mildew in your bathroom. Humidity sensing fans are equipped with a sensor that activates the fan when the humidity rises and automatically turns it off after a set period.
Is it bad to oversize a bathroom exhaust fan?
Bathroom exhaust fans are rated in CFM or cubic feet per minute. It measures the amount of air a fan can move per minute.
Therefore, it is always a good idea to oversize the fan slightly. If you have a 54-square-foot bathroom, then you should go for a 60 CFM fan for good measure.
