How To Choose The Best Bathroom Exhaust Fan With Humidity Sensor

Choosing the right humidity sensing bathroom exhaust fan can be a difficult task. With so many different styles and features, it’s hard to know what will work best for you and your home.

But don’t worry, we’re here to help!

We’ve created this helpful guide on how to choose the best bathroom exhaust fan with a humidity sensor and light sensor. We’ll walk you through everything you need to know, such as which features are most important.

So whether you’re in need of a new bath exhaust fan or just looking for some pointers, read on below to find out more!

Airflow Specification

The CFM rating of the unit will determine how quickly it removes moisture, humidity, and odors from the bathroom.

Also, choose the CFM rating based on the bathroom size. For example, a larger bathroom might require more ventilation than a smaller one. This is because the air inside the room has more space to move around and will therefore flow more slowly.

It’s good that most manufacturers indicate the airflow rating and the corresponding room size.

But what do you do if the manufacturer doesn’t specify it?

Well, the rule of thumb applies in this case. It states that you need at least 1 CFM per square foot.

For instance, a bathroom exhaust fan with 150 CFM means it can service a bathroom with a floor size of up to 150 Square feet.

Noise Level

Consider the noise level, too, since this can impact functionality and comfort levels for the users.

So, how much noise should you consider?

Well, we recommend a bathroom exhaust fan that produces 2 Sones or less. That’s about 37 decibels, more like the sound of a refrigerator.

Always, the lower the noise, the better it is for residential use.

Automatic Humidity Sensors

Choose an exhaust fan that has an automatic humidistat. It allows the fan to operate automatically. Moreover, it ensures that the fan isn’t left on continuously.

Energy Efficiency

The most important consideration is how much power the fan needs.

The best bathroom exhaust fan is one that provides the right amount of airflow for your bathroom’s size without drawing too much power.

Where possible, choose an Energy-Star product. It will help you save up to 70% on electricity bills than your typical bathroom exhaust fan.


Safety is a great concern, especially in the wet bathroom environment.

So, choose a product that gives you peace of mind. Notably, consider UL-listed bathroom exhaust fans that are safe to use on bathtubs and shower enclosures. This will help you avoid the risk of electrocution.

Installation Type

How do you want to install your exhaust fan? Is it on the ceiling or the wall? So, consider the mounting type before you buy.

Also, the duct size will determine how well it will work with your bathroom design. The most common duct size for bathroom exhaust fans is 4-inch and 6-inch.

Moreover, consider an exhaust fan that comes with mounting hardware, so you don’t have to purchase separately.

Additional Features

If you can pay more, then we recommend choosing an exhaust fan with additional features. These include motion sensors and LED lights.

Luckily, this article includes the best bathroom exhaust fan with a light and humidity sensor. Plus, there are those with motion sensors. So, you can choose what suits you best.


What is a humidity sensor?

A humidity sensor measures and tracks moisture levels in your bathroom. If it detects high humidity, it will activate a fan to circulate more air throughout the space.

Is a bathroom fan with a humidity sensor worth it?

It’s worth it where the humidity level is always high, and ventilation is required all the time.

What should the humidity level be in a bathroom?

According to the Environmental Protection Agency (EPA), the relative humidity level should be between 30-50% for optimal comfort, health, and safety.

Should I run my humidity sensing exhaust fan during or after showering?

You should run it during your shower and for at least 15-20 after taking your shower.


I hope that this article covers all the information you need to be informed about before making your purchase!

We’ve already reviewed our top picks for the best bathroom exhaust fan with humidity sensor. So, ensure to use our buying guide to choose one that suits your space, personal needs, and budget.
