1. Best Bathroom Fan with Humidity Sensor

This bathroom exhaust fan will auto-adjust to optimize airflow for a bathroom between 50 and 110 square feet. Although the sound level will typically increase as airflow increases with any bathroom fan, you can expect this fan to be very quiet at all airflows.

What’s great is that it is built to help reduce the problem of bathroom mold. With an automatic sensor for both motion and humidity, you can be sure the fan will go on and off when you need it most. (You can choose the best humidity level to trigger the sensor.)

This fan is ENERGY STAR rated, so it meets the US Environmental Protection Agency’s strictest standards for the most energy-efficient products on the market.

2. Best Bathroom Fan with Warranty

The Kaze Bathroom ventilation fan is one of the quietest bathroom fans on the market, with a full 3-year warranty offered by the manufacturer. Super quiet with a sound level of less than 0.5 sones, this powerful fan is suitable for a bathroom of 150 sq ft (13.9 sq meters).

Sliding hanger bars are supplied to position the rust-proof fan housing, but you might need access to the attic to resize the existing ceiling opening. 3 mounting options are available, allowing for easy installation.

The condenser motor on this unit is designed to operate at lower temperatures than other motors, increasing the life span of the bearings and the motor.

3. Best Bathroom Exhaust Fan with Night Light

LED lights are the most energy-efficient way to light a bathroom and you don’t need to worry about the bulbs going out, as most will last 50,000 hours. This fan has a dimmable LED white light for day. You can choose the amber or blue light for the evening. All lights can be programmed with a motion sensor.

This bathroom exhaust fan is a great addition to any smart bathroom! Not only does it have a humidity sensor, but it also comes with an LED-lit touchpad for manual control.

This fan will automatically turn on when bathroom humidity reaches 60% and off when it falls below that. With 80 CFM, this bathroom ventilation is ideal for an average-sized (5;’ x 7′ or 8′ x 10′) bathroom. At 1.5 sone, it’s pretty quiet – expect the same background hum you’d hear from a refrigerator, hardly noticeable.

4. Quietest Bathroom Exhaust Fan

This fan comes in a variety of sizes. The 80 CFM version (optimal for an 8′ x 10′ bathroom or smaller) runs at only 0.3 sones. That’s as quiet as you can get. It’s so quiet, in fact, that the fan comes with a tiny LED light inside the grill that goes on to let you know the fan is actually running.

With the versions of this same fan that are designed for larger bathrooms, as the rate of airflow increases, you’ll get a slightly higher sones rating but they are still very quiet relative to other bathroom exhaust fans for the same sized space.

The other great thing about this fan is that is incredibly energy efficient. Not only is it ENERGY STAR certified by the EPA, but it goes well beyond the requirements for this certification. In fact, relative to a standard bathroom exhaust fan, it can be 75% more efficient. This means it’s good for the environment and good for your pocketbook.

The DeltaBreez Signature fan also has a humidity sensor. When the moisture level reaches 60%, the fan will automatically turn on and run until the moisture level falls below that amount. So you’ll never need to worry about turning it on and off before or after a shower, and you won’t have to worry about bathroom mold. This smart fan knows what to do.

5. Best Sensonic Bluetooth Exhaust Fan

The ultra-quiet ChromaComfort bathroom exhaust fan is equipped with the latest Damper Technology to reduce air leakage by up to 50%. It operates at 110 CFM, controlling the air quality in a space of up to 105 sq ft (9.75 sq meters).

This bathroom fan is designed to do much more than control the environment – its best features include a 24 LED light and a Bluetooth speaker, all controlled by an App on your smartphone or with a wireless wall control.

Customize your tub time to your requirements by changing themes and enjoying your music in the comfort of your bathroom without worrying about loud background noises!

6. Most Economical Bathroom Exhaust Fan

Looking for a bathroom exhaust fan to turn over the air and help prevent mold and mildew without breaking the bank? Enter this Amazon Basics fan designed for spaces 70 square feet or smaller.

The grill is 9.5 x 9.5 inches, and at 2.0 sones, it’s not the absolute quietest bathroom fan on the market but it’s not the loudest either. You can expect it to sound like a loudly humming refrigerator.

While you won’t get any bells and whistles – no motion or humidty sensors, no bluetooth or LED light – you will get an excellent fan at great value.

7. Best Bathroom Exhaust Fan for Small Bathrooms

This little powerhouse will suck up the moisture from a bathroom that is 50 square feet or smaller, moving lots of air in the process. It includes TrueSeal Damper Technology to reduce warm and cold air drafts, helping you create a truly fog-free and comfortable space. 

One of the best aspects of this fan is that you won’t need any attic access to install it. This means you can probably do it yourself.

This fan is also ENERGY STAR rated, so you can feel good about running it. At 0.5 sones, it’s one of the quietest bathroom exhaust fans you’ll find.

8. Best Energy-Saving Bathroom Fan

9. Best for Large Bathrooms

This exhaust fan is perfect for large bathrooms up to 150 square feet. If you’ve got a large space and really want to move the air for ventilation, this is the one.

Fans always get louder as you increase their airflow capacity, and this one is no exception. But for the square footage, you’ll be hard-pressed to find one that’s quieter.

It comes with 2 18-watt fluorescent bulbs for soft white light, but you can also attach a 4-watt night light (bulb not included).

How loud is your bathroom exhaust fan?

 

Sones is a measurement of how quiet or loud your bathroom fan will be. Bathroom exhaust fans typically range from 0.3 to 6.0 sones. As you increase the airflow capacity to ventilate a larger space, the sones of the fan will typically increase.

A fan that is rated 2.0 sones is twice as loud as a fan that is 1.0 sones. There are other factors that affect how loud your bathroom exhaust fan will sound, including the venting and nails or screws. A larger vent without angles will provide quieter ventilation. Fans that are attached with screws instead of nails are also quieter.

Sones	Sounds Like
0.3	Rustling leaves
0.5	Whisper
1.0	Hum of a quiet fridge
2.0	Hum of a loud fridge
3.0	Office noise

What is CFM?

CFM stands for Cubic Foot Per Minute. CFM gives you an idea of the rate of airflow that passes through your fan unit. A larger bathroom will require a higher CFM rating. 

You want to make sure you get a bathroom fan this is strong enough to ventilate your space but not so big that it will blow you over and make standing in your small bathroom feel like you’re in a windstorm.

A rough guide is that your CFM should, at minimum, equal the square footage of your bathroom. You can get a good estimate of this by measuring the length and breadth of your bathroom and multiplying the figures. 

 

What is a smart bathroom exhaust fan?

A smart bathroom fan is one that has sensors for detecting humidity and motion. It will automatically turn on when the humidity drops below a certain level or when someone walks into the bathroom. These fans often have additional bells and whistles, such as LED lights, a night light, or Bluetooth speakers.

There are several smart fans listed above. The Panasonic WhisperSense Bathroom Exhaust Fan is an example of a smart bathroom fan.
