Best Bathroom Exhaust Fans Buying Guide

A bathroom exhaust fan is essential if you want to keep the molds and mildew out of your bathroom or any enclosed space. There are several brands and models of exhaust fans in the market today, so it can be confusing if you are shopping for one. When choosing what’s best for your bathroom, consider the following features.

Airflow Capacity

Airflow capacity aka CFM (cubic feet per minute) refers to the amount of air a fan can circulate. The bigger the CFM value, the faster the rate of air circulation.

However, consider the size of your bathroom and the moisture level before you pick a product. Exhaust fans best for most bathrooms have an airflow capacity ranging from 80 to 210 CFM. The larger your bathroom, the bigger the capacity you should pick.

Here is a good rule of thumb; 1 CFM = 1ft2. So basically, small bathrooms require 50 CFM fans and average size bathrooms need a unit with 100 CFM. For large bathrooms with over 100 ft2, you would need to add together 50 CFM for a toilet, 50 for a bathtub, 50 for a shower, and 100 CFM for a Jacuzzi.

So basically, if your shower has a toilet and Jacuzzi, that would need a kit with a minimum of 150 CFM. If you have a toilet, shower, bathtub, and Jacuzzi, then your fun should have a minimum of 250 CFM.

Note: A fan can have a bigger CFM and operate at a lower value because of the static resistance created by the duct diameter, length, and the number of elbows (bends). So when in doubt, go for a kit with a slightly bigger CFM.

Noise Level

Another factor to consider is the noise level. You would not be comfortable if your bathroom fan is too noisy. Most bathroom fans have noise ranges that are below 1.0 sones. The ideal range for a quiet bathroom would be between 0.3 to 2.0 sones.

Now, here is something no one is talking about; two different bathroom models with the same sone values doesn’t necessarily mean they produce the same sound. A good example is Delta Breez 80 CFM (0.8 sones) and Panasonic 100 CFM (0.8 sones). So even though the latter model has many revolutions that might make it noisy, it is silent compared to the former.

This bathroom fan sounds video can help you realize why Panasonic is the gold standard when it comes to the best bathroom exhaust fans. And this is exactly why we have covered quite a lot of them.

Power Saving Bulbs and Night Lights

When you want to use the bathroom in the middle of the night, the last thing you want to do is turn on the light. A night light, therefore, is essential. However, choose bulbs that save energy. You don’t want to increase your electric bill just because you installed a new bathroom fan. Most of the regular wattage for the bulb lies within 18 to 20W.


Not all bathroom fans have a heating function. It can be handy if you are living in a cold country or if you have an older house that doesn’t have heated bathrooms. It can mean the difference between a cozy bathroom experience and a miserable one.

Color and Design

Everyone loves a bit of class and style, so when choosing a bathroom fan, you should choose one with a color and style that blends with your bathroom design and decor. You don’t want your fan to be the odd one out. While selecting a style, make sure it’s quality too.

Cross Ventilation

The whole idea of going for the best exhaust fan for the bathroom is to keep it adequately ventilated and free of moisture. So you should get yourself products that will allow for proper cross ventilation. Some fans have dampers that keep the cold air out, whereas others have a system that opens up to the outside, letting air circulate inside.

Advanced features

We are living in a world where everything is smart. Therefore, an ideal bathroom exhaust fan should come with a humidity sensor that turns the fan into action on its own. A motion sensor that switches on the lights or the fan itself can save you the hassle of reaching for the wall switches.

These are the features that collectively help you in choosing the best exhaust fans for your bathroom. Take everything into consideration and see if the fan you are looking at will be a good fit for your bathroom.

Frequently Asked Questions (FAQs)

Q. How long should your bathroom exhaust fan be left to run?

A. HVI recommends that 20 minutes is the time required for the fan to clear all the humid air and to ensure that water droplets do not form on the surface of the fan.

Q. What airflow capacity do you need for your bathroom?

A. Airflow capacity is measured in CFM. Ventilation rates of 8 air cycles per hour are usually recommended. To ensure that you have the ideal fan for your bathroom, you have to take the dimensions of the room and multiply. For instance, a 10’’ by 7’’ room will require a 70 CFM fan.

Q. Can an exhaust fan be placed over a shower?

A. Yes, as long as it is a UL-listed fan with a GFCI circuit that allows it to be installed over the shower or the bathtub.
