Best Bathroom Fans – 2022 Buyer’s Guide

| Last Updated: May 6, 2022

Ventilation is absolutely integral when you consider a bathroom. Badly ventilated bathrooms are the perfect habitat for mold to grow and fester. Terrible for your health, the mold is the result of poorly circulated humid air that cools after we shower and bath. Having a high-quality bathroom fan can prevent this by circulating and exchanging the air in your bathroom. This prevents the humidity settling and keeps the room fresh.

But how do you choose? Take a look over this guide to understand where to get started when deciding for a bathroom fan.

What are the Available Options of Bathroom Fans?

There are four main types of bathroom fans available on the market. Depending on your needs and space, you can choose between in line, ceiling-mounted, wall-mounted, or combination fans.

In line Fans

Known for their quieter performance, in line fans are mounted between the ducting. Not mounted on to a wall, they are more space-saving than ceiling fans.

Ceiling-mounted Fans

Mounted directly into the ceiling, these fans are a popular choice among consumers. Most expel air out the roof, while some connect to the ducting and expel air out through an external vent.

Wall-Mounted Fans

This fan is designed to be mounted on to an outside wall. Air is expelled directly out through the wall, neutralizing the need for ductwork. These fans are popular due to their simple installation.

Combination Fans

Combination fans have many HVAC features. They can come with functions for heating and lighting, as well as different air extraction techniques. You’ll find a variety of aesthetics to suit your home decor.

Choosing the Best Bathroom Fans

In the search for a bathroom fan, understanding what you’re looking for will make the quest a whole lot easier. Here are a few details to keep an eye out for.

Sound Levels

Imagine trying to relax in a steamy lavender bubble bath, with a constant whirring buzzing through your brain. The sound level matters so try to look out for sones. While many people think they need to look for decibel levels, sones are the subjective measurement used to categorize sound level. The average very quiet fan is around 0.3 sones, while a loud fan is around 4.0 sones.

The Capacity

You need to make sure that your fan can cope with the bathroom’s ventilation needs. If the room isn’t well ventilated, you may end up with damp and mold. While quieter fans can give you a more relaxing experience, they may not be able to handle the amount of ventilation needed for your bathroom.

The power of a bathroom fan is measured in cubic feet per minute (cfm). This shows how much of the air will be pulled out of the room by the exhaust in every given minute. Any room, no matter how small, needs at least 50 cfm to cope with its ventilation needs. Above that, you need to add 1 cfm per square foot of area.

Consider a 5 x 5-foot bathroom is 25 square feet of area. 25 cfm plus an extra 50 cfm means the room needs a 75 cfm bathroom fan.


You need to think about where you want to put it and the restrictions you may have. This will help you understand the type of bathroom fan to choose. If you have an external wall, a wall-mounted fan will mean you don’t need as much ductwork installation. Equally, limited space may suggest you can’t have a ceiling fan.


Many people choose to opt for models with lighting combined with design. The fan automatically activates as the light is switched on. It is a good option to keep the room highly ventilated, but can sometimes use more power than is needed, as you cannot use the fan without the light.

Energy Efficiency

Energy efficient fans not only help the planet, but they also save energy cutting back on utility bills. Look for the Energy Star seal as this showcases the fans that can save as much as 70% on energy usage. Taking into account sound emission, energy consumption, power, and performance, the seal represents one of the most efficient models on the market.


Your thoughts about cost need to cover not only the upfront price but also the running costs of the fan. Energy efficient models with the Energy Star seal may be more expensive, to begin with. But you’ll find that you save a great deal of money on your bills as they use less power.

Benefits of Installing Bathroom Fans

Bathroom fans help to provide ventilation in the bathroom by circulating the air. When we take baths and showers, the warm air can cling to the room. If windows and doors are shut, the air has nowhere to move. The water vapor condenses as the air cools, forming water droplets on the walls, surfaces, and fabrics in the bathroom.

These damp conditions are the ideal environment for mold to develop. Mold that forms in bathrooms is often bad for your health – black mold in particular. These types of mold cause respiratory problems and can have very negative effects on your bones. Molds in bathrooms can also cause and spread fungal infections such as Athlete’s Foot.

Installing a bathroom fan helps to push and pull the air through the room. By sucking the air out of the bathroom, it creates a vacuum for new fresh air to exchange back into the room. This circulating action prevents water from settling, dramatically reducing the likelihood of mold.
