The Best Bathroom Fan Option


There’s the potential for structural and surface-level damage if your bathroom isn’t properly ventilated. Excess humidity causes damage in myriad forms—cracked paint, peeling wallpaper, and warped cabinetry.

Moisture buildup in the bathroom also encourages mold growth in drywall and caulking, threatening indoor air quality. The best bathroom fan removes excess moisture effectively, protecting your bathroom from water damage while helping eliminate mirror fog and odors.

There’s a wide variety of options, from bare-bones models to high-end fans that come with built-in lighting, heaters, and motion sensors. Continue ahead for a guide to navigating the options and some top picks below!

The Best Bathroom Fan Option


Types of Bathroom Fans

Before looking through the options for the best bathroom exhaust fans, it’s important to decide which fan type you’d prefer. Bathroom ventilation fans come in two main types: ceiling fans and in-line fans. Each type offers pros and cons to consider.

Ceiling Fans

As the name implies, ceiling fans are mounted in the ceiling of a bathroom. An air intake vent sits right in the ceiling, with the fan portion directly above it. The fan pulls air from the bathroom up into the vent by creating suction and then releases it through the roof vent on the other side.

Some ceiling fans include lights and can be used to make a bathroom brighter or to replace an existing overhead or vanity light. They are also generally a bit easier to install. However, due to their size and weight, the installation options may be more limited than they are with in-line fans.

Since ceiling fans are located directly above the bathroom, users may notice more noise and vibration than they would from an in-line fan.

In-Line Fans

In-line fans are installed either in the attic above the bathroom or another location a bit away from the bathroom. For these models, users install a vent in the ceiling with ductwork that routes to the exhaust fan.

This setup moves the fan a bit farther from the bathroom ceiling for reduced noise and vibration. It also makes it possible to add multiple ceiling vents and connect them to the same fan to provide additional ventilation to a larger bathroom.

With an in-line fan, you aren’t as constrained by the available space in the ceiling directly above the bathroom. In some cases, this makes it possible to install a larger and more powerful fan than would otherwise fit. However, installing an in-line fan and setting up the ductwork can be more involved than installing a ceiling fan.

What to Consider When Choosing the Best Bathroom Fan

As you’re looking through the best bathroom exhaust fans, there are quite a few features to keep in mind. These include the airflow capacity, energy efficiency, and noise of each model. Beyond technical features, consider ease of installation, versatility, and how it will look in your space.

Airflow Capacity

The best bathroom exhaust fans’ performance is measured in cubic feet per minute (CFM), which gives the amount of air moved by the fan each minute. The product’s box will list the CFM number, and it will typically give a suggested room size as well.

As a general rule of thumb, choose a fan with a minimum CFM rating equal to your bathroom’s square footage. For example, choose a 50-CFM-rated fan for a 50-square-foot bathroom and a 100-CFM-rated fan for a 100-square-foot bathroom.

For even more accuracy, measure your bathroom and use the following mathematical formula:

Length x Width x Height x 0.13 = Suggested CFM

Suppose your bathroom is 8 feet wide, 10 feet long, and 8 feet high. You’d multiply 8 by 10 by 8 by 0.13 for a total of 83.2. In this case, a fan with a CFM rating of 80 would probably be sufficient for your bathroom.

Energy Efficiency

As with purchasing any new appliance or electrical product, consider energy efficiency when shopping for a bathroom fan. Fans that are energy efficient use less energy than other models, meaning that they can help you save on your monthly electric bills while also decreasing your home’s environmental footprint.

Energy Star certifications were developed to help users easily identify energy-saving models. Energy Star–certified ceiling fans use an average of 70 percent less energy than their less-efficient counterparts.

In order to receive Energy Star certification, most bathroom fans must also meet the maximum allowable sound levels and performance levels for airflow.


Many bathroom fans are designed for more than just ventilation. Consider models with these convenient features:

  • Many people opt for a bathroom fan with an integrated light, which can replace an existing light fixture using the same wires, making for easy installation.
  • Night-lights offer a comforting glow to guide late-night bathroom visitors.
  • Some bathroom fans have motion sensors that turn on the light automatically when someone walks into the bathroom.
  • Fans with humidity sensors activate automatically when the moisture levels reach a specific level.
  • For cold days and chilly baths, built-in heaters can warm up the room and ventilate simultaneously.


Visual appeal can also be important when choosing a bathroom fan. Consider the overall style and decor of your bathroom, and choose a fan that will coordinate with the space. One basic item to consider is the fan’s color.

Many bathroom fans are white, but some may include a paintable cover that will allow you to customize the fan’s color to blend in with your ceiling or walls.

Other bathroom fans offer decorative fixtures that can help add to the style of the space. For example, some bathroom fans may feature interchangeable finials or trim in different finishes (such as white, chrome, nickel, or brass), hanging pendant lights, or other intricate or eye-catching designs.


The noise emitted by an exhaust fan is rated in “sones,” and the quietest bathroom exhaust fans have a sones rating between the range of 0.5 to 6.0. The lower the sones number (which is typically printed on the fan box), the quieter the fan will be when operating.

Since a sones rating of 1.0 compares to the sound of a quiet refrigerator, any fan with a sones rating of 1.0 or less is considered among the quietest bathroom exhaust fans. On the other end of the scale, a sones rating greater than 4.0 might be loud enough to drown out your shower singing.

Many manufacturers today produce bathroom fans that operate quietly. If you’re very concerned about sound, consider installing a 6-inch ducting attachment for your fan rather than the standard 4-inch attachment. Air can move easier in a wider duct, so a 6-inch duct puts less strain on the fan and allows for quieter operation.


When you draw moisture-filled air out of the bathroom, it needs somewhere to go. Some bathroom vents release exhaust into a home’s attic; however, this setup isn’t ideal since excess moisture in the attic can lead to mold-related issues. It’s usually best practice to vent bathroom fans to the outdoors.

If the bathroom is located on the first level of a multistory home, you can vent the air through the side of your house. A standard ceiling-mounted fan is suitable for this type of venting, as long as you can run the ducting through the ceiling joists to an exterior wall.

For any bathroom located on the floor directly below the attic, your best bet is to direct the vented air to the attic and then, via ducting, either to a soffit under the roof’s eave or out through a vent pipe in the roof. If you can’t run ducting between the joists, and if your bathroom has at least one exterior wall, you can install a wall-mounted fan that vents the exhaust directly out the side of the house.

When installing a bathroom fan, the best location is typically between the shower and toilet, in an area of the ceiling without any obstructing joists or pipes. Replacement fans should be installed in the same location as the existing fan.

Keep in mind that larger bathrooms may require multiple fans to effectively ventilate the space. Fans with features such as lights, heaters, and night-lights may require additional wires or a designated circuit to operate.

As a bonus, many of the fans are Energy Star certified, meaning they perform more efficiently and offer greater savings compared to typical exhaust fans.


There are many benefits of adding a bathroom fan to your bathroom, but you may still have some questions about choosing the right fan for your space. Refer to the frequently asked questions below to gain more knowledge to help you make the best selection.

Q: What is the difference between a ventilation fan and an exhaust fan?

Ventilation fans and exhaust fans both share the goal of leaving the air in a space cleaner and fresher, but the way they go about reaching this goal is different. Ventilation fans pull cleaner air into spaces from the exterior, while exhaust fans remove pollutants and other contaminants from the air in a space.

Q: What CFM do I need for a bathroom fan?

To determine the CFM (cubic feet per minute) needed for your bathroom, consider the square footage of the space. The CFM should be at least as high as this number, so a 100-square-foot bathroom will require a fan with a rating of at least 100 CFM. For greater precision, use the following formula to make sure you choose the right fan for your bathroom: Length x Width x Height x 0.13 = Suggested CFM.

Q: Do bathroom exhaust fans have to be vented outside?

When installing a bathroom fan, it is important to vent it to the outside, either through the attic or a sidewall. If bath fans are not vented outside, you’ll simply be moving the moisture to another area in the home, where it may cause problems.

Q: Can you run a bathroom fan all the time?

Running a bathroom fan all the time is not a good idea. If the fan is run for too long, it can cause the motor to wear down or even pose a potential fire hazard. Run the fan for about 20 minutes after bathing or showering to allow it to do its job and remove the moisture from the room, then turn the fan off.

Q: How long should you run the bathroom fan after a shower?

The Home Ventilating Institute recommends running a bathroom fan for about 20 minutes after showering. This amount of time will allow for proper bathroom ventilation and prevent moisture from lingering and causing issues.
