A good exhaust fan is a bathroom must-have, not only to manage odors but also to properly vent hot, moist air that builds up as you bathe or shower. This humid air can lead to mold, cause corrosion to fixtures, and even damage painted and wooden surfaces. 

In many areas, building codes require bathroom ventilation, so you’ll want to know the rules in your area. When choosing a bathroom exhaust fan, be sure to pick one that corresponds to the size of the bathroom. You will also want to decided if you need any additional features, and if the vent’s look or noise level matters to you.

Below, you’ll find the best bathroom exhaust fans available on the market. 

Best Overall: Delta Breez Slim Series 70 CFM Wall or Ceiling Bathroom Exhaust Fan

Delta Breez Slim Series 70 CFM Fan
What We Like
  • Provides sufficient airflow without noisy operation

  • Can handle bathrooms up to 70 square feet

  • Energy efficient motor

What We Don't Like
  • Does not come with a room light

If you’re looking for a bathroom fan that provides sufficient airflow without noisy operation, consider the popular Delta Breez SLM70H. This fan is described as a “sanity saver” by homeowners fed up with noisy bathroom exhaust fans.

With a power level of 70 cubic feet per minute (CFM), this fan will handle bathrooms up to 70 square feet in size. It features a brushless DC motor that’s energy efficient and reliable thanks to “soft start” operation that allows the fan to quickly but smoothly reach full speed.

The unit operates at 2 sones and includes an indicator light as visual confirmation that the fan is on. Though Delta describes this fan as ‘virtually silent,’ there's still some audible noise.

Best Budget: Broan 688 Ceiling and Wall Ventilation Fan

What We Like
  • Efficient and affordable

  • Best fit for bathrooms under 50 square feet

  • Easy to install

What We Don't Like
  • Limited CFM may not be best for all bathrooms

Blast odors and increase circulation without blowing your budget on a pricey bathroom exhaust fan. Broan makes an efficient and affordable bathroom exhaust fan that's a good pick for homeowners on a budget.

The Broan 688 is rated for 50 CFM and is best fit for small bathrooms of under 50 square feet. It earns frequent praise in reviews for being especially easy to install and can be mounted in the ceiling or wall. However, the somewhat limited CFM may not be the best fit for bathrooms in need of serious moisture management.

This budget bathroom exhaust fan operates at about 4.0 sones, which is considerably louder than other models. Some people find the increased noise level to be a good match for providing bathroom privacy. The bottom line is that this bathroom exhaust fan is great for tight budgets and smaller bathrooms.

Best with Light: Broan-NuTone 110 CFM Ventilation Fan with Soft Surround LED Lighting, 1.5 Sones; ENERGY STAR

NuTone InVent Series 110 CFM Exhaust Fan with Light
What We Like
  • LED light can be wired separately or with the fan

  • 12W LED light rated for 25,000 hours of use

What We Don't Like
  • Relatively quiet but not silent

This model from NuTone’s InVent series provides 110 CFM to provide abundant air movement combined with a soft surround LED light you can wire separately or together with the fan.

The built-in LED light runs around the perimeter of the exhaust fan grill for even light distribution. Unlike some other models of bathroom exhaust fans that have a light feature, users find that this model is bright enough to light the bathroom, even as a standalone light source. You won’t need to worry about replacing the light source anytime soon—the 12W LED light source is rated for 25,000 hours of use.

!f you’re concerned about removing moisture from the air, keep the area this fan is serving to 110 square feet or less. The fan operates at around 1.5 sones, making it relatively quiet, but not silent.

Best with Humidity Sensor: Air King Humidity Sensing White 80 CFM 0.5 Sone Ceiling Bath Fan

Air King Humidity Sensing 80 CFM Ceiling Bath Fan
What We Like
  • Integrated humidity sensor

  • Energy-star certified efficient operation

  • UL-listed for damp environments

What We Don't LIke
  • Larger than other models

A primary purpose of bathroom exhaust fans is to control humidity. But what if you forget to flip the switch to turn the fan on or the humidity levels climb when no one is around? You may want to consider a bathroom exhaust fan with a humidity sensor so you can never worry about elevated humidity levels again.

This model from Air King moves air at 80 CFM and operates at just 0.5 sones, but what really sets this fan apart is the integrated humidity sensor. You can program it to kick on when the room surpasses a preset humidity threshold (as high as 80 percent).

Other important things to know about this fan is that it’s Energy Star-certified for efficient operation and is UL-listed for damp environments (like above the shower). It can be installed in rooms up to 80 square feet. Some reviewers did mention that the fan is a little larger than expected, but that it wasn't necessarily a dealbreaker.

Best with Heater: Broan-NuTone 9093WH Exhaust Fan, Heater, and Light Combo

What We Like
  • Model includes an exhaust fan, onboard heater, and light

  • 1500-watt heater

  • Includes a four function wall switch

What We Don't Like
  • More expensive than other options

Heat things up while keeping moisture away, thanks to a bathroom exhaust fan with heater—like the Broan 9093WH. This combo model includes an exhaust fan, onboard heater, and light.

Step out of the shower or warm up your morning routine with the help of the 1500-watt heater that provides a direct source of heat into your bathroom. A 100-watt incandescent bulb provides plenty of light power to illuminate the room, while the 7-watt night light is just bright enough to help you find your way in the middle of the night. The 70 CFM exhaust fan provides sufficient air movement for bathrooms up to 65 square feet. The unit includes a four-function wall switch that lets you operate each function separately.

Best Design: Hunter Home Comfort 83002 Ventilation Sona Bathroom Exhaust Fan

What We Like
  • Looks more like a conventional light fixture

  • Motor capable of moving 110 CFM

  • Uses two 60-watt light bulbs for illumination

What We Don't Like
  • Frosted coating on the dome diffuses the light

For an incognito bathroom exhaust fan, consider the Hunter Sona Bath Fan with Light. This decorative exhaust fan looks more like a conventional flush-mounted light fixture, but inside is a motor capable of moving 110 CFM. It’s a top choice if you’re designing a bathroom that is beautiful and functional.

The Hunter Sona uses two 60-watt light bulbs to provide illumination and includes the option to install a smaller 7-watt bulb for a soft nightlight. People agree that this exhaust fan for bathrooms looks beautiful and could easily be mistaken for only a light fixture. However, the frosted coating on the dome does diffuse the light, so you will need a second source of light in the bathroom as well.

At 3.0 sones, this bathroom exhaust fan is considerably louder than some other top models.

Best Duct-Free: Broan 682 Duct-Free Ventilation Fan

What We Like
  • Contains a charcoal filter to absorb odors

  • Great choice for basement bathrooms

  • Improves air circulation and clears odors well

What We Don't Like
  • May not meet some building code requirements

  • Isn't recommended for larger bathrooms

If you don’t have access to an external vent but still want to improve circulation and air quality, consider a duct-free bathroom exhaust fan. The Broan 682 utilizes a fan to produce air movement and a charcoal filter to absorb odors.

A duct-free bathroom fan is a good choice for basement bathrooms or bathrooms with no attic access (just note they may not meet building code requirements in some areas). In lieu of an external vent, the hardwired fan moves air across a filter to purify it before recirculating it in the space. That means the fan does a good job of improving air circulation and clearing odors in powder rooms and half baths but isn’t recommended for larger bathrooms or for controlling high humidity levels.

Because the unit doesn't hook up to a duct, the product description doesn't include how much noise it produces but keep in mind that it’s not a silent unit.

Best Quiet: Panasonic WhisperCeiling DC Fan

Panasonic WhisperCeiling DC Fan
What We Like
  • One of the quietest bathroom exhaust fans on the market

  • Perfect for rooms of multiple sizes

  • Easy to install

What We Don't Like
  • More expensive than other options

Panasonic makes some of the most popular models of bathroom exhaust fans, and the brand has a reputation for quiet operation. It lives up to this reputation with the Panasonic WhisperCeiling DC Fan.

This versatile bathroom exhaust fan is perfect for rooms of multiple sizes thanks to the Pick-a-Flow Speed Selector that adjusts fan operation between 50, 80, or 110 CFM. To live up to its quiet name, this model is rated to operate at 0.3 sones—making it one of the quietest bathroom exhaust fans on the market. Room-side installation is easy, thanks to Flex-Z fast brackets that allow you to mount the unit without having to crawl into your attic.

As for its ability to clear moisture from the bathroom, people are very happy with its performance. Many users report that the fan does a great job of removing moisture from steamy showers and keeping mirrors fog-free. It’s rated for use in bathrooms up to 110 square feet, and is Energy Star rated for efficiency.

What to Look for in a Bathroom Exhaust Fan

Local Building Codes

Your local building codes may mandate that all bathrooms must have an exhaust fan, and may also require fans to meet a certain minimum exhaust capacity as well as other requirements. It’s important to check with your local permitting department. 

Bathroom Size

It’s important to pick an exhaust fan that correlates to the size of your bathroom. A fan that’s too small won’t be effective, but a fan that’s too powerful might create unpleasant drafts. In some cases, a second fan might be recommended. 

Sound Ratings

The lower the sound rating, the quieter the fan. If you only plan to switch on the fan after taking a quick shower, the noise level of the fan may not be important to you. However, if you want to run your exhaust fan while taking a relaxing bath, look for a fan with a rating of 1.0 or less. 


Most exhaust fans have a simple and discrete grate, but others have more elaborate or noticeable designs. You may want to find one that fits with the style of your bathroom.


Some bathroom exhaust fans offer a number of additional functions in addition to venting, if you’re willing to spend more. You can find fans that also function as lights, heaters, or even have built-in bluetooth speakers. Some also feature automatic humidity sensors.
