With so many bathroom exhaust fans to choose from, it can be very confusing working out which one is the best for your space.

Here are the 7 best bathroom exhaust fans to take the confusion out of the process.

Panasonic FV-0510VSL1 WhisperValue Ventilation Fan

Best Quiet Bathroom Exhaust Fan

This Panasonic exhaust fan has a low profile, so it sits as flush to the wall as possible to blend into the surroundings. It is our quiet choice, and you cannot get better than 0.3 sones. That’s a lower volume than rustling leaves.

It has a CFM range of 50, 80, and 100, so you can scale up and down the potency of the fan to cater to different moisture and odor levels. This exhaust fan also comes with a 10W LED strip panel and a 1W night light function.

Panasonic exhaust fans are Energy Star rated, so they are efficient, slimline, and quiet, and they also come with a 6-year warranty to give you peace of mind.

Pros

  • Slimline profile.
  • Super-quiet.
  • Speed selector.
  • LED light.

User Experience

This fan, with its sleek, low-profile design, is strikingly quiet, allowing you to forget it's even operating. The LED light is a clear step up from previous models, offering a bright, cool illumination that significantly enhances the room, and it comes with an added nightlight feature which can be quite handy. However, the installation process isn't the smoothest due to the fan's size and oval-shaped exhaust adapter, which requires some adjustments to fit 4" flex duct, making it more suitable for new work installations.

Delta BreezSignature VFB25AEH Exhaust Fan

Best Bathroom Exhaust Fan With Humidity Sensor

This Delta BreezSignature exhaust fan has the latest in brushless motor technology. It improves the efficiency of the engine while extending the life and runtime of the fan. It is louder than the Panasonic, coming in at a volume of 2.0 sones.

You can set it to humidity sensing mode at the wall switch. This detects when the humidity rises, and the unit switches on to start the extraction process. You can also disconnect the sensor so you can control the fan manually.

Thanks to the motor and the auto-humidity sensor, you can achieve a 74 percent saving in energy costs compared to other exhaust fans. It also has an impressive 130 CFM, meaning it will suit larger bathrooms.

Pros

  • Humidity sensor.
  • 130 CFM.
  • Energy Star rated.
  • Brushless motor.

Cons

  • Louder than some models.

Personal Perspective

I'm truly impressed with the performance of this fan in my bathroom. It effectively removes humidity, and the dual-speed modes, adjustable with a quick flip of the wall switch, are a nice touch - the blue light indicates low speed, while amber indicates high. It's comparatively quiet, even at high speeds, and the humidity sensor with automatic speed adjustment is a definite highlight, making it an efficient and user-friendly addition to my home.

Broan NuTone 765H80LB Exhaust Fan with Heater and Light

Best Bathroom Exhaust Fan With Heater

This bathroom exhaust fan offers just about everything. Not only does it have an LED light, but it also has an integrated 1,300-watt heater to keep you warm while you are in the bathroom. It also means you can combat moisture by maintaining a steady temperature to help dry the air.

This model has a maximum CFM of 80, so you might want to install it in small bathrooms, and you only get one speed, which forces you to run it at the maximum speed no matter what level of moisture and odor you have.

This Broan-NuTone has an operating volume of 2.0 sones, so it matches the Delta but is nowhere near as quiet as the Panasonic.

Pros

  • Integrated heater.
  • LED night light.
  • 80 CFM.
  • Ideal for small bathrooms.

Cons

  • Louder than some models.
  • Single-speed.

This Broan fan model is a decent replacement for an older unit, fitting perfectly into the existing ceiling cutout. Installing it involves a bit of work in the attic and a careful assembly of parts on a table beforehand. The fan operates effectively in a small bathroom, although it's not as silent as one might hope. The lighting element is a bit tricky as it holds the larger plastic cover in place and requires a specific bulb, but it's not a major issue. Despite a few unclear instructions, once installed, it works well in keeping the bathroom ventilated and warm, and the heater is a nice bonus feature.

Broan NuTone AER110RGBL ChromaComfort Exhaust Fan

Best Bathroom Exhaust Fan With LED Light

This Broan NuTone exhaust fan takes lighting to a new level. It’s like having your own disco in the bathroom. You can choose between 24 selectable colors via the wall control or millions of variations using the Bluetooth setting.

You can also dim the light between 10 and 100 percent to set the right mood when you are soaking in the bath.

It operates at 110 CFM, so it is suitable for medium-size bathrooms, and it runs at 1.5 sones, so while it isn’t the quietest, it is still a comfortable volume. This vent also utilizes DampSeal technology to reduce air leakage and backdraft by up to 50 percent.

You can also locate this fan over the dampest sections of the bathroom as long as you use the correct ground fault circuit interrupter (GFCI). It means you can capture the steam more efficiently, reducing moisture spread inside the bathroom.

Pros

  • 24 color choices.
  • Bluetooth enabled.
  • 1.5 sones.
  • Sealed system reduces air leakage.

Cons

  • Expensive.
  • Single-speed.

First-Hand Impression

I installed this bathroom vent, and I was immediately impressed by its style and the ease of the installation process. This vent offers amazing lighting and a powerful fan, although it does tend to be a bit loud. While the device pairing can be a tad tricky, it's not a significant drawback, and a quick dusting with anti-static spray maintains the cleanliness of the light portion. However, I found the Bluetooth switch for the light to be unreliable, requiring multiple presses to operate, and the app for setting the fan timer is not user-friendly and occasionally freezes.

Air King BFQ 110 Exhaust Fan

Best Budget Bathroom Exhaust Fan

If you are looking for a budget exhaust fan, this might be the best choice. It costs a fraction of the price of the most expensive models, making it incredible value for money. So, how good is it?

It’s HVI certified, has a special snap-in connection system for easier ceiling installation. It also has an operating volume of 3.5 sones, so while it isn’t the quietest ceiling fan, it still has an airflow of 100 CFM, making it ideal for bathrooms at about 100 square feet.

Like the previous model, you can install this fan directly over bathtubs and shower cubicles as long as you use the correct GFCI circuits. It doesn’t have speed selectors or LED lighting, but for a budget exhaust fan, it does what it says on the packaging.

Pros

  • Amazing price.
  • 100 CFM
  • Snap-in connectors.
  • HVI certified.

Cons

  • Limited features.
  • 3.5 sones.

User Experience

This Air King fan certainly stands out with its effective 100 CFM capacity, pushing a substantial amount of air and significantly improving the ventilation in my bathroom. Installing it did have its challenges as I had to enlarge the existing hole and put some real effort into securing the bracket, due to the tight corners of my bathroom. Although the fan does hang slightly below the ceiling, this isn't noticeable once the grille is in place and it doesn't detract from its overall appearance. While I was hoping for near silence, it's considerably quieter than the fan it replaced, and any noise seems to be mainly the sound of air moving rather than the fan itself. Despite some initial difficulties with the installation process, I'm satisfied with this fan's performance and quality, even if it's not as quiet as I'd initially hoped.

VIVOSUN 6-Inch 390 Inline Duct Fan

Best Inline Bathroom Exhaust Fan

Inline exhaust fans differ from bathroom varieties in the way they get used. These types of fans are better suited to more industrial applications, which is why they have a higher CFM value. This model has an airflow of 390 CFM, making it almost 4 times more potent.

It also has a fan speed of 2,550 RPM, which means you can move air throughout your space more effectively. It also has an operating volume of 37 decibels and a variable speed selector to scale up and down depending on the application.

If you want a powerful vent fan, this model is suitable for household, industrial and horticultural purposes. It is easy to install, is fluted at both ends to attach to ducting, and energy-efficient.

Pros

  • Easy installation.
  • 2,550 RPM fan speed.
  • Ideal for industrial, household, and horticultural use.
  • 390 CFM.

Cons

  • 37 dB (2.0 sones).

Personal Perspective

In my experience, this fan has proven to be remarkably resilient, functioning non-stop for over two years, maintaining a low noise level, and delivering excellent suction. However, I noticed that the fan's placement near a light source resulted in the housing melting, so cautious placement is advisable. While it does shift a large volume of air, the noise level, contrary to the advertised 38db, ranged from 50 to 62db under my experiment, which was a bit disappointing. On the bright side, this fan has served well in various settings, from a 4x4 tent to a 15x20 room, even performing admirably under my car's steering wheel to reduce sweat accumulation. However, it does have a notable humming noise that can be transmitted through connected ducts, so it may not be the best option for those seeking a silent operation.

Broan NuTone 682 Duct-Free Ventilation Fan

Best Ductless Bathroom Exhaust Fan

If you are on the lookout for a convenient exhaust fan, this could be the one. It has a charcoal filter, so it doesn’t need any ducting, making it a breeze to install. The best thing about charcoal filters is they also remove odors better than ducted systems.

You can fit this fan into the ceiling as well as the wall, giving you plenty of options. It even has plastic housing that is paintable to blend in with your color scheme.

You might find that this fan is only suitable for smaller spaces or as an additional fan in a larger bathroom to help with capacity. It is a zero-rated CFM model as it has no ductwork to channel the moisture outside.

The best thing about this exhaust fan is it is cheaper to install as it needs no ductwork.

Pros

  • Easy installation.
  • No ducting.
  • Ideal for small spaces.
  • Lower installation costs.

Cons

  • Limited power.
  • Zero-rated CFM.

Community Feedback

After using this ductless bathroom fan, I can say it's a suitable solution for spaces that lack external venting. The light, compact design allowed for easy installation, but some extra planning was needed due to the delicate material. The fan operates at a noise level that is quiet, yet ample enough to mask background sounds. While the fan functioned well in terms of air circulation, the flimsiness of the filter and its frame was a notable downside. Also, bear in mind that this fan isn't designed for removing moisture, making it more ideal for half baths or powder rooms.

Do Bathroom Exhaust Fans Really Work?

The Environment Protection Agency (EPA) states that each bathroom must have a mechanical means of extracting moisture if no window opens to provide ventilation.

So, if you want to extract moist air from inside your home, a bathroom exhaust fan is a crucial tool to achieve this. It works by a fan drawing air into the ducting located in the ceiling and pushing it to an outside vent.

There are many benefits of an exhaust fan. It stops damp penetrating the inside of your home. It prevents mold growth and mildew, as well as improving the air quality inside your bathroom.

How To Choose the Best Bathroom Exhaust Fan

So, what should you look for when you shop for a bathroom exhaust fan? Let’s consider some of the necessities.

Airflow Performance

Airflow is the single biggest consideration when shopping for that new bathroom exhaust fan. Airflow determines how potent your fan is, and is measured in cubic feet per minute (CFM).

The exhaust fan must have a minimum of 50 CFM for intermittent operation and 20 CFM for continuous use. While model codes do not cover the configuration and direction of the vent system, they do publish guidelines that require the vents to exhaust to the outside.

If you have a larger bathroom, you might need to scale up the fan size. Something closer to 100 CFM would be a better option to handle all the extra capacity.

Also, airflow determines the size of the fan relative to the room dimensions. An undersized fan will struggle in a large bathroom, impeding its performance and leaving you at the mercy of moist air.

Noise Levels

Not all bathroom exhaust fans are the same. You can buy standard fans that operate between 3.0 and 4.0 sones, which is the same volume as a conversation or radio playing at a moderate level.

Super-quiet models should be less than 1.0 sone. To give you a point of reference, 0.5 sones is the equivalent of leaves rustling.

What Fittings Do You Have?

The size of your bathroom fan not only correlates to room size, but also relates to what fittings you have in the room. If you have a shower, toilet, and a washbasin, you will likely create a lot less moisture than someone with an additional bathtub in the room.

And if you own a Jacuzzi bath, go for an oversized exhaust fan.

Location of the Bathroom Fan

Your bathroom has zones based on the moisture content in the room. A shower enclosure or bath might be the most water-laden areas of the room, so locating the fan closest to the epicenter of the dampness gives a better extraction performance.

Likewise, if you have recesses or awkward angles and corners in the bathroom, these all affect the way your fan works.

Wall or Ceiling

Where you locate your fan is crucial for the ease of installation. Wall fans are less complicated because all you need is a hole in the wall to insert the fan.

Ceiling fans vent to the exterior, either through a gable wall or the roof, which presents further complications. You need ducting and connectors, as well as a waterproof and wildlife-proof vent cover.

If you opt to vent through the roof, consider getting a professional to do the work.

Safety and Energy Performance

Make sure your chosen fan is certified by the Home Ventilation Institute (HVI) to ensure it is fit for purpose. These fans are tested for suitability and efficiency, and because the HVI is independent, you can trust the results.


Bathroom Exhaust Fan FAQs

How Many CFM Do I Need for My Bathroom Fan?

Your exhaust fan must have a minimum of 50 CFM for intermittent use and 20 CFM for continuous use. This is the bare standard set in law.

Does a Bathroom Exhaust Fan Help With Smell?

The primary purpose of a bathroom exhaust fan is to remove damp air from inside your home to the outside, but they also remove odors during that process. Odors linger in the atmosphere, so when you circulate the air in the room, it freshens the smells.

Is It Bad To Oversize a Bathroom Exhaust Fan?

It depends on what you mean by oversize. It is always a great idea to slightly scale up the CFM values to compensate for increased moisture and upgrades to bathroom fittings. If it calls for 50 CFM, choose an exhaust fan with at least 60 CFM.

However, don’t go too mad when sizing the fan. If you choose something with too much power, you risk increasing your energy costs and drawing all the heat and conditioned air from your home. It also increases the noise levels.

Which Exhaust Fan Is Better: Plastic or Metal?

Plastic exhaust fans are molded with rounded edges. They are lighter and cheaper. Metal fans are heavier and have sharp edges that could cause an injury if they fall or come off the roof.

Metal is also more susceptible to moisture damage and corrosion.

Can I Install a Bathroom Fan on the Wall?

As long as the wall is an external surface, you can install the exhaust fan in a sidewall. In some cases, it might be easier than opting to vent through a ceiling to the outside because it involves less work.

How Do I Know What Size Exhaust Fan I Need?

If you want to keep the air circulating in your space, get a fan that puts out no less than 1 cubic foot of air per minute per square foot. For an 80 square feet bathroom, you’ll want a fan with a CFM rating of 80.

Bath fans for smaller spaces are highly recommended for bathrooms with 50 square feet or less floor space. Thus, pick a fan with a CFM of less than 79 for your bathroom.

How Much Does It Cost to Have an Electrician Install a Bathroom Fan?

It depends on where you live, but having an electrician install a bathroom fan costs between $50 to $100 per hour. The price varies depending on where you live and the project’s complexity. It can take between two and four hours to install a bathroom fan.

What Kind of Pipe Do You Use to Vent a Bathroom Fan?

Experts suggest using a foam core PVC pipe for a bathroom fan. Gluing the fittings together ensures that any condensation inside the pipe will not seep out and drip through your ceiling or wall.

If you will utilize a snap-together metal duct pipe, ensure the horizontal seams are at the top of the pipe. Leaks are more likely to occur at the joints between straight pipe sections and at any angled fittings required when working with a metal pipe.

What is the Difference Between a Bathroom Exhaust Fan and a Ventilation Fan?

Exhaust fans are meant to extract odors from the bathroom and remove them, while ventilation fans will bring in fresh air.

Which Is the Best Exhaust Fan for a Bathroom?

The Panasonic FV-0510VSL1 WhisperValue is considered one of the best exhaust fans for a bathroom because it’s efficient and super quiet.

It includes a wide CFM range, so you may scale up or down the strength of the fan to adapt to varied levels of odor and moisture. It also has an adjustable speed control. This exhaust fan also features a night light capability with only 1W power and a 10W LED strip panel.


Banish Moisture and Odors

If you need to install a bathroom exhaust fan and are looking for options, this guide could be what you need. Exhaust fans are the best tools for extracting moisture and odors from the smallest room in your house.

The best fans protect against mold, mildew, and unsightly discoloration inside your bathroom.
