Best Bathroom Fan Reviews – Top Picks

1. NuTone 9093WH Deluxe Heat-A-Ventlite Heater

NuTone 9093WH Deluxe Heat-A-Ventlite HeaterWithout a doubt, it is quite unpleasant having to wake up in the morning to head to a cold bathroom. At the same time, it doesn’t make sense to heat the entire house, so that the bathroom isn’t freezing.
This unit warms the bathroom for you – and it accomplishes that almost instantly. Plus, you can select the desired temperature for your space, and the unit will evenly distribute the air so that the temperature is maintained.
That’s because it combines the functions of a heater and fan. The 1500-watt heating element performs excellently in spaces up to 100-square feet.
Concurrently, the 70-CFM ventilation works as expected. Another highlight of this unit is the inclusion of a 100-watt incandescent light. The 7-watt nightlight facilitates a soft glow. That is to say, it isn’t too bright, or too dim, making it ideal for nighttime visits to the bathroom.
In the meantime, note that the nightlight is 24/7. Hence, you don’t have to worry about turning it on or off, which is, of course, convenient.
You can depend on this unit to distribute the heat evenly around the room, primarily thanks to the electronically balanced centrifugal blower. A characteristic worth mentioning is the automatic reset thermal protection.
On the other hand, note that the instructions aren’t as comprehensive as they should be. Plus, according to former customers, the new design of the unit is much noisier than previous models.

2. Panasonic (FV-08-11VFL5) WhisperFit EZ Retrofit Fan

Panasonic (FV-08-11VFL5) WhisperFit EZ Retrofit FanA bathroom fan should have a wide range of key characteristics, in order to qualify as the best. Happily, this unit manufactured by Panasonic addresses these specifications, being a reliable unit.
As a rule of thumb, bathroom fans tend to be quite noisy – which is rather inconvenient, especially if the bathroom is located near a bedroom. However, the FV-08-11VFL5 is surprisingly quiet. At the same time, it’s worth outlining that the installation process itself is a breeze, which also comes as an advantage.
The construction of the fan features plastic, but it is of the highest quality, being really durable, as well. Also, in regard to its design, the fan facilitates ease of cleaning, as one of the sides can be easily taken off for this purpose.
Moving on, it also does an excellent job at moving the air around – which is, of course, the primary purpose for investing in a bathroom fan. Concurrently, you have the option of choosing your preferred airflow – 80 or 110 CFM.
Most importantly, though, this unit is designed in order to address upcoming Energy Star requirements. You also get a 4-watt night light, which, even though comes in handy, it is a bit too bright, as noted by some people.

3. RadonAway 23030-1 RP145 Radon Mitigation Fan

RadonAway 23030-1 RP145 Radon Mitigation FanOur first recommendation for the best bathroom fan is this mitigation fan that is energy-efficient as it operates ultra-quietly. So to speak, this unit respects all electrical code requirements, being suitable for residential and commercial use alike.
Most notably, this mitigation fan is thermally protected. Since it is ETL listed, it can be installed as an outdoor ceiling fan or indoors as well, depending on your individual needs.
In the case of most homes, the unit will follow three individual steps in order to diminish airborne radon: diagnostic evaluation, and the sealing and installation of the airborne reduction system. But how does it work?
Basically, the system changes the air pressure beneath the home and, afterward, by utilizing a radon fan that is specially designed, the radon gas is drawn out and filtered.
Most people that installed this mitigation fan were pleased with its results, as it brought a solution to high radon levels. With that in mind, if you find yourself in a similar position – you have a passive system engineered to vent the basement floor but it’s ineffective – then this unit might be the solution to your problem.
Still, in regard to the construction of the unit, there have been some complaints concerning its durability and the materials, which seem to be cheap.

4. Delta Breez SLM70 Slim 70 CFM Exhaust Fan

Delta Breez SLM70 Slim 70 CFM Exhaust FanThis unit is unbelievably compact for its performance, weighing less than 5 lbs. Another characteristic worth noting is how quietly it operates, which should definitely be appealing to most people. To be more specific, it operates at only 2.0 sones.
Being equipped with a potent DC brushless motor, this exhaust fan won’t let you down. The LED indicator light comes in handy, informing you when the unit is running. Meanwhile, the modern grille design is just as nice.
There are many advantages associated with the brushless motor – namely quiet operation, low power consumption, and long life. At the same time, you can choose to install the unit on the wall or on the ceiling, depending on what works best for you and your space.
Nonetheless, even if this isn’t necessarily noisy, this doesn’t mean you cannot hear it running. But, on the whole, the value it offers for the money is decent. Moving on, the unit is well-built, meaning that it’s likely to last for years.
On the other hand, keep in mind that the instructions aren’t as detailed as they should be, which can be a tad disappointing, especially if it’s the first time you’re installing this kind of unit.

Broan 678 Ventilation FanIf you’re looking for a conveniently-priced alternative, then this ventilation fan might be down your alley. Not only that it is a great budget choice, but it also delivers to its hype.

As for the shatter-resistant lenses, they are compatible with bulbs of up to 100 watts of power. Note, however, that you have to purchase that separately.
This unit is safe to use and, most notably, it is efficient – which is the first thing you should look for in a ventilation fan. In fact, it is UL listed, meaning that it is safe to use over showers or bathtubs, granted that it is connected to a GFCI-protected brand circuit. Simultaneously, the motor is permanently lubricated.
In lines with the manufacturer’s recommendations, you should use this with supply wiring that is rated for 90 degrees Celsius, at the very least.
Former customers have been happy with their purchase, especially due to the excellent price-quality ratio. Indeed, for the price, this ventilation fan is quite impressive. Once installed, it works well.
However, it is quite noisy. At the same time, the damper doesn’t close all the way due to the design, which could lead to letting house air outside.

At the same time, it would be safe to say that, considering the pricing of the item, it delivers a great efficiency level. Since this is quite small, and the airflow isn’t the largest, that makes it more than perfect for most bathrooms.
In regard to the installation process, most customers outlined that the steps were quite easy to follow, which is a major benefit. As far as the noise goes, it is decent, not too noisy that it disturbs you, or too quiet so that you don’t know when it runs.
Furthermore, the design is compact, which also comes in handy, as it doesn’t take up a lot of space. For example, it should work impeccably in spaces of up to 40 square feet. Are there any potential drawbacks with this device?
Well, perhaps the one disadvantage we could think of is that this isn’t suitable for larger spaces, but for a compact bathroom, it will work like a charm.

You will need to install a duct for this heater so that the fan can extract the moisture and expel it to outside your property.

Bathroom Fan Buying Guide

Bathroom Fan Reviews

You cannot expect to find the most reliable bathroom fan without considering a bunch of key elements, would you? There are many reasons why you should consider getting ventilation in your bathroom, but we’ll get to that later in the article. Now we’ll focus on the aspects you should keep an eye out for during the shopping process.

Top 5 Things To Consider Before Buying A Bathroom Exhaust Fan

  1. Size

    First, you’ll have to get the right fan for the size of your bathroom. This makes sense, doesn’t it? If you get a unit that is created for a smaller space and put it in a large bathroom, then you might end up disappointed by its performance.
    To that end, start by measuring the size of your bathroom – if you don’t know this already. As a rule of thumb, note that bathroom exhaust fans feature individual specifications. Thus, you should always assess the CFM rating to see the amount of air exchanged per minute.
    It is fundamental for the unit you pick to effortlessly handle the humidity accumulation that occurs in your space. Typically, a bathroom exhaust fan should have the CFM high enough, so that it is capable of replacing the air inside your bathroom at a rate of eight times an hour. So, it is crystal clear: the bigger your bathroom, the higher the CFM rating should be.
    In general, the CFM rating ranges from 50 to 110. Basically, for each foot of space, you must have at least one CFM. Therefore, granted that your bathroom measures 60 square feet, then a decent exhaust fan for your needs should have a rating of 60 CFM at the very least.
    Meanwhile, some bathrooms have higher ceilings – which is also worthy of consideration when picking out an exhaust fan. Many people overlook this important aspect, which makes them purchase a unit that doesn’t address their needs.

  2. Noise Level

    As you’ve seen in our reviews, we took the time to assess the noise level for mostly every unit. While this may not seem like a critical consideration at first, if you find loud noises inconvenient, this will turn into an annoyance for you.
    To that end, make sure you pay attention to this detail – as insignificant as it may seem. Expressly, the sound rating is measured in sones. Hence, if the number of sones is lower, then that would mean that the fan is quiet. On the other hand, if the sones rating is high, that would mean you’re dealing with a loud fan.
    Expressly, one sone is, for the most part, like the hum of a refrigerator in a relatively quiet kitchen. Usually, you’ll barely hear the sound of the refrigerator – which is all the point here.
    Usually, the quietest fans will have a noise level of 1.5 sones, or even lower than that. Of course, these units will also be pricier than other options that produce more noise. This is why your budget will most likely play a significant part in the entire shopping process – as it is with most purchases.

  3. Energy Rating

    Let’s move on to an equally important characteristic – namely the energy rating. Ideally, you should invest in a unit that doesn’t eat up a lot of energy. Not only that this is beneficial for the environment, but it’ll also reduce the sums on your energy bills.
    At the same time, there is a general misconception according to which larger fans consume more energy than smaller units. This is not true.
    What you have to do in order to assess this is to check the manufacturer’s specifications. As a rule of thumb, you should compare the energy ratings for more units and see which one seems like the most convenient option – in regard to its energy consumption, of course.

  4. Night Light

    Most of the bathroom fans we’ve reviewed beforehand come with this additional feature which, of course, comes in very handy. The lower-wattage night setting definitely comes in handy, as it will keep your bathroom slightly illuminated at night. This way, you won’t need to turn the light on at night. Most notably, though, most units use the minimum amount of energy for this extra feature.

  5. Mounting Options

    Depending on the layout of your bathroom, and the space you have at your disposal, you should pick a mounting option that would work best for your specifications. Usually, you can choose from two alternatives – namely a ceiling or a wall mounted fan.
    In order to position the fan on the ceiling, you should be 100 percent sure that it is strong enough to support the weight of the unit.
    To that end, do consider the weight and construction of the item, as well as the installation process. In general, ceiling fans come with individual brackets that aim at reducing the noise caused by the fan’s vibrations during its operation.

How Do You Size a Bathroom Fan?

Best Bathroom Fans We’ve already outlined the importance of picking out a bathroom fan that is according to the size of our bathroom. We’ve also included a range of key guidelines that should help you in that respect. However, we’d like to give you a bunch of more specific tips on sizing a bathroom fan, as this is crucial for the efficiency of the unit.
Installing a weak fan that doesn’t cope with ventilating the surface is simply not worth the effort. Usually, standard fan sizing is applicable to bathrooms that measure 100 square feet or less. As we’ve already said, you need 1 CFM per square foot.
To that end, how do you determine the square footage for your bathroom? What you should do in this respect is multiply the length times the width. For example, granted that your bathroom measures 9 feet in length and 6 feet in width, then the square footage would be 54. What does this mean?
In this case, the CFM rating for the fan you purchase should be of 54, at the very least. Ideally, you might oversize the fan, at least with a few CFM, for a boost of efficiency.
Nonetheless, there are other considerations worthy of your attention. If you have a jetted tub in your bathroom, or you have a separate room, you should get two fans.
Thirdly, even if your bathroom is smaller than 50 square feet, then you would still need to get a unit with at least 50 CFM rating. That’s because the minimum fan size is of CFM.

What If My Bathroom Is Larger?

Obviously, in the case of larger bathrooms, things are a bit different. If your bathroom has more than 100 square feet, then the exhaust fan has to be sized depending on the number of fixtures in your room. Hence, each structure has a specific CFM rating, as following: toilet (50 CFM), shower (50 CFM), jetted tub (100 CFM), and bathtub (50 CFM).
To that end, if you have a toilet and a shower, then you would need a 100 CFM fan. In the meantime, if you have a jetted tub, a toilet, and a shower, then you might consider investing in a 200 CFM fan.
On the other hand, if you have a high ceiling – namely a ceiling that measures above 8 feet, then you should use a different formula. The formula that applies in this scenario is the following: multiply the square footage by the height of your ceiling. Divide the result by 60 (minutes in an hour) and, afterward, multiply by 8 (the number of air exchanges per hour).

How to Install a Bathroom Exhaust Fan

What are the steps you should follow for installing a bathroom exhaust fan? When you want to install such a unit, there are some guidelines you should factor in. The same could be said about the evaporative coolers or the ceiling fans.
The installation process isn’t that complicated, granted that you know the specific steps you should follow. You can watch this video for a more comprehensive overview.

  • Identify the place where you want to install the exhaust fan. Afterward, you should mark it accordingly, to ensure that it fits. Granted that you want to install the unit on the ceiling, you should check whether that ceiling can support the weight of the item or not. At the same time, you should ensure that the place where you want to position it is free from electrical wires.
  • After marking the place for the installation, it’s time to proceed with making the hole. Use a drill to make a pilot hole first, and afterward, you should cut the hole by using a saw.
  • Finally, once you do that, you can proceed with the actual installation of the exhaust fan. Ensure that you keep the power cord over the motor. This way, your electrician will be able to reach it easily. As you hold the fan in place, you should tighten the screws. Afterward, you can position the cover over the fan.

Pro Tip: Essentially, you should attempt to DIY only if you feel confident and you have the skills to proceed with the installation process. Ideally, you shouldn’t be alone, as you’ll have to climb up a ladder, and someone might need to hand you the tools. At the same time, in order to protect your hands from eventual injuries, you should wear gloves. Concurrently, we advise you to wear protective eyewear for safety purposes.

How Do Exhaust Fans Work in Bathrooms?

Exhaust fans are amazing for bathrooms, especially if you’re looking to remodel the room, or just experience the benefits of such a device. Basically, these fans are meant to extract all moisture, odors and other similar things through the vent, ensuring a great bathroom environment. If they’re installed properly and you make sure to pick a high-quality model, you’ll enjoy the best parts of an exhaust fan.

Exhaust fans generally work similarly to ceiling fans. So, if you have a ceiling fan, it’s easy to imagine the basics of how the exhaust fan works. However, the difference is in the process that actually takes place. Whereas a ceiling fan simply circulates the air to make you feel cooler in a room, exhaust fans work the opposite way. They draw in moisture, bad smells, and anything that affects your bathroom.

They are installed either on the wall or the ceiling of a bathroom, allowing fresh air to make its way towards this room. In general, they should be connected to a metal duct, which leads outside, thus allowing the fan to expel moisture and odors outside and bring in the fresh air. In some situations, though, you need to make sure the ductwork is properly installed – otherwise, you will need to make some changes to ensure the air will actually go outside. If you don’t do this, then the air will just get expelled into the attic, where mold will start to form over time. Using an air freshener is also an alternative way to fight with the possible bad smell.

Through the ductwork of your home, the moisture will be expelled outside, after the fan passes it through. Since too much moisture is bad as it can lead to home insects, mold and other issues, the exhaust fans help you take it where it should be: outside. It is known that moisture causes mold to form over time, especially in harder to reach areas such as behind walls or under floor tiles. An exhaust fan will prevent this problem altogether, meaning you won’t have to invest in mold remedial.

All bathroom exhaust fans work similarly, but some may have more power than others, depending on the model. It all comes down to the product you choose, but overall they are all amazing devices.
Also, since nobody likes showering when there’s a bad smell in the bathroom, the exhaust fan will successfully get you rid of any odor.

Benefits of Installing an Exhaust Fan in A Bathroom

There are many benefits associated with installing an exhaust fan in your bathroom. In fact, you will most likely notice these benefits as soon as you’ve installed the unit in your bathroom. With that in mind, here are the main things you get with purchasing the best exhaust fan for your bathroom.

  • Enhanced Air Quality
    Categorically, this is one of the main benefits that come with purchasing an exhaust fan. Over the course of time, exposure to excessive humidity is likely to trigger asthma, as well as other respiratory problems.
    With that in mind, as exhaust fans eliminate the excess of moisture. This means that your tiles will be preserved in top condition for an extended timeframe.
    Furthermore, an exhaust fan will eliminate unwanted steam and odors. This inevitably translates into improved air quality.
  • Diminished Maintenance Costs
    Steam, humidity, and moisture, when excessive, will inevitably affect your house as well. And this doesn’t refer to your bathroom alone, but to the entire home, for a change. Moisture creates a perfect environment for the spread of allergens. These are likely to damage your drywall as well as your furniture. Here you will find the top-rated air purifiers for allergies reviewed by our editors!
    Therefore, by investing in a reliable exhaust fan, you can rest assured that you won’t have to deal with such problems.
  • Say Goodbye to Mold and Mildew
    Moving on, another benefit that comes with installing an exhaust fan into your bathroom is the fact that you won’t have to deal with mold and mildew. Once mold settles in your house, you must know that it can be a hassle to get rid of it. This is why you should consider making an investment in this direction and get an exhaust fan or, alternatively, a window fan.

  • What are the electrical requirements for bathroom fans?
    Depending on the unit, the electrical requirements will vary. For instance, if you pick a unit that also comes with heating functions, then you might require a dedicated circuit. On the other hand, a fan by itself can be typically operated from a light circuit.
  • Can I use the fan separately from the light?
    The greater majority of bathroom fans can be set up so that they operate independently on a separate switch from the light. That is to say, it is entirely up to you if you want to wire them together or not.
  • Where is the best place to install a fan?
    Presumably, the best spot for installing a bathroom fan is over the shower or the bathtub – depending on the layout of your space. Nevertheless, this doesn’t apply in the case in which your fan also comes with heating characteristics. We’ve also rounded up some of the top-rated bathroom heaters and space heaters’ in-depth reviews!
  • How often should I clean the fan?
    As a rule of thumb, fans have to be cleaned every three months or somewhere around that time. That’s because they typically create static electricity, which is likely to restrict air movement.
  • How Long Should You Leave the Bathroom Fan on After a Shower?
    Since there will be a lot of humidity in the bathroom after you take a shower, the fan should be left on for a while to make sure the environment is dry. There are many factors to consider when it comes to the amount of time required to clear moisture. More often than not, the power of the fan and the size of your bathroom could influence how much you should leave it on after you’re out of the shower.
    In general, it should take around 20 minutes to get rid of humidity and prevent condensation. But if your bathroom is bigger and the fan doesn’t have the highest power, it may require longer than that. Make sure to monitor the process, and leave the fan on until the humid air is gone and no condensation is forming. (Humidifiers bring many health and comfort benefits to your home. Our guide will help you choose the right dehumidifier for your needs.)
  • Can You Leave a Bathroom Fan on All Night?
    It is definitely not recommended to leave a bathroom fan on all night. Not only that it will make the air dryer than needed, but you don’t even need that much time to take out the moisture after a shower. Even if the fan is installed properly and is of high-quality, there is always the danger of overheating, which could end up in a fire. You don’t want to possibly damage or even lose your home, do you?
    The fan should run for about 20-30 minutes after you take a bath – time during which the humidity will be extracted and expelled outside. You should not allow it to run the entire night because in some cases, the ball bearings inside may lock up – this will end up in overheating and, if not turned off in time, can cause a fire.
  • Can I Put an Exhaust Fan Above My Shower?
    An exhaust fan can indeed be placed above a shower. Ideally, these fans should be positioned wherever the highest amount of moisture comes from, which is usually the shower or bathtub. Putting the fan above it will remove the annoying humid air much quicker and make sure it doesn’t reach the rest of the bathroom and create condensation.
    Usually, you can just place it above the place where you’re bathing, but it’s not unusual to install it anywhere near it either.
    Nevertheless, you should be careful at the fan you’re installing, because if it has a heating function, installing it above the shower may not be the right thing to do.
  • Do Bathroom Fans Use a Lot of Electricity?
    It all comes down to the size of the fan, the power it needs to do its job, and how much you leave it on for. Still, they do not use so much electricity in general and the costs are pretty low compared to many appliances.
    For example, some of them can only use like 6 watts, whereas other units that are bigger, faster and come with more features can rise up to 60 watts. So, while there is no specific amount of electricity for every fan, you need to consider all of the aspects when it comes to using your own unit. While simple ones only consume as much as a light bulb, others can consume more and thus add to your electricity bill.
