Everyone loves having a steamy shower once in a while, but many people forget to think about the damage that steam can do to a bathroom if it’s not taken care of. Thankfully, there’s a solution. Today, we’re going to help you find the best bathroom exhaust fan for you.
By installing a great exhaust fan, you can stop worrying about excess steam in your bathroom and instead enjoy your relaxing bathing time without a care in the world.
Our top pick is the Broan NuTone Flex. Not only is this fan incredibly efficient, making it great for those looking to keep their bills down, but it also does a great job at removing moisture.
Read on to find out more about what a bathroom exhaust fan actually does, why you should install one, and how to choose the right one for you.
What is a Bathroom Exhaust Fan?
Bathroom exhaust fans evacuate warm, moist air from a room and safely transfer it to the outdoors. They are by far the best method to remove excess moisture from a bathroom and are much more effective than simply opening a window.
An exhaust fan is a mechanical device that is typically operated via a switch on the outside of the bathroom. When switched on, the fan draws air out of the bathroom, before passing it through a flexible metal vent that leads to the exterior of the house.

Why Should I Install an Exhaust Fan?
Although having steam in the bathroom can be a positive thing (steam can promote healthy skin and clean pores), it can actually be quite damaging to the room. A moist environment can encourage rapid mold growth, as well as weakening the structure of walls and floors.
Since bathroom exhaust fans help remove this moist air, they also help prevent mold growth and structural damage. This is one of the biggest reasons why homeowners look to invest in an exhaust fan and is one of the main advantages of such a device.
This isn’t the only benefit of an exhaust fan. They also eliminate bad odors and generally improve the air quality in the bathroom. Additionally, you’ll find that your mirrors are much less likely to fog up when the fan is operating, which is an annoying situation that we’ve all experienced!

The extractor is available in two different airflow ratings, 80 CFM and 110 CFM. Whatever size of bathroom you have, you can be sure that there will be a version of the 7140-80 that’s perfect for you. Even with the larger 110 CFM size, the noise rating is kept below 1.5 sones.

Bathroom Exhaust Fan Buying Guide
When you first start looking into bathroom exhaust fans, you’ll quickly realize that there is plenty of choice on offer. Although this is great, it can also be quite overwhelming.
No need to worry though, by using this useful bathroom exhaust fan buying guide, you’ll easily be able to work out exactly which product you need to buy.
When you’re making an investment in any product, deciding on your budget is an important first step. By doing this, you’ll quickly be able to narrow down your options to a much more manageable number – there’s really no point spending loads of time looking at bathroom fans that are outside your price range.
Thankfully, when it comes to bathroom exhaust fans, there are great options available at nearly every price point. You don’t have to drop loads of cash to get a decent fan. In fact, there are some solid bathroom exhaust fans with price tags below $20!
Of course, as you spend more money you typically will get more premium features, such as a humidity sensor or greater air-flow capacity. However, if you’re just looking for a basic fan that gets the job done, you’ll still have plenty of products to choose from.
CFM stands for cubic feet per minute. The CFM rating describes how much air an exhaust fan can shift in a given amount of time. The higher the CFM value, the more moist air the fan will be able to remove from the bathroom.
The CFM rating is affected by a few different factors. These include the power of the fan’s motor, the shape and length of the blades, and the overall design of the vent unit.
Although CFM is important for a bathroom exhaust fan, it definitely isn’t everything. A fan could have a very high CFM rating, but use loads of energy in the process. This is where the efficiency of an exhaust fan comes into play.
The efficiency of a bathroom exhaust fan determines how much energy the fan uses whilst it operates. Ideally, you want to look for a fan that keeps the efficiency as high as possible, whilst still offering enough power to maintain a solid CFM rating.
The balance of CFM and efficiency is an important process for manufacturers and is an area that has seen quite a lot of innovation in recent years. These days, it’s pretty common to find very effective exhaust fans that don’t suck up tons of electricity and energy.
If you want to ensure that your bathroom exhaust fan isn’t going to be a drain on your energy bills, then make sure to look into the airflow efficiency before you buy.
When you’re settling down for a lovely relaxing bath, the last thing you want to hear is an exhaust fan buzzing away in the ceiling. The very best bathroom exhaust fans will keep excess noise to an absolute minimum, whilst performing their task efficiently and effectively.
Exhaust fan noise is usually measured in ‘sones’, and every fan is given a sones rating. The higher the rating, the louder the fan is when it’s in operation. For context, the gentle humming of a fridge is around 1 sone, whereas a normal conversation is typically 4 sones.
If you want your bathroom to be as peaceful as possible, then choosing a bathroom exhaust fan with a low sone rating is essential.
When you’re buying a bathroom exhaust fan, it makes sense that you’ll want it to last for many years to come. For this to be the case, it’s important to find a fan that is built to a high standard and out of great materials.
Many people assume that you have to invest more money to achieve this. Although this is sometimes the case, there are definitely some affordable bathroom exhaust fans that provide the quality without the hefty price tag.
All of the options that we’ve included in our list are built to a high standard, and you really can’t wrong with any of them. That being said, we’d still recommend that you check out other customer reviews before buying to see what they have to say about the durability and quality of the product.
Extra features are the additional functions and tools that manufacturers add to their bathroom fans in order to help them stand out from the competition. Common additions include humidity sensors, motion sensors, a speed selector switch, or an LED indicator light.
None of these things are necessary for a great bathroom exhaust fan to have, but you’ll find the user experience more pleasurable if you do have them. Sensors in particular are great additions since if you forget to switch the exhaust fan off, it will automatically stop and you won’t be wasting loads of energy.
Hopefully, you now have a better idea of which bathroom fan is the best for you, or a least feel more comfortable in knowing what to look for.
The last thing we’d say is that it’s important to remember that the best bathroom fan for one person might not be the best for you. Just make sure that you take all of the important factors into account before you buy!
What is the best exhaust fan for a bathroom?
Since there are so many great bathroom exhaust fans on the market, it’s actually pretty hard to say which one is the very best. In our article, we named the Broan-NuTone Flex AE110LK as our number one pick, but all of the exhaust fans we reviewed are excellent choices.
If you’re struggling to work out which is the best bathroom exhaust fan for you, then be sure to read through our buying guide above. There, you’ll find out everything you need to know about bathroom fans and the features to look out for.
How many CFM do I need for my bathroom fan?
The CFM rating that you need will depend entirely on the size of your room. The general rule is that you should have 1 CFM for every square foot of room space. So if your room is 40 square feet, then you’ll need an exhaust fan with at least a 40 CFM rating.
To calculate the square footage of your bathroom, simply multiply the length and width (in feet) together. If you don’t get a fan with a high enough CFM level, then the fan is going to struggle to replace the moist air in your bathroom at a fast enough rate, and it won’t be able to do its job properly.
Is more CFM better bathroom fan?
The higher the CFM, the more air a bathroom fan can move out of a room. Although you might think having the highest possible CFM is the best, this isn’t necessary in most cases. You only need a fan that is powerful enough for the size of the room that it’s circulating – more CFM isn’t going to have much of an extra impact.
The rule of thumb is that you should have 1 CFM for every square foot of room space. Therefore, if your bathroom measures 10 x 8 feet, then you need a fan with a CFM value of at least 80.
Who makes the quietest bathroom exhaust fan?
These days, bathroom fan manufacturers recognize that the noise output of their products is an important factor for buyers. As a result, many modern bathroom fans are pretty quiet, and you have plenty of choices if this is one of your criteria.
One of our favorite quiet bathroom fans is the Panasonic WhisperFit EZ, which we reviewed in our list above. This particular bathroom exhaust fan manages to effectively remove moisture and odors from a room, whilst hardly making any noise.
