Although having a low noise output is great, the ventilation performance is just as important. Thankfully, the WhisperFit doesn’t drop the ball in this area, offering fantastic moisture removal and a high airflow capacity.

A cool feature with this particular bathroom fan is that you can switch between different CFM levels. You can choose between 80 and 110 CFM, depending on how fast you need the fan to be running. This is actually quite a rare feature and isn’t offered by many other exhaust fans.


  • Speed selection switch – so if steam builds up, you’re able to clear it with a higher speed.

This model from ESD Tech is yet another bathroom fan that has been designed to minimize noise production.

This rating means the device is quieter than the hum of a refrigerator, so you probably won’t be able to hear anything whilst you’re reclining in the bath.

This ESD Tech ventilator is a solid solution for anyone that is experiencing problems with humidity in their bathroom. The powerful fan draws in moisture-dense air and quickly passes it to the outside of your house.

If you’ve already got a vent installed in your wall, then setting up the ESD Tech fan is an absolute breeze. It has been designed for use with a standard 6-inch duct but comes with an adapter for installation inside a 4-inch duct.

The next option that we have for you is the 7140-80 model from Homewerks. This bathroom fan has a ceiling-mounted design, which means it probably won’t be suitable if you have an in-wall ventilation duct. That being said, if you do want your bathroom fan in the ceiling, the 7140-80 is a solid choice.

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.

This product is available at a range of airflow levels, stretching from 90 CFM all the way up to 150 CFM. The 150 CFM version is particularly impressive since it manages to retain very low excess noise production, despite the incredible amount of airflow power.

The KAZE APPLIANCE Ultra Quiet is typically compatible with existing ventilation ducts, but you may have to use the included adapter in some cases.


  • Rapid moisture removal – quickly removes steam before it causes damp build-up.
  • Quiet performance, even with high air-flow models – ideal for those who need high power for a large bathroom, but also want low noise.

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 Rating

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.

Noise Production

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

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.

Check out our list the best exhaust fans with a heater and light to find some options with fancier features.

Final Thoughts

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 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.
