Best Wall Exhaust Fan

How to Find the Best Wall Exhaust Fan

Exhaust fans are necessities for bathrooms because they help manage odors and vent moisture that can build up when you bathe or shower. Leaving humid air in your bathroom can lead to mold, cause corrosion, and damage paint or wood.

The criteria I used to select the best exhaust fans listed in this article include fans that have excellent features, reasonable prices, gorgeous design, and perhaps all three. Each fan has its own strengths, but I choose quality products you can trust.

Best Wall Exhaust Fan Buying Guide

While some areas have building codes that dictate how you can use bathroom ventilation, others don’t. You also want to make sure you pick a fan that fits the size and function of your bathroom and pay attention to aesthetics and noise level.

Local codes

Some local building codes require that all bathrooms have an exhaust fan, but they may also require a minimum capacity or a particular size circuit for the type of fan you use. Check your local rules to make sure you install your exhaust fan correctly based on whether it has a light or a heat lamp combination feature.

You may even have to draw a permit to install it, so check with the permit department in your area to make sure you have everything you need before getting started.

Bathroom size

You need to choose an exhaust fan of the appropriate size for your bathroom. If the fan is too small, it won’t work as efficiently as it should. If it’s too big, it could create a draft that will make you cold while you dry off.

In some cases, two fans are recommended, so do some research on the size and configuration of your bathroom before you purchase anything.

Sound ratings

Quieter fans will have a lower sound rating. For some, noise doesn’t matter when switching it on after a hot shower, but for others who may want to run it while taking a relaxing bath, a noise rating of 1 or less will offer a quieter experience.


While most exhaust fans are very simple in design, some aren’t very discrete. Depending on the look you’re going for, you may want to choose an exhaust fan with a particular design that fits in with your bathroom style better.

Some designs blend in while others stand out, so what you choose will depend on whether you want to make a statement or ensure that your exhaust fan isn’t noticeable at all.


Exhaust fans offer features other than just a way to eliminate moisture and odors. If you’re willing to increase your budget, you can find fans that also have lights, heaters, automatic humidity sensors, and even built-in bluetooth speakers.

If you’re looking for the right exhaust fan for your bathroom, or maybe even a kitchen, there are plenty of options. These frequently asked questions could help you make a better decision.

Question: How do I choose an exhaust fan?

Answer: Aside from aesthetics and extra features, which is a highly personal choice, you should keep in mind that you need at least 1 CFM for every square foot of space in the room. This should give you a better idea of how powerful the fan should be.

If your bathroom is square, multiply the width by the length. However, if you have an odd shaped bathroom, you can simply measure the bulk of the space and estimate, or measure it in sections and then add them all together.

Question: What is the difference between an exhaust fan and a ventilation fan?

Answer: An exhaust fan works to remove pollutants from the air, which helps to eliminate moisture and odors. A ventilation fan simply brings clean air into the space from an outside source, which will keep your room feeling fresher and less stagnant, but may not remove moisture or odors as effectively.

Question: Which exhaust fan is better, plastic or metal?

Answer: For a bathroom, exhaust fans with plastic blades work better because they won’t rust with prolonged exposure to moisture. However, if you want to remove heat or odors from the kitchen, a fan with metal blades is best because it’s easier to clean.

Question: Can you use a regular fan as an exhaust fan?

Answer: If you’re having trouble getting a permit to install an exhaust fan or you simply need to expel odors temporarily rather than all the time, you can use a regular fan to do it. Perhaps you simply experienced a mishap in the kitchen or you’re dealing with a visitor who smells like smoke.

Simply use a table fan to suck up the air and blow it out an open door or window. If you point it in the right direction, you can achieve an exhaust-like performance.
