Best Exhaust Fan for Garage

Maxx Air Powerful Industrial Exhaust and Ventilation Fan

This garage exhaust fan is a perfect mix of value and quality that will for sure keep your garage cool and smell-free.

What I Like

I love that this exhaust fan will take care of regulating the heat, fumes and smells inside of your garage. It’s made out of galvanized steel which will protect it from rust on the inside and outside.

When it’s not in operation, you have the ability to shutter the exterior. This is great for the winter times when you want to turn on your garage heater and stay warm. Once you’ve had enough of the heat, open the shutter back up and let all the built-up garage air outside.

You can decide between 14, 18, 24, and 36 inch models depending on how big your garage is. The bigger it is, the bigger the ventilation fan you want to help remove unwanted odors, humidity, and heat.

It also comes with a 1-year warranty that will keep you protected should anything go wrong.

What I Don’t Like

It doesn’t come with a screen to keep out bugs but you can DIY one easily yourself. It can also be a bit loud. Be sure to measure in between the studs in your garage as well so you can install it without an issue.


I think if you’re OK with this fan being a little bit loud when in use but want a high-end exhaust fan for your garage, this is your best bet. Make sure you get the right size before you purchase and you should be set.

  • Comes in different sizes to fit your garage perfectly
  • Has a shutter for the winter
  • Comes with a one year warranty
  • Can be a bit loud

Best Heavy Duty Exhaust Fan for Garage

iLIVING ILG8SF20V Wall Mounted Exhaust Fan, 20″

This heavy-duty garage exhaust fan is going to blow you away!

What I Like

This heavy-duty garage exhaust fan will cut down your cooling costs if you decide to cool down your garage during the summer. With all the hot air being trapped inside of your garage, even a garage fan won’t be able to help you get the temperature down. The rooms adjacent to your garage will also enjoy lower temperatures, reducing the bill at the end of the month.

The motor is kept permanently lubricated for longevity and it’s fully enclosed so no birds and rodents can mess with your exhaust fan. It’s corrosion-resistant so it’ll hold up even when it gets wet.

Once you’ve had enough ventilation, you can turn the shutter down so you can heat your garage during the winter.

What I Don’t Like

Some users report that the motor fan gets super hot which can lead to damage if left on during the extreme winter months. It gets a bit loud as well when using, so keep that in mind.

If you want to add in the variable speed controller, it can cause your unit to hum at an unreasonable rate. If you don’t care about the variable speed controller then this doesn’t become a deal breaker.


Once you install this bad boy you’ll be enjoying 20″ of heavy duty exhaust fan power. Even the biggest, hottest garage will be cooled down and give you the options to upgrade your garage’s air conditioning and heating.

  • 20 inches of fan speed
  • Option to upgrade with a programmable controller/thermostat
  • Corrossion resistant
  • Can be loud
  • Variable speed can make the fan hum louder than normal

Best Budget Exhaust Fan for Garage

KEN BROWN 12 Inch Variable Shutter Exhaust Fan 

This budget garage exhaust fan comes with a wall-mounted variable speed controller while the more expensive options don’t! You’ll be able to cool down your garage in style this summer.

What I Like

I love the variable speed controller that this exhaust fan comes with. It’s going to give you the control you need when you need to remove heat, wood dust, smells, and humidity. During spring you may not need a full-speed exhaust fan annoying you, and with the controller, you’ll be able to decide how much it works and when.

You won’t have the annoying job of unplugging your exhaust fan when you want to turn it off, you can do that easily with the speed controller. You can also decide to run it without the speed controller but it will run at full speed if you wish to do so.

It’s made out of high-grade aluminum to prevent corrosion and it’s able to withstand moisture and high temperatures. You’ll want an exhaust fan that can withstand the elements and this housing does just that.

The shutters are automatic as well and close when the fan isn’t in operation. The more expensive options seem that they lack features compared to the value this garage exhaust fan offers.

What I Don’t Like

The fan can vibrate at higher speeds over 80%.


This budget exhaust fan is a great choice to cool down your garage. Whether you’re after the variable speed controller or the automatic shutters, you’ll be able to cool down your garage in style.

  • Variable speed controller
  • Automatic shutters
  • Budget price
  • Can vibrate loudly at higher settings
