10 Best Dehumidifiers for Garage of 2022

Dehumidifiers For Garage buying guide


A garage often becomes a dumping ground for all the things we don’t need in our homes. That’s why it’s important to have a good dehumidifier in your garage. Here’s a buying guide to help you choose the best one for your needs.

There are two main types of dehumidifiers- those that use electric coils and those that use condensation to remove moisture from the air. Electric coil dehumidifiers are less expensive than condensation models, but they’re not as efficient. Condensation models are more expensive, but they’re more energy-efficient and can handle larger spaces.

When choosing a dehumidifier for your garage, make sure to pick one that’s the right size for the space. If you have a small garage, a portable dehumidifier will do the job. But if you have a large garage, you’ll need a larger unit.

Be sure to also consider the features you want in a dehumidifier. Some models come with timers, humidity sensors, and automatic shut-off features. These features can be helpful if you’re not using your garage all the time and want to save energy.

Finally, check the warranty before you buy. Dehumidifiers are built to last, but it’s always good to have a warranty in case something goes wrong.

What is a dehumidifier?

A dehumidifier is an electrical appliance which is used to remove moisture from the air, most commonly for the purpose of reducing the level of humidity in a room or building. Dehumidifiers are often used in domestic and commercial environments in order to prevent the growth of mold, mildew and other harmful bacteria. In industrial settings, dehumidifiers are used to prevent corrosion of metal components and machinery.

How does a dehumidifier work?
A dehumidifier works by pulling in air from the room or building and passing it over a cold coil called a condenser. As the air passes over the condenser, the water vapour in the air condenses on the coil and is collected in a water tank. The dry air is then passed over a hot coil called an evaporator where it is heated and circulated back into the room or building.

What are the benefits of using a dehumidifier?
There are many benefits of using a dehumidifier in both domestic and commercial environments. By reducing the level of humidity in a room or building, you can:
-Prevent the growth of mold, mildew and other harmful bacteria
-Reduce musty smells caused by excess moisture
-Eliminate condensation on windows and walls
-Protect furniture, clothing and electronics from damage caused by moisture

How does a dehumidifier work?

Dehumidifiers work by pulling in damp air and passing it over a cooling coil. As the air is cooled, water droplets condense on the coil. A fan then draws the now-dehumidified air over a heating coil and back into your room.

The benefits of using a dehumidifier in your garage

Using a dehumidifier in your garage has several benefits. A dehumidifier will help to:
-Reduce the amount of dust in the air
-Eliminate musty odors
-Prevent the growth of mold and mildew
-Protect your stored items from moisture damage

A dehumidifier can also make your garage a more comfortable place to work in by reducing the amount of humidity in the air. If you live in an area with high humidity, a dehumidifier can also help to reduce the risk of condensation and mold growth on your walls and ceilings.

How to choose the right dehumidifier for your garage

Choosing a dehumidifier for your garage can seem like a daunting task, but it doesn’t have to be! There are a few things you should take into consideration before making your purchase. This guide will cover everything you need to know in order to choose the right dehumidifier for your garage.


Choosing the right dehumidifier for your garage starts with understanding how much space you need to cover. Dehumidifiers are sized by how many pints of water they can remove from the air in a 24-hour period. A pint is equal to 16 fluid ounces or 473 milliliters. To find out how many pints you need, multiply the length of your garage by the width and then multiply that number by the height. This will give you the cubic footage of your garage. Once you have that number, divide it by 1,000 to find out how many pints you need to dehumidify your garage in a 24-hour period.

For example:

A 20-foot long, 10-foot wide, and 8-foot tall garage is 1,600 cubic feet.
1,600 divided by 1,000 equals 1.6
You would need a dehumidifier that can remove 1.6 pints of water from the air in a 24-hour period


If your garage is less than 1,500 square feet, a 25-pint unit should suffice. If your garage is between 1,500 and 2,000 square feet, you might want to consider a 30- or 33-pint unit. If your garage is greater than 2,000 square feet in size, you might need to purchase a commercial dehumidifier or two smaller units that you can operate at the same time.

Another factor that will help you determine the size of the dehumidifier you need is the number of people who regularly occupy the space. For example, if two people work in a 1,500-square-foot garage every day, you might want to purchase a larger unit than if only one person worked in the space.

Power source

There are two types of power sources for dehumidifiers: electric and gas. Most dehumidifiers are electric, which means they need to be plugged into an outlet. Gas-powered dehumidifiers, on the other hand, don’t need an outlet and can run on either propane or natural gas.

If you have a garage with an outlet, then an electric dehumidifier is the way to go. They’re less expensive and easier to maintain than gas-powered models. However, if your garage doesn’t have an outlet or if you want a dehumidifier that can run on its own power source, then a gas-powered model is your best bet.


Drainage is critical with a dehumidifier, especially if you plan to use it in your garage. If the dehumidifier does not have a drainage system, the water will simply build up in the unit and eventually spill out onto your floor. A dehumidifier with a drainage system will allow you to direct the water into a nearby sink or drain, making it much easier to maintain.

Additional features

In this guide, we’re going to take a look at some of the additional features that you may want to consider when purchasing a dehumidifier for your garage. Some of these features are must-haves, while others are simply nice-to-haves. We’ll also give you a few tips on how to get the most out of your new dehumidifier.

Additional features to consider:
-Automatic shut-off: This feature will cause the dehumidifier to shut off automatically when the desired level of humidity is reached. This is a great feature to have if you’re forgetful or if you don’t want to constantly check on the dehumidifier.
-Humidistat: This feature allows you to set the desired level of humidity. Once that level is reached, the humidistat will automatically turn off the dehumidifier.
-Low temperature operation: This feature allows the dehumidifier to continue operating in low temperatures (as low as 41 degrees Fahrenheit). This is a great feature to have if you live in a climate where the temperature in your garage can dip below freezing.
-Timer: This feature allows you to set a timer so that the dehumidifier will automatically turn on and off at specific times. This is great if you only want the dehumidifier to run during certain hours of the day.
-Drainage options: Many dehumidifiers come with drainage options, such as a hose or bucket connection. This is great if you don’t want to empty the water reservoir on a daily basis.
