How to Choose the Best Dehumidifier for a Garage

Will High Humidity Affect Your Garage?

High humidity levels in a garage can cause mildew to grow, rusting, and corrosion at an alarming rate. Specifically, high humidity can cause the following issues:

• Paint can crack from moisture that settles on it
• The metal parts on your car can be affected by high humidity causing them to wear out
• Snow and rain can cause a sogginess that can damage tires

Where Can You Remove Moisture from Your Garage?

Here are a few possible sources of moisture that can occur in your garage:
• Pipeline and drains leakage can cause a lot of dampness
• Appliances can cause moisture and heat issues in your garage if they are run regularly and lack ventilation
• Melting snow and rainwater condensation

Why Should You Use A Garage Dehumidifier?

Usually, most people will not know they are having a humidity problem until they start to see problems. A lot of things can be affected by removing moisture that is in the air including:
• A good dehumidifier helps to keep the air fresh in your garage
• Dehumidifies will help you maintain your vehicles and keep them in shape
• Metal parts will no longer suffer from rust and moisture exposure
• Mildew and mold find high humidity environments the perfect breeding ground, which can affect your family’s health or anyone that works in the garage on a daily basis

Tips When Choosing a Garage Dehumidifier


You will be able to choose from two types of dehumidifiers that are suitable for use in the garage. The first type is a desiccant dehumidifier that is a great option thanks to their use of desiccant wheels when extracting moisture from the air. Operating quietly, these are nice dehumidifiers for those that prefer less noise. They are also perfect for use in garages since they do not use coils that could freeze if the temperature in the garage reaches a low level.

The second type is called a compressor dehumidifier, which is really a good choice for a large garage space. Typically, more powerful when it comes to pulling moisture out of the air, these dehumidifiers also conserve energy thanks to their speed and efficiency when they operate.

Since both dehumidifiers work well in a garage setting, you should choose the one that fits your needs and goals best.


You are probably asking yourself, how big of a dehumidifier do I need? The first thing you need to do is measure the space you will be using it in. With a large garage, you will probably have more several dampness than a small area, so you will need a dehumidifier with a larger capacity. Typically, a dehumidifier that has a capacity of 70 pints of water or more is a good choice for a large space that has a bigger problem with humidity.


Anything that you have running all day needs to be a safe machine to use. Always look for a dehumidifier that comes with an automatic shut off that will stop it once it reaches its full capacity. The best choice is a dehumidifier that will connect to a drain hose, which will allow the water to drain continuously. This will save you from having to empty the water tank constantly. Otherwise, look for a dehumidifier that has an alert when the tank becomes full and that comes with an automatic restart feature in the event of a power outage.


Depending on your preferences, you will probably want to check reviews to see how noisy the dehumidifier you want to buy is. This will help you find one that isn’t very noisy, so you won’t’ be distracted by the unit running all day long.

Low-temperature Settings

Most garages are not heated, so they can reach some pretty low temperatures in the winter causing the dehumidifier to not work correctly. And, if you have chosen a dehumidifier with a compressor, you will also have to worry about the coils freezing. Look for a dehumidifier that has an anti-frost feature that will let it operate well in a garage when cold weather sets in.

Humidity Levels

Another consideration is the humidity level in your garage. If you have a particularly high level of humidity, you will need to avoid those devices that do not work as efficiently when removing a large amount of moisture from the air.


Typically, you will see one of two types of drainage systems on a dehumidifier. Both remove water from the air, but they use different approaches. One uses a tank where it collects water that is then manually taken away to be drained. The second type of drainage system uses a drain hose that empties the water continuously empties into a drain.

 When choosing which drainage system is best for your garage to make sure to consider if you have an available drain or will be able to constantly empty the tank before making a choice.


What’s the best place for your dehumidifier?

You need to find a location leaving six inches between any obstructions and intake on the dehumidifier. Here are a few other key guidelines that will allow for the best distribution of dry air:

• Place the unit close to the return air vent as you run the AC system in your home. This allows for better distribution of dry air through your entire home.
• If you are placing it in a large space, but the dehumidifier in a central location.
• If necessary, you can use a fan to move the air between the rooms better

What is the best fan speed to use?

Typically, a dehumidifier will have both a high and low fan speed. You will want to use the low fan when running the dehumidifier allowing the machine to be quiet for most of the time and then use the high speed when you need to quickly remove moisture.

Will the fan in the dehumidifier run after it reaches the desired humidity level?
This will depend on the model that you buy. Some units will turn off when the reach the humidity level that you prefer. Others can run intermittently when the sample the air to see if the humidity is still at the desired level although they won’t run all the time like it does when it is actively dehumidifying. Keep in mind that it only draws a little energy when the dehumidifier’s fan is running.

Do you need to replace the filter?

Usually, a dehumidifier includes an air filter. It is the filter’s job to filter large particles out of the air and keep them from getting inside the unit where it can damage the evaporator or compressor. You do not need to replace the filter, but you will need to vacuum or rinse it periodically, especially if you are running it all day. You can do this less often if you are not running the machine all the time.

Can I use an extension cord?

Typically, a dehumidifier will have a six-foot-long cord that comes with it. It is not advised to use an extension cord at any time by the manufacturer. This may prevent you from placing farther than six feet from an outlet, so you will need to plan accordingly.

After the power goes out, will the dehumidifier restart automatically?
In most cases, the dehumidifier will restart automatically at the previously saved settings.

Should I buy a hygrometer for my dehumidifier?

A built-in hygrometer is found in almost every dehumidifier on the market today. With this feature, it will display on the control panel what the ambient humidity is in the room. While some hygrometers are better than others, most will be able to give you a decent reading for most uses.

However, if you are using your dehumidifier in a really large space, you may want to consider having a separate hygrometer. In this instance, you will want the hygrometer to help determine the humidity level of various locations away from where the dehumidifier sits.

What is the lowest humidity setting for a dehumidifier?

Typically, most dehumidifiers will be able to get the relative humidity of a room down to around 35%. Most dehumidifiers will have a panel where you can choose your preferred humidity level, and it usually goes down to only 35% RH. Most dehumidifiers should be able to accomplish this humidity level without a problem.

If my dehumidifier drains with a hose, will it make a difference in what capacity the dehumidifier has?

Yes, the capacity still makes a difference since the capacity is not referring to the water collection bucket capacity but the amount of water that the machine can pull out of the air during a 24-hour period. If you have a machine with a 70-pint capacity, that means it removes 70-pints of water from the air over 24 hours no matter if it is draining into a drain or bucket. Typically, a dehumidifier will have a water collection bucket capacity that is smaller than what the machine’s overall capacity is.

Now you know that having a dehumidifier in your garage is pretty much a necessity. Keeping all your belongings in your garage safe from too much humidity and mold growth, a dehumidifier can also help create a better breathing environment for you and your family. Always consider the size of your garage and your humidity levels before you make your final decision so you can find the best dehumidifier garage for your needs.
