8 Best Dehumidifier for Garage – Reviews & Buying Guide In 2022

Author: | Latest Update On:

A dehumidifier is a must-have appliance for every garage, but not all dehumidifiers are created equal. The best dehumidifier for your garage should be one that can handle the space well and won’t break down after just a few uses.

We’ve put together a few reviews of the best models on the market to make things easier for you. We’ve considered the right size of the machines, how easy they are to maintain, alongside having the right features.

Most dehumidifiers are capable of keeping large garage humidity within the right levels, while all of them are perfect for small garages. If you’re suffering with high level of humidity in the garage, let’s give you the right protection.

You’ll be able to equip the garage with the rig that keeps the inside out of mold and mildew.

Can You Use a Dehumidifier in a Garage?

You should run a dehumidifier in the garage to avoid growth of mold, health issues and to prevent structural damages. The best way to do this is to run the unit at least 12-18 hours per day. This is crucial, especially if you live in a humid area.

Pro Tip: Make sure that your dehumidifier has an automatic shut off feature so that it can run for as long as needed without constantly worrying about turning it back on each time you leave. This will also save electricity, which means less money spent.

What Kind of Dehumidifier Do You Need for the Garage?

The size of the dehumidifier depends on the size of your garage. A 70-pint size is enough for large garages, while 20 being enough for personal ones. It will be sufficient to keep mildew from forming in a small area.

If you’re willing to spend more money, there are models with bells and whistles like humidistats. These allow for remote monitoring, as well as heating coils at the top for those who live in very cold climates (some include sensors that detect high humidity levels).

You just might have to buy a size up, depending on how much area you need to dehumidify. If your garage size is too large for the size of the unit, it may take some time before all moisture has been collected and evaporated from the air.

Will a Dehumidifier Make a Garage Feel Cooler?

A dehumidifier is also beneficial because it reduces relative humidity levels in a space by up to 50%. This not only leaves the air feeling cooler, but fresher as well. For this reason, you’ll find that your garage feels an average of five degrees cooler after running for just 24 hours. Cooling down with a dehumidifier also helps produce surface-level ozone so freshness lasts much longer than might have otherwise been expected.

Factors To Consider When Buying a Dehumidifier for Garage

Some factors to consider when buying a dehumidifier for your garage include the following:

Dehumidifier for Garage

Pints Per Day

The pints per day for a dehumidifier is the amount of moisture it can extract from the air in a day (24 hours). For a garage, the PPD typically ranges between 15-35 pints per day. For most garages, you will want to buy a dehumidifier with at least 25 PPD. The higher PPD rating the better because it means that your dehumidifier can extract more moisture in one day than one rated lower.

If you have an especially humid area like Florida or Arizona, then there are some other considerations such as getting a desiccant model for cold climates and using refrigerated coils if it’s too hot outside year-round (even during winter).

The PPD is also important when deciding how large of a unit you need to get based on square footage size; this is often listed as the CFM which stands for Cubic Feet per Minute.


The coverage of your dehumidifier is the measurement of how much space your dehumidifier can cover. Coverage is determined by the size and number of air vents on the machine as well as its capacity. Larger, higher-capacity dehumidifiers have more coverage than smaller ones with lower capacities do.

Drain Options

Your dehumidifier will need to be connected to a drain. Drain methods vary depending on the type of dehumidifier you have and your requirements, but there are two main options:

  • Ducting Drain (Easiest)
  • Air Drain/Drain Pan Combo (Best for Large Areas & Continuous Use)

Your decision will depend largely on the size of the area that needs dehumidifying as well as how often it is in use. The ducted option requires less work, because all you need to do is connect the hose from your unit into an existing drainage system or open window.

On the other hand, if you live in a warmer climate with more humidity or want continuous drainage option without needing to empty out water buckets every day, then the air drain/drain pan combo will work best.

Number of Modes

The number of modes in your dehumidifier matter. You need to know the difference between how much water that you want it to remove from your garage and whether it will be able-to do so with different modes. Choose modes like continuous operation if you’re looking for something simple or auto mode for more advanced users who don’t mind checking in on their dehumidifier every day.

There are two main types of modes:

  • Continuous Operation (the machine runs until there is no longer enough humidity).
  • Auto Mode (auto-stop when set amount of moisture in the air is reached, then resuming when it changes).

The number one question people have is what type of climate they live in? If one lives in a dry climate such as Arizona where relative humidity levels can drop below 20% during the winter months, they will need a more powerful dehumidifier with the ability to operate in continuous mode.

A less dry climate, such as Florida where relative humidity levels are typically over 60% year-round, would only require use of an auto-mode with lower power consumption and quieter operation.

Frequently Asked Questions

Here are some common questions asked about dehumidifiers, especially the ones for garages:

What size dehumidifier do I need for my garage?

The size of the dehumidifier for your garage depends on the size of the garage. A 70-pint dehumidifier is usually big enough for most large garages, but even small dehumidifiers will make a difference.

Is it worth putting a dehumidifier in the garage?

The humidity from the garage will create a lot of discomfort and it may also cause mold to grow. In order to prevent mold, run a dehumidifier when the moist air in your garage gets thicker.

Can you put a dehumidifier in the garage?

Yes, it is a smart idea to put a dehumidifier in a garage as both garages and the areas around them are notoriously humid. Dehumidifiers will suck up the moisture from the air, leaving it cool and dry.

Why is my garage so humid?

Homes in high humidity climates will often experience condensation as well as lower temperatures. If you use devices that create heat in a cold garage without proper ventilation, excessive moisture will be created. Leaks in your garage roof can also lead to excess condensation.

Where is the best place to put a dehumidifier?

The best place for a dehumidifier is in the room you need it in. When determining where to place a dehumidifier, be sure to consider any dampness or moisture-related problems in the area.


Your dehumidifier is a very important investment, but it’s not only about picking out one that looks great or has features you really want. It also needs to be properly maintained and connected to a drainage system in order for it to be efficient.

The Vremi 22 Pint 1,500 Sq. Ft. Dehumidifier is the best dehumidifier you should go for in your garage. You’ll get it with auto mode, 1500 square feet of coverage and high level of energy efficiency. It makes one of the best dehumidifiers for the garage in winter given its effectiveness.
