The garage is a wonderful place to store everything from tools to garden supplies, and everything in between.

However, they can also be extremely humid, which provides the perfect environment for mold and mildew to thrive.

To prevent the build up of mold and other humidity-related issues, it can be a good idea to invest in a dehumidifier for your garage.

This should take care of any existing excess humidifier in the air, and regulate it going forward so you don’t have to worry about rot, rust, or mold.

h0meLabs 3,000 Square Feet Dehumidifier (👑 Best of the Best)

In our view, the best dehumidifier for a garage is this 3,000 square foot device from h0meLabs.

While we’ll be reviewing the 3,000 square feet model, h0meLabs also offers 1,500 and 4,500 square feet devices, so you can pick the dehumidifier which works best for the size of your garage. This model can remove up to 35 pints of water from the air per day, which makes it perfect for a moisture-retaining garage or even a basement or cellar. It’s Energy Star certified too, which means it is energy-efficient and should save you money on your energy bills. Plus there are wheels fitted to the device, which makes it easy to roll around if you need to reposition the dehumidifier for any reason.

What’s great about this dehumidifier is you can adjust the moisture level to suit your garage. If you’re having particularly bad issues with humidity in the garage with visible signs of mold or rot then you can crank it up to high, or you can have it run at a lower setting as a precautionary measure to keep the air free from excessive moisture. Plus, this dehumidifier can run continuously for a whole day, up to 24 hours. You don’t have to worry about being there to switch it off the moment the tank is full though, since the handy automatic shut off feature ensures the device powers done once it has finished its cycle.

There are several other features which make this dehumidifier stand out from the rest, including a touch control panel, auto restart, and a turbo mode. These features combined with the custom humidity setting which lets you choose a level between 35% and 85%, provide the most comprehensive user experience.

Pro Breeze Electric Mini Dehumidifier (🥈 Runner Up)

Our runner up pick for the best garage dehumidifier is the Pro Breeze electric mini dehumidifier.

For a compact unit, this mini dehumidifier from Pro Breeze does an excellent job for most rooms, including high humidity ones like basements and garages. Perhaps best of all is its small size, since you can easily tuck the device way in a corner so it doesn’t add yet more clutter to a space that tends to be full of things. If you already have an overwhelmingly full garage, then the last thing you want is a big and bulky dehumidifier taking up yet more space, since it will make getting in and out a hassle. The unit weighs just 5.08 lbs, which makes it effortless to move from one room to another, in case you want to regulate the moisture in the air of multiple spaces around the house.

Just because it’s small, it doesn’t mean this unit isn’t capable of coming up with the goods. With the Pro Breeze you can remove up to 18oz of water a day with a 52oz water tank capacity, which makes it perfect for rooms around 250 square feet. To give you an idea of what that means in more concrete terms, the average garage is somewhere in the region of 162 square feet to 380 square feet. So this unit should be suitable for all but the largest of garage spaces. This dehumidifier works best in temperatures of 59-86 fahrenheit, which should be perfectly suitable for damp spaces.

As for features and functionality, the Pro Breeze uses advanced thermoelectric peltier technology, which means that it is both very energy efficient but also operates almost silently. While this isn’t completely necessary for a room like the garage, it’s certainly nice not to hear a constant humming sound in the distance. This dehumidifier has an automatic shut off feature too, so you won;t have to get up from the sofa to go and switch it off after it has finished collecting water for the day. This isn’t only convenient, but can also help to preserve the dehumidifier and prevent it from burning out.


  •  Covers up to 250 square feet
  •  Compact design
  •  Automatic shut off
  •  Ultra quiet operation
  •  Uses thermoelectric peltier cooling technology
  •  Removes 18oz moisture per day
  •  52oz capacity water tank
[amazon box=”B01HXVUT7C” title=”Pro Breeze Electric Mini Dehumidifier” description=”If you’re looking for convenience without sacrificing too much in the way of performance, then the Pro Breeze mini dehumidifier is a fantastic option. It’s small enough to be portable and quiet while in operation, but also delivers great results by lowering the humidity level in particularly damp rooms like the garage or basement.”]

SEAVON Electric Dehumidifier (💰 Best on a Budget)

If you haven’t got a lot of cash to spare but you need to address the humidity level in your garage, then the SEAVON electric dehumidifier could be your best option.

This dehumidifier is available at around half the price of the Pro Breeze device, and still provides outstanding performance. The caveat is that it’s only suitable for spaces up to 205 square feet, so it’s best suited to smaller garages. With that being said, it does an excellent job of taking the moisture out of the air, with a 16oz tank capacity that’s capable of extracting 10oz every day.

This device has a lot in common with the Pro Breeze mini dehumidifier, but weighs even less than that device. At just 2.4lbs, this is an incredibly lightweight unit, which makes it easy to carry to different rooms around the house. It also means that even if you have a large garage and don’t think this dehumidifier can cover all of the space, you can simply move it from one side of the room to the other for great results. Like the Pro Breeze, the SEAVON device features an automatic shut off function when the tank is full of water, and the LED light will turn red to indicate it’s time to drain out the tank.

It is also a very quiet dehumidifier, so if you feel like you’ve got the moisture level in the garage under control, you can bring it into the bedroom to help you sleep at night. It’s also useful for staying on top of mold growth, since you can take the dehumidifier to the source of the issue whichever room that may be.

The SEAVON dehumidifier comes with a 2 year warranty, and the company is committed to providing unlimited customer service and tech support. The brand promises to respond to any queries within a single working day, which should put your mind at ease in the unlikely scenario that something goes wrong with the device.

Ultimate Guide

Buying a dehumidifier isn’t a standard investment.

It’s more than likely that you aren’t fully familiar with everything that goes into making a dehumidifier great, so we’ve put together this guide to help you make an informed decision when the time comes.


By far the most important factor to consider, even before you start looking at dehumidifiers, is the size of your garage.

The average garage can be anywhere between 180 and 380 square feet, and it’s important that you know the exact measurements of yours.

To estimate the square feet of your garage, simply measure the length and width of the room, and then multiply the 2 numbers to get the total square footage. It’s best to measure in feet if possible since this will simplify the process, but if you can’t do that, you’ll have to convert the numbers you’ve taken into feet before you multiply them together.

Now that you know the square footage of your garage, you’re in a much better position to make the right decision as to what dehumidifier is best.

The coverage of any dehumidifier will be mentioned in the product description page on Amazon, so be sure to check that the numbers add up.

You don’t have to get a dehumidifier that matches the square footage of your garage exactly though, and in some cases one with more or less coverage than you think is necessary can be suitable.

If the dehumidifier covers less square feet than the space of your garage, like could be the case with the small SEAVON unit we cover, then it can still have its uses. You can use it for the worst affected areas of the garage and then move it around, or you can have it as a dehumidifier that you use in all rooms of the house.

Likewise, if the dehumidifier covers more square feet, it can also be suitable, since it will likely reduce moisture in the air more efficiently and take longer to fill up.


The efficiency of a dehumidifier is another important factor, and can be divided up into 2 parts.

There’s the capacity of the water tank, and the rate of moisture extraction.

Tank Capacity

The tank capacity is hugely important, since it will determine how often you will need to empty out the water that’s been collected.

If you’re buying a dehumidifier to leave running continuously in the garage while you go about your day, and you don’t want it to be a distraction that you have to deal with regularly, then you need one with a large tank capacity.

Some dehumidifiers will state how long they can run for, which is as good as indicating the capacity of the tank, since it tells you how long you can expect to wait before you need to empty out the water.

So this is definitely something to consider depending on your preferences. Bear in mind that a large tank will be heavier, so if you want something that’s easy to empty out and refill then a small unit may be the best option.

Moisture Extraction

The main factor which determines a dehumidifier’s efficiency is the rate at which it extracts moisture from the air.

The more water it can extract from the air (which is usually given as an hourly figure), the more effectively it will tackle the humidity problem in your garage.

If you are already starting to see signs of mold or have had troubles in the past, then a device with a high rate of moisture extraction is highly advisable.


Here are some of the most common and useful features to look out for when selecting the perfect dehumidifier for your needs.

Automatic Shut Off

Automatic shut off is a very convenient feature for any device to have, since it reduces the chance of the dehumidifier burning out by trying to run even when the tank is full.

It also means you don’t have to rush to empty out the tank as soon as it’s done filling up, you simply change it out whenever you see the LED light turn red.

Quiet Operation

Usually a product of the technology a dehumidifier uses for moisture extraction, quiet operation can be a great feature.

If you’d prefer not to have a constant loud humming sound coming from the garage, then you’re best served by getting a device like the Pro Breeze which runs almost silently.

Continuous Drain

If you have access to a drainage system which you can connect a water tank up to, then continuous drain becomes a must-have feature for any dehumidifier you look at.

Rather than having to empty out the water tank by yourself, which can get tiresome very quickly, and require constant maintenance, the continuous drain feature provides a convenient alternative.

This feature will largely remove the need for regular maintenance, since the water tank will regularly be emptied out into the drainage system you have it hooked up to.

This is ideal for taking care of a garage humidity problem without needing to be hands-on with it.

Frequently Asked Questions About Garage Dehumidifiers

What size dehumidifier do I need for my garage?

In order to determine which size dehumidifier you need for your garage, you will need to know the square footage of the room.

Once you have that figure handy, look for a dehumidifier that has enough storage capacity for the square footage.

A 30-pint unit for example will be sufficient for a square footage of up to 1,500, while a 50-pint unit will work for garages between 1,500-1,700 square feet, and a 70-pint unit will deal with any garage over 2,500 square feet.

Yes, a dehumidifier is a very useful device to have for your garage.

The main reason you should consider investing in a dehumidifier is to deal with any humidity-related issues you might have in the garage, just as the growth of mold.

Having a dehumidifier in the garage will regulate the moisture level in the air, and prevent your tools from rusting, mold from developing, and any wood from rotting.
