Garages are prone to mold, mildew, and rust more than almost any room in your home. Dark spaces and moisture combine to create the perfect environment for bacterial growth, but dehumidifiers can tackle the problem. There are dozens of choices, but only a handful of them are worth using in your home.

The best dehumidifier for a garage is the CLEVAST 1,500 Sq. Ft. Energy Star Dehumidifier. It has a 0.8-gallon tank with a drain hose to pour water out of the tank effortlessly. There’s a 24-hour timer you can set, and it’s listed as an energy-efficient model by Energy Star. It’s also ultra-quiet.

Throughout this article, you’ll also learn the following information about the best dehumidifiers for garages:

  • Three noteworthy features to look for in your next garage dehumidifier.
  • Details about the best dehumidifiers for your garage, regardless of its size.
  • Low-noise, high-tech, and hands-free designs to consider

What To Look for When Getting a Dehumidifier for Your Garage

You can’t choose a random dehumidifier for your garage, or you’ll end up with one of many problems. For example, getting a massive dehumidifier for a small space is a waste of money and space. On the other hand, a small unit won’t get the job done quickly enough.

In my research, I’ve come across three factors that are found in every high-end garage dehumidifier:

  1. They need to have a tank that’s big enough to handle the space. A bigger tank will store more water, increasing the time between emptying it. If you have a large garage and a small water tank, you’ll have to empty it daily. The adequate tank size will let you drain it every three or more days.
  2. Square footage is equally as important as the tank size. Your dehumidifier should have a powerful fan to pull water from the air. If it’s not strong enough, you won’t notice much of a difference. Fortunately, all of the dehumidifiers on the list below their square footage listed. Measure your garage and choose the one that fits.
  3. Maintenance is another essential component of the process. How often do you have to empty the water tank? Is there a draining hose? How long is the power cable? There are several considerations involved in the process. Make sure you’re not sacrificing functionality and maintenance to get a cheaper model.

Let’s break down all three traits below.

Tank Size

The tank size is crucial when you’re choosing a dehumidifier for any space in your house, especially the garage. As mentioned earlier on the page, garages are a breeding ground for bacteria, mold, mildew, rust, and pests. By removing water with a dehumidifier, you’ll eliminate all of the problems.

So, how do you know what tank size you should choose?

  • The tank size is based on how much water it consumes daily. If your dehumidifier pulls one gallon of moisture per day and the tank is half of a gallon, you’ll have to empty it twice each day. The goal is to get a dehumidifier that needs to be emptied every two to three days or more.
  • Consider your garage’s square footage. We’ll dive into the details of measurements and choosing the best size in the next section, but it’s essential to compare the tank size to the square footage and water consumption. Failure to do so will increase daily maintenance. As you can see, all three traits relate to one another.
  • According to Bob Vila, you should get a tank with 10 pints of space per 500 square feet. For example, if you have a 1,000 square foot garage, get a dehumidifier with a tank that’s at least 20 pints. This number may vary depending on your garage’s ambient humidity.

Square Footage

Square footage is the clearest indicator of the dehumidifier you should get for your garage. I’ve made a chart detailing the tank size you’ll need for the provided square footage. Keep in mind the table is made for extremely damp environments, so the calculations are slightly higher than the 10-pint per 500 sq. ft. suggestion.

Square FootageDamp GaragesExtremely Damp Garages
500 sq. ft.30 pints30 pints
1,000 sq. ft.30 pints50 pints
1,500 sq. ft.50 pints70 pints

If you live in an extremely humid area, you might need a bigger tank. Those who live in dry environments could get away with anywhere between 10 to 20 pints, as mentioned in my example in the previous section. Your tank size and square footage depending on the ambient humidity.

One way to test the humidity to choose the best dehumidifier for your garage is to get a hygrometer. Hygrometers test the air’s humidity, so you can use the information to choose the correct model. They also allow you to see how well your dehumidifier is working. Dehumidifier Buyer’s Guide explains many top-notch units will cut the humidity down to 30% to 40%.

Maintenance

Although it’s the final piece of the puzzle, maintenance is a significant part of the process. It determines how often you’ll have to repair, drain, and operate the dehumidifier. You can save money by getting an inexpensive unit, but you’ll have to maintain it much more often than high-quality models.

Maintenance involves draining and fixing parts. Many dehumidifiers come with draining hoses for your convenience. Stretch the hose outside or into a garbage can, then dump the water elsewhere. You can reduce maintenance by getting a bigger tank and a lengthy drain hose. Remember, large garages require much more dehumidifier maintenance. Humidity directly impacts your efforts, too.
