The Best Garage Dehumidifiers of 2022 Reviewed

How to choose the best dehumidifier for your garage

If your garage is damp, musty, or feels clammy even after cleaning it, there’s a good chance that there’s excess moisture in the air. This means mold and mildew will start to grow. And if you’re storing things like guitars or electronics in the garage—or even family heirlooms—they could also be damaged by humidity.

A garage dehumidifier is a great way to solve this problem. The best garage dehumidifiers will remove excess moisture from the air (rather than just masking it), leaving behind a dry, comfortable space that’s safe to work in or store items.

We’ve rounded up some of the best garage dehumidifiers on the market right now. They include everything from simple-to-use dehumidifiers that manually drain to nifty, smart garage dehumidifiers that automatically regulate the level of humidity. We’ll go over what we like and don’t like about each one, along with some buying tips.

What size dehumidifier for garage?

Garage dehumidifiers come in many sizes and capacities, so you should choose one matches your specific space and needs. A garage dehumidifier that’s too large for your space will waste energy and run up your electricity bill, but a unit that’s too small won’t do its job properly.

The first thing you need to do is determine how large and damp your garage is. You can do this by measuring the square footage of your garage. Also, consider the humidity of your space (use a hygrometer to measure the level of moisture build-up in your garage). If your garage is moderately damp, a dehumidifier with 25-40 pints of moisture removal capacity per day will do the trick. For extremely damp areas, you want a heavy-duty dehumidifier for garage that can handle 40-70 pints per day. The higher the capacity, the more moisture a garage dehumidifier will remove from a room. If you’re still not sure what size dehumidifier for garage to get, use our handy chart below to help guide you toward a model that suits your needs.

Is there a difference between a regular home dehumidifier and a garage dehumidifier?

While many home dehumidifiers can be used for garages, garage-specific dehumidifiers like Ivation will give you the best results as they are designed specifically to remove extra humidity from your garage, allowing you to store your items without worrying about mold or mildew. The best garage dehumidifiers typically have a larger capacity than regular home dehumidifiers and are often made of rugged plastic and metal construction.

What are the best garage dehumidifier brands?

When shopping for a new garage dehumidifier, you want more than just convenience and reliability – you’re also looking for durability. Some of the best garage dehumidifier brands include Ivation, hOmeLabs, Frigidaire, Honeywell, Wayne, Danby, and Frigidaire. However, you should consider features that are important to your needs, including the size of the garage, garage humidity levels, drainage system, and energy-saving capabilities.

What is the best low-energy garage dehumidifier?

Low energy dehumidifiers may use less power, but they might not be as effective in removing moisture. To get maximum efficiency out of any unit, find an Energy Star garage dehumidifier.

What is the best type of garage dehumidifier? Desiccant dehumidifiers vs refrigerant dehumidifiers.

Desiccant garage dehumidifiers are the best option for low-temperature or unheated garages. They are most effective at around 5°C (41°F) but work just as well up to 30°C (86°F) Also, they require no defrosting time, and they have better results in a shorter time. But they cost more than refrigerant garage dehumidifiers. On the other hand, refrigerant dehumidifiers are more effective in warmer spaces and are most effective above 20°C (68°F). Their effectiveness falls quickly at lower temperatures though. Additionally, the colder the temperature, the more time the machine will need to spend in “defrost” mode. This wastes energy and the dehumidifier can’t remove moisture when in this mode. Overall, desiccant garage dehumidifiers do a better job in colder temperatures whereas refrigerant garage dehumidifiers models are more effective in warmer conditions.

Where to place a garage dehumidifier?

A garage dehumidifier is a great way to keep your space cool and dry, but where do you put it? If you have a small garage dehumidifier, you can place it in the center of the space with everything else around it. The ideal location for larger garage dehumidifiers is near walls, outlets, and a drain. Just make sure there’s enough room around it so air can circulate.

What is the best dehumidifier for a large garage?

If you are dehumidifying a garage measuring 3000+ sq ft, you’ll probably need a more powerful garage dehumidifier. One of the best and most popular efficient dehumidifiers for large garages is hOmeLabs dehumidifier model – a good choice for large spaces and garages measuring 2500sq.ft plus.

What’s the best kind of dehumidifier for a garage without drainage?

If you don’t have a drain in your garage, you will want to buy a dehumidifier with a water tank. You will have to manually empty the tank once full, but if you have a drain, go with a garage dehumidifier with a drain hose that can direct the water straight into it.

What is the best quiet dehumidifier for a garage workshop?

If you work in your garage for any extended periods, the noise made by some garage dehumidifiers can be quite jarring. You’ll want the quietest dehumidifier for garage workshop spaces and the Ivation dehumidifier brand is a good place to start.

Draining Options: Tank or drain garage dehumidifier?

When you’re looking for a dehumidifier for garage, one of the most important things to consider is what your drain options are. There are two main ways that a dehumidifier can drain: into a tank or directly into your drainage system. Garage humidifiers with tanks collect water in an included tank until it’s manually emptied. If you don’t empty the tank regularly enough, you risk an overflow. With direct-draining garage dehumidifiers, though, the water automatically drains into a sink or drainage system. For most of these direct-draining units, water runs down a hose into floor-level drainage (if your space doesn’t have floor-level drainage, buy the best garage dehumidifier with pump so you can drain water into a basement sink).

Energy Efficiency

Typically, dehumidifiers for garages run 24/7, which is why it’s important to find an is energy-efficient dehumidifier so you can save on your electricity bills. Just how good a garage dehumidifier is depends on its performance against the energy used – a good garage dehumidifier will extract the most moisture from the air using the least amount of energy – and od it faster than other dehumidifiers on the market.

So, when you’re looking for the best garage dehumidifier, consider going for an Energy Star-certified model. These are the most energy-efficient dehumidifiers on the market compared to other products.
