While it may seem harmless at first, water in the form of excess moisture in the air greatly accelerates the rusting process in metal. High humidity also attracts all sorts of pests, mold, and mildew to your garage. If it doubles as a storage space or a workshop, then it becomes imperative that you invest in a high-quality dehumidifier for garages. We’ll discuss two options here, one that’s best for large garages and basements and the other- for more compact spaces.

The Best Dehumidifier For Garage

1. hOmeLabs HME020031N 9 Gallon (70 Pint) Dehumidifier For a Garage

hOmelabs is a relative newcomer to the dehumidifiers for the garage industry, having come into existence in 2014. Even so, their portable, 70-pint hOme garage dehumidifier gives other established brands a run for their money. This model is perfect for any large room, basement, or garage where you want the humidity level reduced.

This best garage dehumidifier not only saves your home from the threat of airborne allergens, mold, and mildew —it also saves you money. It is incredibly energy efficient, meaning you’re easing the burden on the environment. It costs less to run these dehumidifiers for garages than others on the market.

The hOme Dehumidifier is fairly straightforward to use: you just set your ideal moisture levels and let it run its continuous 24-hour cycle until it is full. At that point, it will automatically turn off until you drain the unit. For convenience, the manufacturer included a drain hose outlet so you can attach a hose for continuous draining if you prefer continuous operation. The built-in dehumidifier pump reduces odors as well.

What sets the hOme Dehumidifier apart is the turbo mode that increases the fan speed from Normal Air of 165 CFM (cubic feet/minute) to High Air of 188 CFM to maximize moisture removal and odor reduction in your house.

Pros

• Energy Star certified
• 70-pint capacity
• Large enough to fight humidity in a garage, basement, or any large area
• 24-hour continuous cycle with an outlet for the drain hose
• Set your ideal levels for 24 hours at a time
• Built-in pump
• Auto-turn off
• Turbo mode

Cons

• Small water holding (12.8 pints) means you’ll have to drain it over six times a day in high-humidity environments
• It does not work in the same room as an evaporative cooler

2. Frigidaire FFAD7033R1 70-Pint ENERGY STAR Certified – Garage Dehumidifier

The first entry in our best list of garage dehumidifiers comes from Frigidaire, a renowned consumer appliance brand that has been around for over a century. The craftsmanship and quality in their work come through once again in the FFAD7033R1 Dehumidifiers, with its high capacity of 70 pints of air per day. These large-capacity dehumidifiers are an ideal choice for a garage and a large basement.

This 70-pint dehumidifier works round the clock, monitoring humidity levels and protecting your home from mildew and mold by drying out the air it processes. It also helps eliminate airborne bacteria that make breathing difficult, providing your home with cleaner and higher-quality air.

The most prominent part of the Frigidaire 70-pint dehumidifier for the garage is its Ready-Select electronic settings controls with a digital display readout that allows you to see the current humidity level in your household. The Effortless Humidity Control lets you adjust the moisture level with its straightforward controls. Also, these dehumidifiers have a 24-hour on/off timer and control lock, giving you complete control of when and how it operates.

This Frigidaire unit shuts off automatically when the water tank is almost complete. The FFAD7033R1 Dehumidifier’s patented SpaceWise portable design includes a top handle, integrated side handles, and caster wheels, making it incredibly easy to battle humidity from one room to another.

3. Pro Breeze FBA_PB-03-US Mini 2200 Cubic Feet (250 sq ft) Dehumidifier For Garage

If you have a fairly small garage, you need not buy a 50-pint garage dehumidifier product. This is perfect for when it gets humid in small spaces. This compact unit, with a 2000ml (68 oz) water tank, should get the job done. The Pro Breeze Electric is perfect for your needs if you have a space of around 220 sq ft.

This dehumidifier for garages removes up to 18 ounces of water per day with a 52-ounce capacity. That means you can leave it to trap humidity for almost three days and let it protect your vehicles from rust, mold, and pests without draining the unit. The auto-shutoff will power down the dehumidifier if you’re away from home for longer than three days and cannot drain it.

The Built-in Thermo-Electric Cooling Technology, which uses the Peltier effect, allows the dehumidifier to run without a compressor. This provides whisper-quiet operation if you want to bring it to other sections of the house, such as the bedroom or the bathroom. It is also compact, portable, and lightweight if you want to bring it with you for your RV or caravan trip.

The best operating temperature for this portable dehumidifier is between 59 and 86°F, perfect for a small high-humidity garage or workshop with small square footage.

Pros:

• Compact, portable, and lightweight
• Removes 18 ounces of moisture from the air per 24 hour
• Auto-shutoff
• Features Peltier technology for whisper operation
• Affordable

• This unit does not work below temperatures of 41°F

• No built-in pump

4. SEAVON Electric – Moisture Removal

The next dehumidifier unit on our best list for the garage comes from SEAVON. This compact device with a 500 ml capacity processes approximately 250 ml of air daily and works best in small spaces. The dehumidifier’s optimal room size is 180 square feet.

The SEAVON Electric saves a lot of space, and its size makes it incredibly useful. You can move this unit around the house if needed, and you can bring it to your caravan or RV.

One of the best features of this dehumidifier for the garage is its auto-shutoff function the moment it fills up with water. Its LED light turns red to let you know it needs emptying. You can easily remove the tank, empty it, and put it back without problems.

The Built-in Thermo-Electric Cooling technology on this unit allows it to dehumidify without a compressor, meaning you get but a whisper of sound as it works quietly in the background. That makes it perfect for small apartments and even in a bedroom for a good night’s rest.

While the SEAVON Electric Mini Dehumidifier unit works well for its size, it’s not the best choice for all environments. Its optimal operating temperature is between 59 and 86oF, and it will not work at temperatures below 41oF

The KSTAD50B features electronic controls with an LED display for easy use. The LED display also shows a full-tank alert to let you know if it’s time to empty, which you can also see via its transparent water level indicator. You don’t have to worry about the dehumidifier spilling, either, as it also has an automatic shutoff.

We consider the KSTAD50B one of the best dehumidifiers for the garage because it is Energy Star compliant, meaning it saves on energy, costing both you and the environment less to run compared to other dehumidifiers on the market. It also comes with an easy-clean dust filter, meaning you don’t have to keep replacing it. The clean-filter alert will notify you when it’s time to wash that filter to keep your unit from running on overdrive compensation.

Pros:

• Easy-to-use electronic controls and LED display
• Filters 50 pints per day in the space of up to 3,000 square feet
• Drainage hose outlet for continuous drain operation

• The tank has to be emptied immediately – you can’t set it down because the bottom is not flat

Temperature and Humidity Considerations for Garage Dehumidifiers

A dehumidifier for a garage with all the bells and whistles might not be the best for your needs. Choosing the best dehumidifier for your garage means you have to consider temperature. Like most garages, yours isn’t heated, so the temperature is something that you have to consider in your search for a dehumidifier product. If you check the temperature of your garage and it never goes below 60°F, then this isn’t a concern. However, if your garage gets colder, you have to ensure that the dehumidifier for the garage you’re purchasing remains efficient at the proper temperature.

Suppose you know that your garage gets close to freezing temperatures. In that case, we recommend you purchase a dehumidifier with an auto-defrost humidistat like the KSTAD50B, which will remove frost build-up on the device’s evaporator coils. Without this feature, the compressor on your unit won’t turn on and won’t reduce moisture in the air.
