Best dehumidifiers for garage reviews

Homelabs – best overall

Homelabs

Improve the air quality in your garage with the largest Homelabs dehumidifier for large rooms (up to 4,500 square feet) and very wet spaces.

Unlike the Vremi product with 22 pints moisture capacity, the Homelabs entry removes up to 50 pints of water per day, depending on the garage size and the moisture level. With the 1.6-gallon water tank capacity, you can not worry about frequent draining. Besides, a drain hose outlet is compatible with ⅝” garden hoses with internally threaded ends for continuous draining. But the hose is not included, so if you don’t have one in the household, you will have to purchase one.

The dehumidifier is heavy (40 pounds), but there are wheels and an in-built handle for easier transportation. It’s also simple to use. You just set the desired moisture level, let the unit run the full 24-hour cycle, and it will automatically shut off when the tank is full.

Mind that if you do not use the hose outlet and collect water in the tank only, there might be the risk of growing organisms over time. So make sure you clean the tank regularly to avoid the problem. The quality of the build is slightly flimsy, but it doesn’t affect the unit’s performance at all.

The Homelabs is the best dehumidifier for a garage that would help effectively fight the issue of excess humidity in your garage. It copes with extremely humid air even in large spaces and proves to work smoothly.

Key specs

  • Working area, sq. ft: 4500
  • Moisture removal, pints/day: 50
  • Water tank capacity, gallons: 1.6
  • Weight, lbs/kg: 40/18.1
  • Dimensions, inch/cm: 15.4 x 11 x 24.3/39.1 x 27.9 x 61.7

Vremi – budget

Vremi

The compact yet effective Vremi humidifier is a great choice for an average-sized garage with up to 1,500 square feet of space.

By extracting around 22 pints of water from the air per day, it is primarily suitable for the areas where the humidity deviations are not critical. In contrast to the powerful Homelabs dehumidifier, this one will consume less energy while remaining effective in medium to large garages.

The unit runs on a continuous 24-hour cycle, meaning it will automatically shut off when the 1-gallon tank is full. There is also an outlet for attaching the hose for continuous draining, but the hose doesn’t come with the dehumidifier. You might want to use a turbo mode, which boosts the fan speed to rapidly improve air quality.

The Vremi item is compact and portable. It weighs 33.1 pounds and features wheels and side handles for convenient relocation.

But the noise level the device produces when it runs is disturbing. It gets even louder in the Turbo mode. Mind that you can’t set your own humidity level in the Comfort mode. The device will run according to pre-specified settings, which cuts customization.

The Vremi is the best garage dehumidifier from the budget-friendly segment that maintains great performance. It is suitable for wet medium and large garages and will effortlessly keep the moisture in the air down while saving your costs.

Key specs

  • Working area, sq. ft: 1500
  • Moisture removal, pints/day: 22
  • Water tank capacity, gallons: 1
  • Weight, lbs/kg: 33.1/15
  • Dimensions, inch/cm: 16.1 x 10.4 x 19.9/40.9 x 26.4 x 19.9 x 50.5

  • 1-gallon tank capacity ensures 24 hours of continuous work
  • Hose outlet for continuous draining
  • Energy-efficient and compact.

Cons

  • Gets noisy, especially in the Turbo mode
  • No customization of the humidity level in the Comfort mode.

Waykar PD1201B – for commercial use

Waykar PD1201B

Bring the humidity down to the comfort level in the extremely large space with the Waykar PD1201B.

This dehumidifier provides an insane level of power and performance as it removes 296 pints of water, even in space up to 8,000 square feet. Similar to Homelabs dehumidifier, this item works in the continuous mode monitoring the air quality. But the Waykar PD1201B comes with a long hose for continuous draining.

The energy-efficient compressor and turbine wind guide system ensures low energy consumption as well as quick condensation and dehumidification. The automatic shut on/off feature will stop the unit when the humidity level reaches its norm, while the power outage auto-restart function will restart the item automatically when power becomes available.

Waykar PD1201B picture

The Waykar PD1201B works pretty well as far as draining and dehumidifying. However, it is not as effective as it normally is at cold temperatures. I also noticed minor design flaws. Don’t keep the device near a wall because of the backside air intake if you want it to work effectively. You won’t find a water tank in this model as well, so the only way to drain the water is to use a hose.

No doubt that this heavy-duty dehumidifier for a garage will make a huge difference in the air quality in your garage or other construction. It has advanced features like a 24-hour sensor as well as shut on/off, power outage auto-restart, and defrost features for ease of use.

Key specs

  • Working area, sq. ft: 8000
  • Moisture removal, pints/day: 296
  • Weight, lbs/kg: 112.4/51
  • Dimensions, inch/cm: 19.3 x 14.6 x 30.7/49 x 37 x 78

Pros

  • Suitable for extremely wet garages with up to 8,000 sq ft
  • Consumes 296 pints of water per day
  • Precise sensor for tracking the humidity level in real-time
  • Included hose for continuous draining.

Cons

  • Works at 60% capacity in cold weather
  • It can’t be placed at the wall due to the backside air intake
  • No water tank for collecting water.

Waykar PD253B

Waykar PD253B

The Waykar PD253B dehumidifier is a functional unit that allows reducing the excess air humidity in the garage around 4,500 square feet by reducing 70 pints of water per day.

Similar to Kesnos PD253D, the Waykar PD253B has a ring-shaped air supply design, meaning that the dehumidified air is delivered in all directions for faster results.

The reviewed model is 30 pounds and has ergonomic wheels and handles for moving it around easier. The 1.18-gallon water tank collects water, while the included drain hose allows continuous drainage. There is an in-built 24-hour timer to shut off the device when the tank is full, and the smart sensors will adjust the operational mode based on the air quality. The LED display allows quick and easy configuration. The auto defrost function won’t let the unit freeze, even when the temperature goes down.

Waykar PD253B picture></p>
<p>This dehumidifier easily restores the air quality from 71% to 40% in one night. It also operates quietly, even in the fast-speed mode. However, the whisper-quiet operation comes at a cost – the fans seem to be insufficiently powerful to move enough air. It also freezes up from time to time over several months of use, which is not what you expect for the money you pay. </p>

Kesnos PD253D

Kesnos PD253D

Get peace of mind knowing that the healthy humidity level is maintained in your garage with the Kesnos PD253D.

By covering 4,500 square feet of garages and extracting 70 pints of water per day, you will be sure that your car is protected from rust. Similar to Waykar PD253B, there are two fan speed options to regulate how slow or fast you want the dehumidified air to be spread across the garage. The 1,18-gallon tank is sufficient to collect water from the moderately wet air, but you will need to empty it several times a day if the air is too wet.

Thanks to robust wheels and ergonomic handles, it’s easy to move this 30-pounds dehumidifier from one spot to another. You can easily switch between the modes or set the desired parameters using a user-friendly LCD screen. The dry mode allows you to dry the clothes faster, while the auto humidity sensor will work non-stop to monitor the air quality.

Kesnos PD253D picture

You may find it a little tricky to connect the included hose to the Kesnos PD253D. I removed the white plastic screw-on plug at first, but it didn’t work, and the water kept on filling the tank. Then I noticed a tiny black rubber plug attaching the hose. After I removed it, water poured out through the drain hole. Mind that the hose comes out occasionally, so give it a check from time to time.

Regardless of minor flaws, the Kesnos PD253D dehumidifier is a great device for restoring the optimal humidity level in your garage.

Key specs

Garage dehumidifier buying guide

How to know the humidity level in the garage?

Before you purchase a dehumidifier, it’s essential to know the humidity level in the garage. The extremely high humidity will make the item work harder, so you’ve got to be certain the device will stand the load.

The easiest and the most accurate way to measure the garage humidity level is to use a humidity meter, also known as a hygrometer.

If you do not have a hygrometer and would be satisfied with a rough estimation of the garage humidity level, you can also try an ice cube method. Fill the glass with water and put three cubes of ice in it. Wait for around four minutes, and then check the glass. If you see dripping on the outside of the glass, the humidity can be too high. If there are no signs of condensation, there could be insufficient moisture in the air.

Speed of moisture removal

The effectiveness of the garage dehumidifier is defined by how many pints of water it can remove from the air. It characterizes how effectively the device prevents rusting and corrosion, destroys mold and pests, eliminates the spread of allergens in the air, and maintains the air quality. Based on the pint capacity, there are 20, 30, 40, 50, 60, 70, and more pints dehumidifiers.

What size dehumidifier do I need for a garage?

When picking the optimal size of the dehumidifier, it’s essential to consider the size of the garage and the humidity level in it.

Make sure you pick the dehumidifier for a garage that offers sufficient coverage for the whole area. Getting the unit that exceeds the garage space is ok, but an underpowered model might turn out to be completely ineffective. The manufacturers usually provide this feature in the product descriptions.

The garage humidity level also matters. The more moisture in the air is, the more powerful the dehumidifier should be.

So, a damp garage of 500-1,500 square feet will benefit from a 30-pint dehumidifier. If the air contains more moisture or is characterized as extremely wet, you should consider the 50-pint device for the same garage size.

For larger garages (let’s say 2,000-2,500 square feet), you’ve got to get the dehumidifier that is not lower than 50 pints.

Additional factors that influence the choice of garage dehumidifier size

Aside from the garage size and the humidity level, other additional factors can make a difference.

If you live in a hot and humid climate (like Florida), it is better to add 10 pints to the required tool capacity.

Since garages are frequently uninsulated and there could be a drop in the temperature during the winter season, I recommend purchasing the device that supports the low-temperature operation.

I suggest you get a dehumidifier that is slightly larger than you need. This will ensure the unit will remove humidity from a garage in all situations. You can always run it on lower settings to reduce electricity usage.

Drainage types

Garage dehumidifiers might feature an automatic drainage system or allow manual draining.

Manual drainage is the least convenient way of removing water as it involves manually removing the water tank, pouring out water, and putting it back. Most devices have an automatic shut-off feature that would prevent leaks and puddles when the tank is full.

There are three methods to drain water automatically. Gravity draining involves attaching a hose that would drain the collected water. Many dehumidifiers come with an internal condensate pump, which would push out water when the pump is full. There is also an option of adding an external condensate pump to the humidifier if you do not want to bother yourself with manual draining.

Additional features

You may want to pay attention to the following features when selecting a dehumidifier for your garage for added convenience.

Many devices come with an auto shut-off feature, which would track the water level in the tank and shut the unit off when it is full to prevent overflowing.

The fan speed allows you to customize the pace of air circulation, which can be convenient in some situations.

You’ll enjoy the defrost feature that would keep the coils free of ice during cold winter days and prolong the lifespan of the dehumidifier.

FAQ

Can you run a dehumidifier in an unheated garage?

You can, but it will need a heat source to operate efficiently. You can run a dehumidifier year-round if the garage is heated between 60 and 65 degrees F. If the temperature drops below that range during the heating season, turn off the dehumidifier when heating is on.

How can I improve the air circulation in my garage?

Install a few ceiling fans in your garage. One is adequate for most garages, but two or more helps move the air and keep things drier. Many stores sell inexpensive “depression” type 60-CFM fans that will nicely circulate the air in your average 2-car garage.

Where should I place my dehumidifier in a garage?

Put the dehumidifier as close to the center of your garage as you can, or place it near an outside wall. You don’t want to do this in a corner because the air will be too stagnant there. If possible, turn off heating or cooling systems when using the dehumidifier.

Will a dehumidifier help with mold?

A dehumidifier is not designed to remove mold, but it will keep the humidity level in your garage below 50%, which significantly reduces or eliminates the most common household molds. You can also use fungicidal sprays to treat surfaces affected by mold after drying them with a fan.

What are the disadvantages of a dehumidifier?

The biggest drawback in using a dehumidifier is the noise they generate. For this reason alone, you may find it more practical to use fans when air circulation is not an issue.

Is it safe to run a dehumidifier constantly all the time?

The compressor motor in a typical dehumidifier is designed to run for short periods only. It is not designed to run continuously, and it should never be allowed. A normally functioning unit will shut down before the compressor does, but that depends on several factors, including the ambient temperature of where it is located, whether or not a drain hose is provided, and how often it cycles on and off.

How many hours a day should I run my dehumidifier?

In general, it is best to run the dehumidifier only when you are in your garage. If you can visit your garage often during the day, a couple of hours each time will do a good job of keeping humidity levels down.

Should I use a dehumidifier in the winter?

You can run a dehumidifier in an unheated garage year-round if the temperature stays above 60 degrees F. Below that, turn it off when you turn on heating systems. If the ambient temperature of your garage usually is below 60 degrees F during the day, heat will be required to operate your dehumidifier efficiently.

Why does my dehumidifier run but not collect water?

There are many possible causes. First, check to see if the collection bucket is empty and if the device shuts down when it is full. Next, make sure nothing is blocking the air intake or exhaust openings on top or bottom of your dehumidifier. Also, ensure that the water level float switch is working by reaching behind and pushing it up a couple of times. If that does not work, the switch may be defective and need to be replaced.
