TOSOT 4,500 sq ft Dehumidifier: Best Overall

See price & reviews


Being one of the leading & top-notch manufacturers of air conditioners and dehumidifiers, TOSOT is a trusted, reliable brand that ensures quality performance in its products.

With a 4,500 sq ft coverage area, the TOSOT dehumidifier is the best garage dehumidifier for larger spaces. Not to mention the 50-pint extraction rate it provides, making it draw moisture quite well for a large area.

However, we would’ve preferred that TOSOT kept its original rating of 70 pints in its previous model for an even larger capacity and extraction rate.

Drawback aside, we love the continuous drain option, Energy Star rating, and quiet operation it provides.

You need to drain the water out of the bucket every 5 hours. Luckily, the continuous drain option takes the manual hassle away, although you’ll have to spend extra for a hose and a specific area for where the hose will run into.

Otherwise, you could just manually drain the bucket. We recommend you keep a reminder to prevent damaging your dehumidifier long term-wise.

Thanks to its Energy Star rating, not only is it efficient, but it also helps you save on electricity costs. Think about it. Your garage dehumidifier running 24 hours a day can be a hefty added utility cost.


Design-wise, the TOSOT dehumidifier comes with easy to set up and operate electronic controls along with easy-to-clean filters and a light indicator to signify it needs cleaning.

With 250 hours of continuous use before it needs cleaning, it truly is an efficient dehumidifier. Furthermore, its power outage restart feature is a lifesaver in the event of any electrical interruption or blackout.

Once the power comes back, your humidity settings will remain the same.


  • Covers 4,500 square feet
  • Easy operation and setup
  • 50 pints extraction rate
  • Continuous drain option
  • Easy to clean
  • Energy Star rating
  • Power outage restart feature
  • Operates at 48 dB


  • You have to spend extra on the hose

Ivation 4,500 sq ft Dehumidifier: Best Value

See price & reviews


You’ll have to pay a little extra to get your hands on the Ivation 4,500 square feet dehumidifier, but we promise the most value in return for your money.

With a dehumidification performance of 70 pints per day, it’s the perfect garage dehumidifier for the largest areas. The lowest a dehumidifier can go is 30 pints, while 70 pints are rated as the highest performance.

You might think that a high-performing dehumidifier would also spell trouble for utility costs. However, this 70-pint dehumidifier comes with an Energy Star rating for a practical and energy-saving operation.

The Ivation 4,500 sq ft dehumidifier even comes with a filtration system, thus boosting the air quality, enhancing the filtration of mildew & allergens, and effectively removing moisture.


Just like the TOSOT dehumidifier, Ivation also provides a continuous drain option except that it also includes a pump, so you don’t have to spend extra and can drain water easily out of your garage.

Even if you wanted to drain the water bucket manually, Ivation made sure to include a 2.25-gallon water tank, so you don’t have to drain the water frequently.

Last but not least, the variety of features offered is truly where Ivation shines. It comes with an auto-defrost feature and LED display for controlling fan speed, humidity levels, and signifies when the filter needs to be changed.

At under $300, you get high-quality performance, a large coverage area, and a wide range of features that we consider to be a steal for its price.


  • Great price value
  • 70 pints extraction rate
  • Energy Star rating
  • Filtration system for enhanced air quality
  • Large water tank capacity
  • Auto-defrost feature
  • Continuous drain operation
  • Easy operation


  • Power cord is quite short

Pro Breeze Electric Mini Dehumidifier: Best Budget Pick

See price & reviews


For a smaller garage, the Pro Breeze would suit you perfectly.

The Pro Breeze Electric dehumidifier is ideal for covering areas between 220 to 250 square feet, making it just as ideal for your workshop even!

Despite its compact frame, the Pro Breeze comes with a 52 oz water tank, meaning it efficiently reduces moisture by one pint per day. Not bad for a mini dehumidifier.

This efficiency is also ideal if you want to remove fungus, mold, and mildew growth. Even better, you can leave the Pro Breeze Electric dehumidifier to run for three days without having to drain the water tank.

Combine this with Pro Breeze’s Thermo-Electric Cooling technology, and you get a quiet operation that won’t disturb you or your guests while it’s running.


The Pro Breeze is simple and straightforward to use. There are no complicated features to worry about, although it doesn’t come with a continuous drain option.

As much as manually draining your water tank might seem like a chore, the Pro Breeze doesn’t make that an issue.

It also comes with an auto-shutoff feature to prevent overfilling or leaking issues.

The only drawback is it requires heavy maintenance if your garage has high humidity levels. It’s also not ideal for areas with temperatures below 59 oF.

Nevertheless, the excellent energy efficiency, affordable price tag, and dehumidification performance make the Pro Breeze a well-praised choice for any small space.


  • Excellent energy efficiency
  • Budget-friendly
  • Auto-shutoff feature prevents leaking
  • Quiet operation
  • User friendly
  • Suitable for a smaller garage and space
  • Great dehumidification performance


  • Not ideal in areas with temperatures above 59 oF

hOmeLabs 3000 sq ft Energy Star Dehumidifier

See price & reviews


Compared to Frigidaire and TOSOT, hOmeLabs is a newcomer to the dehumidifier market. How does it compare in quality? Let’s find out.

The hOmeLabs Energy Star dehumidifier provides the same capacity as Ivation, seeing how it’s also a 70-pint dehumidifier.

Seeing as how hOmeLabs can extract 70 pints of moisture per day, it’s ideal for areas as large as 4,000 square feet. We recommend using this dehumidifier strictly in spaces between 2,500 to 4,000 square feet.

Using it in any smaller area may cause too much heat. We love the customizable humidity settings and its easy operation feature.

Despite its large capacity and high power, it’s highly efficient, hence the Energy Star rating.

Expect this 70-pint dehumidifier to run for a full 24-hour timeframe before automatically shutting off to prevent continuous power consumption.

Furthermore, it also features a continuous drain option; however, you have to buy the hose separately, sad to say.


If there’s one feature that stood out with the hOmeLabs Energy Star dehumidifier, it’s their turbo mode setting.

This allows you to increase the fan speed from 165 CFM (cubic feet/minute) to 188 CFM for maximum odor and moisture removal.

We also like how hOmeLabs added wheels and handles for improved portability should you decide to use it in a room apart from your garage.

However, hOmeLabs’ water tank capacity is relatively small. For high humidity areas, this may require frequent draining of the water tank. That being said, it’s likely you’ll have to purchase a hose for continuous drain operation.


  • 70-pint extraction rate
  • Large coverage area
  • Energy-efficient
  • Portable
  • Customizable humidity settings and fan speed
  • Ideal for a larger garage


  • Hose must be purchased separately
  • Water tank capacity is quite low

Yaufey 1500 sq ft Dehumidifier

See price & reviews


If you’re looking for a garage dehumidifier ideal for medium-sized spaces like 1,500 sq ft, Yaufey fits this description perfectly.

Capable of removing up to 4 gallons or 32 pints of moisture per day, it’s an excellent garage dehumidifier both performance and price-wise.

In fact, the Yaufey dehumidifier is just as budget-friendly as the Pro Breeze, only that it provides a larger capacity.

A 1.8L water tank isn’t that great; however, Yaufey made sure to include the continuous drain option and a 2-meter hose, so you don’t have to worry about manually draining the water tank.

It’s also worth mentioning the high number of positive reviews Yaufey has despite being less popular or renowned as leading dehumidifier brands such as TOSOT or Frigidaire.


Like the hOmeLabs dehumidifier, Yaufey also has customizable fan settings for efficient and effective removal of moisture, mold, and mildew.

Additionally, it also features an auto-defrost function, power outage restart ability, and low-fan noise for a quiet operation.

Finally, the Yaufey dehumidifier also comes with a handle and built-in wheels for improved portability. If you think about it, this unit has a fair combination of features from most of the garage dehumidifiers mentioned here.

At under $200, the Yaufey dehumidifier is perfect for any budget.


  • Budget-friendly
  • Auto-defrost feature
  • Power outage restart function
  • Continuous drain option with hose included
  • Ideal for a medium-sized garage (1,500 sq ft)
  • Customizable fan settings
  • Decent energy-efficiency


  • Some units were defective in the past

How to Choose the Best Dehumidifier for Garage

Even with 5 of the best dehumidifiers for garage models available, it can be confusing to choose the ideal dehumidifier for your garage.

For this reason, we’ve outlined this section to talk about crucial elements in the design and performance of dehumidifiers to gauge which of these elements suit your needs best.

Choosing the best dehumidifier for garage or basement purposes depend on 5 elements:

  1. Performance
  2. Capacity & drainage
  3. Extra features
  4. Noise level
  5. Temperature

We’ll discuss each element in-depth and provide you with the best recommendations per element.


The performance of each dehumidifier varies depending on its extraction rate. The extraction rate pertains to the ability of your dehumidifier to pull moisture from the air.

A good quality dehumidifier should be able to remove moisture from the air sufficiently along with regulating the humidity levels.

One way to measure the performance of dehumidifiers is through pints. Throughout the review, we mentioned a handful of pint measurements, such as 50 pints, 70 pints, 30 pints, etc.

You’ll find various dehumidifiers for garage models that offer either 30 pints, 40 pints, 50 pints, or 70-pint ratings. The number also indicates the amount of moisture from the air it can remove in a 24-hour timeframe.

For example, a 50-pint dehumidifier can remove up to 50 pints of moisture from the air per day. On the other hand, a 70-pint dehumidifier can remove up to 70 pints per day.

How to Choose a Dehumidifier Based on Performance

Go for a 30-pint dehumidifier if you have a smaller garage, while a 50 or 70-pint dehumidifier for a larger garage. It’s worth noting that the pint rating influences the efficiency of your dehumidifier.

This means that if you use a 30-pint dehumidifier for a large garage, it wouldn’t efficiently regulate the humidity.

Likewise, a 70-pint dehumidifier wouldn’t work best for a smaller garage since this may lead to causing too much heat or waste a lot of energy.

Capacity & Drainage

The capacity of your garage dehumidifier goes hand-in-hand with drainage capability and dehumidification performance.

Dehumidifiers will typically show the square footage on the product label or manufacturer’s website. It’s absolutely vital you make sure to check the square footage or capacity before choosing the best dehumidifier for your garage.

The capacity tells you how much space your dehumidifier can cover. To effectively regulate humidity and pull moisture from the air, your dehumidifier should be able to cover the square footage of your garage adequately.

For example, a 3,000 or 4,000 sq ft dehumidifier works best for a larger garage, while a 1,500 sq ft dehumidifier works best for a medium-sized garage.

As for the drainage capabilities, this refers to the option of having a continuous drain hose or automatic shutoff features. Mostly, these relate to your convenience and ease of maintenance.

How to Choose a Dehumidifier Based on Capacity & Drainage

We recommend getting an accurate measurement or square footage of your garage and match this with the dehumidifier that provides the appropriate coverage area.

A 3,000 to 4,000 sq ft dehumidifier should be adequate for a 3,000 to 4,000 sq ft garage. Smaller garage models can cover up to 200 feet only, so make sure your garage measures around the same dimensions too.

We don’t recommend “eye-balling” the square footage of your garage. If your garage measures at 1,500 sq ft and you get a 3,000 sq ft unit, this makes it less efficient and costly on your part.

This is what makes choosing dehumidifiers tricky. However, for optimal humidity regulation and pulling moisture from air, it helps to select the right measurements.

As for drainage capabilities, it’s always best to choose a unit with a continuous drain hose and automatic shutoff features.

Without it, your unit could experience overfilling or leaking and having to manually drain your water reservoir, which can be challenging if you’re out on a trip and want to keep your vehicle well-protected.

Extra Features (Adjustable Settings, Portability, & Warranty)

Extra features are all about convenience, usability, and user-friendliness. Adjustable settings pertain mostly to changing the humidity or setting the preferred humidity in your garage.

Not only will this save you energy, but it also helps you achieve optimal regulation and effectively pulling moisture in the air.

Portability and warranty coverage are features that are preferred but not as necessary.

A garage dehumidifier you can easily move around is useful, especially if you buy a large unit. Some units may also come defective, which means that warranty coverage can be beneficial for cases like these.

How to Choose a Dehumidifier Based on Extra Features

A dehumidifier that provides adjustable settings for fan speed and humidity are excellent picks. If the unit doesn’t have any, try to get a unit that accurately matches the appropriate capacity and dehumidification performance.

Nowadays, most dehumidifiers will come with adjustable settings and are also quite affordable.

We recommend choosing a unit with built-in wheels and handles if you have plans to use this dehumidifier for other areas in your home. Suppose you plan to buy a large or heavy unit, opting for built-in wheels and handles suits you better.

On the other hand, trusted brands such as Frigidaire, TOSOT, and hOmeLabs, Ivation, and Yaufey all come with warranty coverage.

When choosing the best dehumidifier for garage, it’s always best to go for trusted, quality brands. Not only will this ensure good warranty coverage but also reliable quality overall.

Sound Level

Even though your dehumidifier will mostly be stored in your garage, considering the sound level or noise operation of your unit is a vital element.

Some dehumidifiers operate too loud that it can be irritating after continuous use. This is especially true for dehumidifiers with a higher pint rating.

Since dehumidifiers operate through compressors, this is usually the source of the noise. However, not all dehumidifiers with a large pint size mean a noisy operation.

Some manufacturers will consider different factors and use different components leading to a quiet operation.

One example would be the Pro Breeze Electric dehumidifier, which runs on a Thermo-Electric Cooling technology instead of a compressor.

How to Choose a Dehumidifier Based on Sound Level

It’s best to always ask for the dB or decibel rating of the unit before buying one, which you can find on the manufacturer’s label or website.

Don’t expect to find a unit that’s ultra-quiet, either. Any machine will always produce some audible noise, and it’s nearly impossible to find a completely quiet unit.

Dehumidifiers with a rating between 40 to 70 dB should be pretty quiet and more than adequate for satisfying adequate noise levels.


Furthermore, it would help if you considered the temperature of your garage. Garages with temperatures of 59 oF shouldn’t pose a problem.

However, if the temperature of your garage drops below 59 oF, you should consider a dehumidifier with an auto-defrost feature.

How to Choose a Dehumidifier Based on Temperature

Getting a unit with an auto-defrost feature will remove any frost build-up, which is essential to your compressor’s health and effectiveness in reducing moisture in the air.

The Best Dehumidifier For Garage

The best garage dehumidifier should prioritize dehumidification performance and capacity above all.

Choosing the appropriate pint-size and capacity significantly affects how effective your dehumidifier will be able to pull moisture in the air and regulate humidity.

To get the best results for effectively removing mold, fungus, and mildew, along with protecting your vehicle at all costs, these two elements, pint-size and capacity, should be essential elements to look out for first.

For example, if your garage measures 3,500 sq ft, an ideal dehumidifier would be a unit with 50 pints at the very least, 4,000 sq ft coverage, and preferably with adjustable settings and an Energy Star rating to save on energy costs.

A more concrete example would be our top three picks mentioned in this review:

Best Overall: TOSOT 4,500 sq ft Dehumidifier

The TOSOT 4,500 sq ft is the best dehumidifier for garage spaces seeing as how it covers all the essential elements discussed in the previous section.

It’s also worth mentioning that the TOSOT dehumidifier is quite affordable considering the features it comes with. However, we also understand that the TOSOT may not be for everyone.

For this reason, we recommend this dehumidifier if you’re looking for a price-friendly unit with excellent dehumidification performance, energy-saving & quiet operation, and have a fairly large garage.

Best Value: Ivation 4,500 sq ft Dehumidifier

The Ivation 4,500 sq ft dehumidifier is another one of our best dehumidifiers for garage spaces.

You might have to spend a little more compared to the TOSOT dehumidifier. Still, in return, you get an auto-defrost feature, 70-pint size for the largest garage space, Energy Star rating, and a hose for continuous drain operation.

Unlike the TOSOT 4,500 sq ft dehumidifier, you’ll have to buy a separate hose, and it also doesn’t come with an auto-defrost feature.

We highly recommend the Ivation 4,500 sq ft as the best dehumidifier for garage spaces up to 4,000 sq ft and need a unit capable of handling temperatures below 59 oF.

Best Budget Pick: Pro Breeze Electric Mini Dehumidifier

The Pro Breeze Electric is the best garage dehumidifier for those with smaller garage spaces. Even though the Pro Breeze can only cover 220 to 250 square feet, its efficiency is also the highest on our list.

Compared to a 50-pint dehumidifier, the Pro Breeze provides higher energy saving costs and quieter operation.

The best part? It’s a lot cheaper than buying a 70 or 50-pint dehumidifier.


We hope this review was able to help you choose the best dehumidifier for your garage! As far as premium quality and performance goes, always be sure to choose a dehumidifier that suits your needs.

Don’t choose a humidifier simply based on what the label says or because all your friends have the same one. Ultimately, as the end-user, the best dehumidifier for you is one that satisfies most, if not all, of your needs.
