Best Garage Dehumidifiers

Garages and moisture are not the best of friends.

That’s one of the reasons why you’d need the best dehumidifier for your garage.

Since garages are one of the most active spaces in any home, they’re also prone to a lot of things that could harm them. And guess what? One of those things is moisture and humidity.

But why is it bad for your garage and why do you need a garage dehumidifier in the first place?

Well, it’s bad because it gives room for all those unwanted molds, fungus, and mildews to settle in your space.

And where there is mold, there is trouble. Why? Because this can potentially lead to ruining things in your garage.

Think about it, would you like to come across those heaps of molds on your belongings? No, right? It doesn’t even sound too healthy.

That’s where the best dehumidifier for the garage comes into play. These units eliminate any source of moisture and practically pull in the water from the air and into their storage tanks(or drain).

Thus, keeping your garage moisture-free and ensuring that it doesn’t get too humid in there. In turn, keeping all the mold(and related problems) away.

Here’s a question though, where does all this humidity and moisture even come from? Let’s discuss.

What could be the sources of moisture in your garage?

Okay, so you must be wondering where all the moisture is coming from into your garage space. Well, to tell you the truth, there could be many sources and reasons.

  • Garage floor sweating. This phenomenon is very common in most garages as the garage floor tends to give room for moisture to settle. Here, the floor seems to stay wet all the time. It is fairly common on cold floors where the water condenses down and gives it that ‘sweaty appearance’.
  • Your car. If your car is coming from a wet area or has passed over the water, it’ll bring that inside your garage. That’s how the moisture builds up.
  • Poor ventilation. Since garages are mostly the least ventilated area of the house, they tend to have a mixture of hot/cold air. And what does that mean? Moisture in the air!
  • Compromised Insulation. Often due to poor insulation in the garage space, many a time, there’s a high chance of moisture build-up.

But what if I have a heater in my garage? Will that compensate for a garage dehumidifier? It’s time we clear it out!

Dehumidifier vs Heater: which one is better?

This topic has come up way too many times so we must address it here in our article. Hopefully, it’ll clear things once and for all.

So do I need a heater or a dehumidifier to reduce the dampness and moisture level? The answer is a garage dehumidifier!

And the reason is simple. Although a heater will reduce the dampness and heat the space it will not eliminate the humidity. Therefore, there will always be some moisture left behind in the air.

On the other hand, the best garage dehumidifier will extract the moisture out of the air and condense it into liquid water. Furthermore, it will release warm, dry air into the garage space.

So, which one seems more effective for the job? You know the answer now! Now moving on, it’s time to look through some of your options for the best garage dehumidifier.

Below are the top 10 units that caught our eye for all the right reasons. Thus, we’re hoping you find the best dehumidifier for your garage out of these as well!

Buying Guide

Now that we’re done with the garage dehumidifier reviews, it’s time for you to buy. But what are the things/features that make the best humidifier for the garage stand out?

Well, there are a few things to consider here. These include the size of the humidifier, pints per day, drainage, etc.

There are also a few additional features that can help you choose the best garage dehumidifier from the many choices. So here, we’ll discuss them all for you!


Size matters no matter what.

Thinking of the size, it’s almost unnecessary to get a garage dehumidifier that’s too big or too small for your garage space.

On top of that, there’s no general size that can fit every garage.

Other than that, a small dehumidifier for a large space may not be effective enough. Similarly, a fairly larger one tends to use far more energy than the smaller ones.

Thus, you can’t be certain of the ‘right’ size until you have an idea of your garage’s dimensions.

Here, knowing the exact ‘square per feet’ dimensions of your garage would be very helpful.

So, when you think of what size dehumidifier is best for a 2 car garage, the answer depends upon certain factors.

And what are those? Well, these can include the dampness inside your garage, the overall area size, and the external environment.

Thus, it’s on you to keep everything in mind before you settle on the best choice.

Drainage ability

The second thing that you must consider before settling on a dehumidifier for your garage has to this one: THE DRAINAGE OPTIONS and the ability.

Make sure you have a proper drainage option with your dehumidifier because you can’t let the water stay for too long.

Moreover, since your humidifier will be collecting a good amount of moisture, you’d have to empty the tank regularly.

That calls for a long time of sitting and emptying which isn’t very convenient.

So, here you’d have 3 basic drainage options with the best humidifier for the garage (in case yours does not include an additional auto-shutoff feature):

  • Tanks
  • Gravity-fed hoses
  • Built-in pumps

Tanks are generally a good option if you don’t have a drain anywhere near your humidifier or it is difficult to set up.

But to make sure your garage humidifier has ample space, you need to get a tank that has a large capacity.

However, we’d suggest you get continuous drainage. This is possible with the use of gravity-fed hoses and Built-in pumps. These help in draining any water collected away from the dehumidifier.

The gravity-fed hoses (as obvious by the title) use the force of gravity to pull out the water from the unit. Here, the water runs down the hoses.

While in the built-in pumps, the suction force pumps out the water.


Pints per day or simply ‘pints’ is the amount of water that your garage dehumidifier can remove in 24-hours.

This is directly related to the overall performance of your garage dehumidifier so it’s important to consider.

Thus, the greater the pints, the more effective and powerful your dehumidifier. However, you don’t want to over-dry your garage space so make sure you choose the right pints for your use.

The options here range from 30 pints up to 70 pints per day. But this also depends on how humid your area/region is.

So, if you live in an area where it’s very hot and humid mostly, a 60-70 pint unit will be the best dehumidifier for your garage.

Auto Shut-off

Auto-shut-off is a very smart feature and you shouldn’t miss out on it if you want the best garage dehumidifier.

This feature works brilliantly to ensure that your unit doesn’t work more than it needs to.

In simpler terms, the auto-shut-off feature is what will turn your garage dehumidifier off as soon as the tank fills up completely.

Thus, it will save your tank from overflowing and prevent any damage to the humidifier itself.


This is important for those who’re looking for the best humidifiers for cold garages.

Since these garage dehumidifiers are fitted with coils, they are prone to freeze if temperatures go too low.

And what does that mean? Your humidifier will use more power to run. But this increased power consumption can turn out to be bad for your unit as it can overheat and burn out.

However, if the best garage dehumidifier does come with defrosting ability, you’re good.

The defrost function here will ensure that your coils won’t heat up too much because of the ice. Thus, saving them from burning and saving energy.

Noise level

Lastly, the noise levels.

You don’t want your garage dehumidifier to add to the existing noise in your garage, right?

That’s why you need to make sure that your unit does not fall in the ‘noisy’ category. But how would you determine that?

Firstly, it’s very clear that a big garage dehumidifier will always seem noisier in a small garage space than in a spacious one. So that’s something to consider.

For this, many manufacturers mention the unit’s decibels which correspond to the noise levels. So what is the best desiccant dehumidifier in reality?

The one that does not annoy you with its noise levels and that’s what you should be getting!

Frequently Asked Questions (FAQs)

Is a dehumidifier good for a garage?

Of Course, it is! A good garage dehumidifier is a great tool to help you get rid of that excess moisture in your garage.

What size dehumidifier do I need for my garage?

This depends on the size of your garage. Hence, first, you need to know how much area you want your garage dehumidifier to cover.

In the case of a big garage then, you’d need a unit with greater pints (about 50-70 pints).

However, for smaller, more compact ones, a small-sized dehumidifier will be good enough to remove moisture from the air.

How do I keep moisture out of my garage?

There are several ways and tricks that you can use to keep your garage space moisture-free. These can include:

  • Proper ventilation
  • Installing a garage dehumidifier
  • Temperature control
  • Making sure your garage floor doesn’t remain wet for long
  • Using a vapor barrier to keep the air moisture-free
  • Getting your garage floor coated to prevent any water from collecting

Does a dehumidifier work in a cold garage?

Yes, it does! But you’d have to have a very keen eye and proper knowledge of the best garage dehumidifier for that.

That’s because every dehumidifier out there can not stand up to harsh cold temperatures.

For this, you’d need a unit that comes with a defrost option. Here you can try a compressor-powered garage dehumidifier that uses hot gas to defrost the coils if they get covered in snow or become too cold.

However, a better choice would be a desiccated dehumidifier that works perfectly irrespective of the conditions.

At what temperatures do dehumidifiers stop working?

Generally, a good garage dehumidifier would be able to withstand extreme temperatures. However, any temperature below 60 degrees Fahrenheit is not ideal for dehumidifiers.

That’s because these temperatures can badly affect the unit’s coils and interrupt its working.

Should I run my dehumidifier continuously?

No that’s not necessary.

Even though running it for a longer time can ensure that your garage has adequate humidity and suitable temperatures, it’s not important to do so.

But make sure you keep the filter clean and regularly clean/drain the collected water.
