Garage Dehumidifier: Best Dehumidifier For Garage Workshops

Trying to figure out what size dehumidifier for garage or workshop you need? Or are you looking for a good garage dehumidifier that will last for years? Then you’ve come to the right place.

Many workshops need a dehumidifier, especially garage workshops, but also workspaces in basements and warehouses. Almost every maker or professional craftsman can benefit from having a dehumidifier in storage spaces like closets.

As we mentioned in our guide to plastics for 3D printing, you will be surprised by how much moisture your materials and appliances can pull out of the air. Over time, that extra moisture can build up and cause mold and all kinds of rot and rust.

Our top choice out of all of the dehumidifiers on this list is the Frigidaire 70-Pint Dehumidifier for these reasons:

  • Very quite, low noise profile
  • Energy saving features save money on electricity
  • Most popular dehumidifier for both homes and workshops
  • Over 2000 customer reviews on Amazon

Finally, we included a few even smaller dehumidifiers that you can set up on a desk in your office. A great example is the Pro Breeze Electric Mini Dehumidifier, which is perfect for offices, bedrooms, bathrooms, or closets.

The Ivation 70 pint dehumidifier can dehumidify your entire house. It has a nice digital screen that displays several settings, including an eco-friendly energy efficient option.

You can set this humidifier and forget it, especially if you make use of the garden hose attachment for drainage. Otherwise, you will have to periodically empty the built in bucket, which takes a little getting used to, but is easy enough.

Also the unit shuts off when it’s full, and can be pushed easily across the floor. That extra mobility makes this dehumidifier reduces the effort that is needed to set it up or store it awa when you are done using it.

One other benefit is that it produces some hot air, so it can double as a heater. In fact, some customers use it to remove humidity in the summers and warm up their workspaces in the winters.

The only real downside to this unit is that it is a bit loud. The noise is comparable to a fan set on high. It can be reduced if you find the right settings and it won’t matter much if you are using this humidifier for a space that is out of earshot.

Have you ever bought a dehumidifier that stopped working after a few months?

Probably the best thing about the Oasis D-165-HG commercial grade dehumidifier is it will last for years. Cheaper dehumidifiers might have more bells and whistles than this unit, but they won’t out last this machine.

You can trust Oasis: Oasis has been making dehumidifiers and water filtering equipment since 1910, so they know what they are doing.

The D-165-HG model is a durable, long-lasting piece of equipment with a dial-controlled humidistat so you can program the unit to turn off at certain moisture levels. Some users have had to troubleshoot the unit when it first arrives, but once the thing turns on, it stays on.

But don’t worry: It comes with a 5 year warranty so that in the unlikely event that something goes wrong, you can get it replaced free of charge.

4. EdgeStar 50 Pint Portable Dehumidifier – White

Check Price

The EdgeStar 50 Pint compact dehumidifier perfect for short term use. It comes in handy for times when moisture levels are particularly high in your workspace, such when your sump pump over flows in your basement or during humid summer months.

We don’t recommend relying on the Edgestar for year-round dehumidification though. As a cheaper option, its lifespan is usually not longer than 2 years. This makes it a good option for seasonal dehumidification.

However, the EdgeStar is super easy to use and smaller sized so that it won’t take up much room in your workshop. You will have to empty the water collection bucket a bit more often than with larger dehumidifiers. But it also comes with a hose attachment in case you want it to be completely hands off.

The IVADM35 can remove about 20 oz. of water from 80% humidity air per day, which is pretty good for such a cheap dehumidifier.

The water container is super easy to empty and it’s super quiet. In fact, it is so quiet that one customer was even able to use it in their professional music studio and the recording microphones didn’t pick up any sound from it.

So if you are looking for a dehumidifier that is inexpensive, quiet, and doesn’t use much electricity, then this is the one for you.

IVADM45 is also very quiet, and you won’t hear anything unless you are standing right next to it.

Top 10 Frequently Asked Questions About Garage Dehumidifiers

1. Is a garage dehumidifier different from a regular home dehumidifier?

Not exactly. You can use a regular home dehumidifier in your garage, although there are garage dehumidifiers built for garages and workshops. Ivation dehumidifiers do work well for garages and workshops.

That being said, noise is not always as big of a consideration for garage duhumidifiers. You can also buy a dehumidifier with a drainage hose if your garage has a drain.

2. What size dehumidifier for garage workshops is needed?

That really depends on the size of your garage, but 70 pint dehumidifiers are usually good enough for most garages and workshops. But even a mini dehumidifier will remove enough moisture from the air to make a difference.

3. Is the Ivation or Frigidaire the best dehumidifier for garage and basement areas?

The Frigidaire 70-pint and Ivation 70-pint dehumidiers are both very good for garages and basement workshops. Our recommendation is the Frigidaire though, only because it is so popular and well recommended by customers.

The Frigidaire 70 pint dehumidifier is the best garage dehumidifier overall. It has a complete range of features and highly rated by users.

5. Which is the best dehumidifier for my garage in summer?

Summer is a particularly humid time in many climates. That means a dehumidifier for garage in summer will pull a lot more water out of the air than during the winter.

In order to handle the extra water, it is a good idea to get a dehumidifier with a larger water tank. We recommend buying a dehumidifier with at least a 70 pint water tank.

For industrial spaces, it’s best to go with a more powerful dehumidifier, like the Dri-Eaz Revolution LGR Dehumidifier. It is built to handle spaces of up to 7000 sq. ft.

7. Which workshop dehumidifier will last the longest?

That is hard to say, but many customers find that Frigidaire dehumidifiers last for several years in your home or workshop. Otherwise, take a look at Dri-Eaze industrial dehumidifiers that are built for professional applications.

8. What is the best dehumidifier for a garage with no drainage?

Without a drain, you will not be able to use a dehumidifier with a drainage hose. That means you will need to buy a dehumidifier with a water tank and empty the water tank periodically.

9. Which garage dehumidifier with pump should I buy for large spaces?

The Ivation 70 Pint Energy Star dehumidifier has a pump and a large capacity compressor for spaces up to 4,500 sq. ft. For larger spaces, check out Dri-Ease industrial dehumidifiers.

10. What is the quietest dehumidifier for garage workshop spaces? Which garage dehumidifier is the least noisy?
