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

- Industrial: These are the most heavy duty dehumidifiers for garages and warehouses. They usually use a drainage hose and are built for spaces up to 7000 sq. ft.
- Large: 70 pints, these dehumidifiers are well built for large spaces and are our recommendation for garage workshops, up to 4000 sq. ft.
- Medium: 50 pints, perfect for open living spaces and smaller workshops that are 1000 – 3000 square feet
- Small: 24 oz., even small dehumidifiers can vastly improve the air in a room. They are perfect for single rooms and smaller workshops that are 300 – 1500 square feet but not much bigger.
- Mini: 16 oz., these are great for smaller rooms and closets such as bathrooms and office workspaces or dorm rooms that are around 300 square feet or less. You can put one on a work table or desk and improve the air quality immediately.
We included heavy duty commercial grade dehumidifiers like the Dri-Eaz 18-gallon Compact Portable Refrigerant Dehumidifier since these are often suitable for larger workshops or professional construction sites. But we’ve also reviewed medium sized home dehumidifiers that you can set up in your living room or put crawl space.
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.

It features automatic turnoff and control lock settings, hands and wheels for easy maneuverability and electronic controls for easy set up. And you can rely on this dehumidifier to work effortlessly for years, especially if you set it up near a drain so that it can empty automatically.
With a sleek design and quiet sound profile, you can install this unit anywhere in your office, basement or living space. And the as the customers on amazon can tell you, it is great choice for a garage dehumidifier.

2. Ivation 70 Pint Energy Star Dehumidifier
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.
3. Oasis D-165-HG GST Commercial Grade Dehumidifier
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.
The D-165-HG GST is an efficient mid-level model from Oasis and can remove 40 pints of water from the air in 24 hours. If you are looking for a reliable, high quality dehumidifier that won’t need to be replaced for a long time, this is the one for you.
4. EdgeStar 50 Pint Portable Dehumidifier – White
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.
5. Ivation IVADM35 Powerful Thermo-Electric Dehumidifier
The Ivation IVADM35 dehumidifier is smaller than the Ivation 70 pint Energy Star model, and it’s compact size makes it perfect for small rooms and workspaces. Many people even buy one of these for their camper van.
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.
6. Dri-Eaz 18-gallon Compact Portable Refrigerant Dehumidifier
The commercial grade Dri-Eaz F203-A is a beast. This heavy-duty, refrigerant dehumidifier can remove up to 145 pints of water from the air per day.
That is a staggering amount of dehumidification power.
In fact, one customer reported that the Dri-Eaz F203-A filled half a trash can with water overnight. So if you are looking for a dehumidifier built for use in large homes, apartment complexes, industrial sites, garages in tropical weather conditions or other highly demanding environments, the F203-A is a perfect choice.
It also features large wheels that make it super easy to move, which is important because this thing is heavy. And a 25’ power cable ensures that you can plug it in pretty much anywhere and operating it is super simple.
Also, Dri-Eaz has great customer service, so if you have any questions you can give them a call immediately.
All of these features make the Dri-Eaz on of the best garage dehumidifiers on this list.
7. Dri-Eaz F413 Revolution LGR Dehumidifier, 12.5 inches
The Dri-Eaz F413 Revolution is another commercial grade, heavy-duty garage dehumidifier, and this one is built for tighter spaces and easier storage. Its compact, rectangular design makes it easy to stack and store away in boxes and on shelves.
Moreover, the Revolution is small enough to fit into crawl spaces and between machinery so that you can bring industrial strength dehumidification to hard to reach areas. And with Dri-Eaz’s rugged rotomolded housing, the Revolution will last for years in the harshest conditions.
The only problem that some customers have experienced with this machine is occasional leaking. If that happens to you, simply contact Dr-Eaz and they will replace the unit free of charge.
8. Ivation IVADM45 Powerful Mid-Size Thermo-Electric Intelligent Dehumidifier w/Auto Humidistat – For Spaces Up to 2,200 Cubic Feet
The Ivation IVADM45 is perfect for small workshops or offices. It can handle larger rooms as well, but since it only removes around 25 oz of water from the air per day, the IVADM45 is more effective in smaller spaces.
This is the one of the best dehumidifiers for garage workshops simply because it is built with this purpose in mind. The IVADM45 has energy saving features, such as an automatic shutoff feature that kicks in when the unit is full and requires less energy to run over all.
IVADM45 is also very quiet, and you won’t hear anything unless you are standing right next to it.
Combined with it’s energy saving features, you can use this dehumidifier to remove water from your workspace instead of relying on central air conditioning and regular air conditioning units.
That will save a lot of money on your electricity bill overtime.
