Why Would You Need a New Garage Dehumidifier?

In case you’re still wondering if you really need a dehumidifier for your garage, let us tell you that using this type of product for your garage does a lot more than just dehumidify it.

The lower levels of humidity in a room are the biggest saving factor from mold. Mold not only grows in damp areas, damaging everything that it touches, but it is also toxic when inhaled. It’s therefore important to get rid any present, right away. And there is no better way of doing that than a dehumidifier.

Furthermore, humidity can cause corrosion of your vehicle and give rise to fungus and mildew too. A garage dehumidifier would kill the levels of humidity, saving you from all these problems in the longer run.

Aspects to Consider Before Buying

Before you pick a dehumidifier for your garage, you need to understand what important aspects need to be considered.

Space of Garage

It is very important to consider the amount of space the dehumidifier will be required to cover. Different units are designed to cover different sizes of spaces and you need to find one that matches your requirements.

The Levels of Humidity

Another important thing that you need to consider is the level of humidity in your garage. Some devices may not work as efficiently to remove a huge amount of moisture from the air and may not work well in rooms with high levels of humidity

Drainage

Dehumidifiers come with two types of drainage systems for the water that is removed from that air. First is the tank approach, in which the water is collected in a tank that is manually removed and drained. The other is through a drain hose which continuously empties the water into a drain. You have to consider factors like the availability of a drain and constant emptying of the tank before choosing the mode of drainage.

Now that we have established all the important concepts, like the need for dehumidifiers and all the important aspects that need to be considered, we can finally move on to picking the right one. To help with that, here are some of the best dehumidifiers that function ideally for a garage.

Review

The Shinco SDO is a solid unit for gearheads, auto enthusiasts, or those who just seem to get a bit of extra moisture in their garage after a rain. It earns a 5-star rating for affordability and a 5-star rating for cost efficiency, highlighting its overall value as a bargain purchase. And with the lowest weight on the list and accompanying handles and wheels, you can move the Shinco wherever you need it to absorb the most water.

Bottom Line

Though the unit has just a 2-star rating for its short warranty, it remains perhaps the only downside of the Shinco SDO. If you’re looking for quick water absorption across a large coverage area and a few extra bells and whistles, put this dehumidifier on your radar.

Pros

Automatic shut off

Two drainage options

LED display for easy operation and a humidistat

Inside drying button to eliminate moisture before storage

Covers 2,000 sq. ft., which is enough for even commercial garages

Cons

Short drip hose

Louder than advertised

Review

Going toe-to-toe with the Shinco SDO, this JHS dehumidifier comes with 5-star ratings for both cost efficiency and affordability. This translates into a great value, especially when you’re trying to keep your garage free from excess moisture and mold. Empty it by hand or hook up a garden hose and let the water flow out on its own, which is a handy feature for the absent-minded garage-lurker.

Bottom Line

While it’s slightly larger than some of the other units on this list, it’s still surprisingly portable with the included wheels and handles. However, it’s not quite as good in terms of space efficiency-to-water absorption as the Shinco, which is perhaps the only reason it falls to #2 on the list. Otherwise, it’s a great unit for the money and dehumidifying power.

Pros

Easy control panel

Energy Star certified

Power outage restart

Intelligent humidity control

Manual or automatic drain through a garden hose

Cons

Poorly written manual

Louder than other units

Review

Colzer has long been a strong brand name in the dehumidifier space and the HD08C is no different. Earning slightly lower ranks of 4.5 stars for both cost efficiency and affordability, you might be paying a bit more for the brand name. However, it covers 3,500 square feet, making it one of the more capable options for large garages, and also has four casters and two handles to ensure you can place it anywhere you want.

Bottom Line

Though the space efficiency, or amount of water it removes compared to the size, is a bit lacking, this Colzer dehumidifier is a proven workhorse in the garage dehumidifier realm. And with three modes for continuous dehumidifying, a smart mode, and even a dry mode, it’s a bit more versatile than some other dehumidifiers available.

Pros

Child lock

Covers 3,500 sq. ft.

Dual drainage options

24-hour programmable timer

Three dehumidifier settings for maximum control

Cons

Small tank capacity compared to similar units

Problems with sensor malfunctions in rare cases

Review

The Shinco SDZ1 picks up where the Shinco SDO left off, offering more water absorption than its sibling while matching its 4.5-star space efficiency and cost efficiency ratings. But when you need to clean up a wet area or just keep things dry in the garage, you’ll feel the effects of those 10 extra pints of absorption. And as it’s much lighter weight than the Colzer and other 50-pint units, it gets a 4.5-star portability rating, which can come in handy if you need to move the unit throughout your garage.

Bottom Line

Though you don’t always need a noiseless dehumidifier in a garage, the Shinco SDZ1 has a whisper-quiet operation to go along with maximum portability and affordability. While it lags behind with only a 2-star warranty rating, the SDZ1 is still a formidable dehumidifier that’s ready for any challenge you throw its way.

Pros

Energy Star rated

Covers 3,000 square feet

Full LED display with humidistat

Sleep timer for the forgetful garage-dweller

Automatic 24-hour cycle with automatic shutoff

Cons

Short drainage tube can cause issues

Controls can be confusing for some users

Review

Honeywell doubles down on its reputation as a top-notch brand by offering a 5-star warranty that’s one of the best in the industry. It also has a cord winder, four casters, and heavy-duty handles capable of carrying up to 150 pounds, giving it added durability compared to some of the more flimsy models available for garage dehumidifying. But with similar water absorption to other units on this list, you might just be paying a bit more for the Honeywell name.

Bottom Line

If you want something that’s going to last and the peace of mind to go with it, this Honeywell dehumidifier should leave you feeling like you’re walking on sunshine. However, its 3-star affordability rating plunges it to the bottom of the list. It’s still a first-rate unit; just be prepared to shell out a little more.

Pros

Covers 3,000 sq. ft.

Cord winder for easy storage

Easy-to-read digital LED display

Anti-spill design for easy water disposal

Smart feature turns unit on when it senses a rise in humidity

Cons

Far more expensive than other similar garage dehumidifiers

Problems with water draining through the hose in some instances

Conclusion

A dehumidifier for your garage is absolutely necessary. You need to keep all the items present in the vicinity safe from the harmful effects of excessive humidity and provide better breathing for yourself. The smartest thing to keep in mind are the aspects that need to be considered and pick the best dehumidifier right away!
