How to choose the best dehumidifier for garage

If this is your first time buying a dehumidifier for your garage, it’s important to consider the following aspects:

✔️Coverage area

First, you should consider the floor area of your garage. Dehumidifiers are always rated based on the maximum floor area they can cover. This ensures that the unit is matched to the amount of moisture in the area.

Take note that getting the right dehumidifier size is also a matter of energy efficiency. A dehumidifier that’s too small for your garage will consume more electricity than it’s supposed to. Worse, it will spike up your energy bill while doing very little to control the humidity in your garage.

If your place is notorious for extremely high relative humidity (RH), you should consider getting a bigger humidifier. With that, you should always check the rating of the dehumidifier by square feet. You should compare this to the size of your garage.

Whatever capacity you choose, make sure that the unit has a built-in humidistat. This will detect the humidity level of your garage and adjust the dehumidifier’s operation based on your target moisture level.


A dehumidifier’s capacity dictates how much water it can suck out from the air within a day. This is often measured in PPD or pints per day.

If your garage has excessively high RH, you should get a high-capacity unit. A dehumidifier with at least 30 pints of extraction capacity is a champ, but you can always bigger ones ranging from 50 to 100 pints. While there are dehumidifiers with 200-pint dehumidifiers, I think it’s already overkilling for your garage.

Aside from the extraction rate, you should also check the tank capacity of the dehumidifier. This is often measured in gallons or liters. The bigger the tank, the better if you’re dealing with too much moisture to deal with.

✔️Drain options

The next thing you should consider is the drain method of the garage dehumidifier. Most dehumidifiers nowadays offer manual and continuous drain options.

The good thing with garages is instant access to the outdoors. This makes continuous drain a practical choice, especially if you’re dehumidifying after flooding or severe water damage.

A hose is connected to the dehumidifier with a continuous drain, which is funneled into a sink or outside the garage. But if this setup isn’t possible, you can opt for the manual drain, which involves emptying the water tank inside the dehumidifier.


Dehumidifiers are fitted with filters to trap large air particulates, including dust, pollens, and animal fur. Note that its main function isn’t to clean the air fully but only to reduce airborne contaminants.

Most of the dehumidifiers I’ve used have replaceable filters. The replacements are often sold by the unit manufacturers, but you should always check the availability.

Meanwhile, there are also some that use washable filters. This is more cost-efficient, and you no longer have to worry about availability.


Not all homeowners have the luxury of space in their garage. If you’re one of them, you should always check the unit’s dimensions.

The good thing is that you can find dehumidifiers with small footprints. It compensates for the device’s height, so more water can still be collected per day.

✔️Additional features

Aside from the mentioned features, you can also look for additional functionalities. This will add value to your purchase as well as to the efficacy of the unit in your garage.

  • Timer. Dehumidifiers with built-in timers will let you operate the unit within a specific timeframe. This way, you don’t have to supervise the unit all the time, and you can leave it running overnight if need be.
  • Auto-defrost. An auto-defrost feature is indispensable if you’re going to operate the dehumidifier in low-temperature areas. It will prevent ice from forming inside the unit so that it won’t block the airflow.
  • Auto shutoff. An auto-shutoff feature is a safety feature that will prevent the unit from overflowing (when using the manual drain) and overheating.
  • LCD screen. An LCD screen will display the humidity level (current and target), timer, temperature, and more. This will let you monitor the dehumidifier easier. Some would even come with intelligent functions and mobile phone connectivity.
  • Variable fan speed. A variable fan speed will let you adjust the drying speed based on the humidity level in your garage. This will also help you save electricity, not to mention that you can also control the unit’s noise level.

✔️Price range

Lastly, you should decide the budget you’ll allot for the best humidifier for garage use. While dirt-cheap options are convenient, these units rarely last, and accuracy are dodgy.

Still, you don’t have to spend a fortune just to get a dehumidifier that works. The key here is finding the right balance between quality, capacity, and cost.
