How to Choose the Best Dehumidifier for the Garage?
Choosing the best garage dehumidifier isn’t a matter of buying the most expensive or the largest model. The most suitable dehumidifier for your garage comes down to your specific requirements. There are several key factors to consider before purchasing your garage dehumidifier.
Size of Your Garage
If you have an unusually large garage, a powerful dehumidifier is likely to be the best choice for removing moisture from the air. Many garages with damp air need a dehumidifier to operate around the clock to ensure the air quality remains high, putting a strain on the working components.
To avoid overheating and potential damage to the unit, it is vital to purchase a dehumidifier that can remove moisture from large spaces.
During testing, we noted several models have auto shut-off features when the tank is full, so there is no risk of flooding. You can also use continuous drainage hoses if the water container is too heavy for manual emptying.
General or Localized Moisture
Even if your garage is large, a smaller and less expensive dehumidifier may be the right choice for your space. Some garages have localized moisture issues that gather at particular points such as windows or gaps around the door.
In this scenario, you may be able to place a portable dehumidifier at the damp problem site and move it to another area. Although this may take more effort when moving the unit around your garage, it may work out to be a less expensive solution to a moisture problem.
We found the lightweight design of many dehumidifiers made it easy to transport them to different locations, and they are powerful enough to deal with damp air even in reasonably large garage spaces. Models with wheels were incredibly convenient for moving around the area.
Dehumidifier Noise Level
Most dehumidifiers have a relatively quiet noise operating level. However, if you spend a considerable amount of time in your garage or invite friends over for DIY projects, you may prefer a near-silent model.
A noisy dehumidifier running in the background could become irritating and interrupt the conversation, but several ultra-quiet models are barely audible.
Final Verdict: Our Top Choice
There are several excellent garage dehumidifiers, and you may find the most suitable model for your needs isn’t the top pick on our list. However, for overall build quality, convenience, and efficient moisture removal, we couldn’t overlook the Black+Decker BDT50PWTB Dehumidifier as the best garage dehumidifier on the market.
The auto defrost function is essential if you live in areas where it gets particularly cold in winter, and the 24-hour on/off timer is a significant cost saving feature. Despite its powerful performance, the unit design is compact, and the intuitive top-mounted LED control panel is easy to use. Don’t hesitate to invest in the best and get this garage dehumidifier today.
