What Size Dehumidifier Do I Need for My Garage?

You can’t just pick a portable cordless small dehumidifier and expect it to cover the whole garage and remove moisture or humidity. You have to be selective in finding the right size of the garage dehumidifier.

You have to consider the actual size of your garage area, dampness or humidity level, and your dehumidifier’s capacity to find the right size of it.

Here are the suggestions for finding the appropriate size of your garage dehumidifier in short:

  • Choose a 65 pint to 70-pint dehumidifier for a 600-800 square feet garage with 75% to 100% dampness. However, the 2020 and later versions of these devices will work fine with 45pint capacity due to their improved technology for the same conditions.
  • If the dampness is anywhere from 50% to 75% in a 600-800 square feet garage area, choosing the dehumidifiers with 50-60 pint capacity should be fine.
  • If you have a smaller garage, you can even opt for dehumidifying devices with 30-40pint capacity. And for larger garages that go up to 1200 square feet or more, you have to find a machine with 70pint or more capacity to control humidity properly.

Will a Dehumidifier Work in a Cold Garage?

In cold areas, garage temperature may often shrink. Also, a cold garage often has a cooler environment that doesn’t brim with additional humidity. Most people wonder whether or not a dehumidifier will work in cold garages.

The good news is that many dehumidifiers will still work in cold garages, if not all. Yes, the regular compressor-run dehumidifiers will mostly remain ineffective in cold garages where the temperature is below 60°F (15°C).

However, manufacturers, these days use fan-based dehumidifiers, which can easily work even in the coldest space.
