A good rule of thumb for picking out a humidifier for a crawl space is the smaller the space is, the smaller the dehumidifier should be. For a crawl space that’s about 300 square feet, you’ll want a 20-30-pint sized dehumidifier. For a 500 square foot space, you’ll want a 25-40-pint dehumidifier.

How do I choose a crawl space dehumidifier?

To ensure proper humidity control, we recommend sizing your project by cubic volume rather than square area.

Be sure to include any offset spaces and areas under adjacent rooms in your calculations.

How do you know what size dehumidifier to buy?

Other factors can influence the humidity of the room, so consider the following when sizing a dehumidifier:

1. If your home is in a humid climate, add 10 pints to the recommended capacity.
