Best Dehumidifiers for Basements, Crawl Spaces, and Other Damp Areas

Consider how damp and how big your space is

During the season when humidity is high, a dehumidifier in a damp basement can be running almost all the time. So it’s good to know that tougher energy standards enacted in recent years have made dehumidifiers cheaper to operate. In fact, those that qualify for the Energy Star designation are 15 percent more efficient than those that don’t and can save you $100 in energy costs over the life of the unit. And no matter the size, every dehumidifier in Consumer Reports’ latest tests scored a Very Good or Excellent for energy efficiency.

We test dehumidifiers with small (rated to remove 25 to 40 pints of moisture per day), medium (45 to 50 pints per day), and large (75 pints per day) capacities. The size you buy depends on the area of the space that needs to be dehumidified and how damp or wet it is. You might also want to opt for a model with a large-capacity tank, so you don’t have to empty it as often.

All but two of the dehumidifiers in our tests excelled at combating dampness. Where they differed was in the accuracy of their humidistat, their performance in a cool room, and their noise level.
