The 6 Best Crawl Space Dehumidifiers As Of December, 2021 (And 12 Other Models)

Our list made of the latest crawl space dehumidifiers includes only dehumidifiers that satisfy these specifications:

  • Crawl-space dehumidifiers, unlike regular basement models, go underneath your house and sport a number of features that make them a better fit for tight crawl spaces: They are horizontal-shaped, obviously include a drain or pump drain and tend to have a higher pint-per-day dehumidification rate, up to 120 pints per day. It is preferable to seal your vents when in use.
  • Given that crawl spaces under houses can vary in height, we chose to use the cubic feet coverage value, allowing you to estimate your crawl space area by multiplying its width, length, and height.
  • The crawl-space dehumidifiers listed here all obey a maximum height of 3 feet.
  • Most come with wall-mounting brackets, some are stackable.
