Wood’s has several dehumidifiers suitable for use in crawl spaces and house foundations. In most cases, a compressor dehumidifier is the best choice. However, if you need to use it in lower temperatures, you might want to choose an adsorption dehumidifier. In crawl spaces and house foundations it is important with sufficient air circulation. When the air circulated you’ll make sure that the entire area is dehumidified, and not only the close proximity of the dehumidifier. A dehumidifier with a powerful airflow will dry the entire area quickly and efficiently, and eliminate the risk of damp and mould. Keep the relative humidity level between 50% and 60% to keep moisture, damp, mildew and mould at a safe distance.

Dehumidifiers suitable for crawl spaces and house foundations:

Dehumidifiers for crawl spaces


  • Seal the valves to avoid the unnecessarily humid air in the crawl space.
  • Place the dehumidifier as central as possible.
  • Make a stone curb for drainage.
  • Complete with a crawl space hygrometer to keep an eye on moisture level from above the house.
