Air Movement in Crawl Spaces and Basements

The Importance of Air Movement in Your Home

A key factor to consider when choosing a dehumidifier is the amount of air movement needed to distribute dry air throughout the entire crawl space or basement.

Most free-standing dehumidifiers tend to recirculate the air immediately surrounding them, creating a zone of warm, lower-relative-humidity. This often leads to a dehumidifier prematurely shutting down its cooling cycle and then starting up again a short time later — not only is this inefficient, but it delivers poor moisture removal.

The goal of encapsulating and conditioning a crawl space or basement is to protect your foundation and home.

  • Ensure your dehumidifier is able to extract moisture in the air from all spaces of your crawl space or basement, whether this is ducting the unit or placing it in a central location.
  • Determine the size, placement and ducting options of your dehumidifier, based on the size of your crawl space or basement as well as the number of pillars or sections within them.
