Cooler temperatures in basements and crawlspaces create unique humidity control challenges. Often the only way to maintain the EPA’s recommended humidity levels for homes of 50% RH or less is by running a high capacity, high efficiency dehumidifier.
Most standard residential units remove 20 to 65 pints of water per day. However, most basements and crawlspaces are cooler than 80°F and a standard residential unit will not condition your space effectively. A large capacity dehumidifier may be needed to remove enough moisture to prevent mold, mildew or bacterial growth.
