How to lower the cost of running a dehumidifier

Dehumidifiers work like small air conditioners, using a compressor to condense moisture out of the air. Most home units draw 300–700W depending on capacity, and the humidistat switches the compressor off once the room reaches the target humidity. Basements in humid climates may need several hours a day in summer. ENERGY STAR models remove noticeably more water per kWh.

  • Set the humidistat to 45–50% — lower settings make it run much longer for little benefit.
  • Keep doors and windows closed in the room being dehumidified.
  • Clean the filter and coils regularly so the compressor works efficiently.
