Lowest Operating Cost: Dehumidifiers

Ranked by estimate. Operating cost is an estimate, computed from each model's measured annual energy use at the EIA U.S. national-average residential electricity rate (18.56 ¢/kWh, March 2026). Your actual cost depends on your local utility rate and how you use the appliance.

The CONCETTA AS-CSJ72XK-2WT-OL ranks as the lowest-operating-cost dehumidifier in the dataset, with an estimated annual operating expense of $19.49 based on measured energy consumption of 105 kWh per year and the national-average electricity rate. This ranking reflects energy use alone and is limited to certified models; it does not account for payment or sponsorship arrangements that might otherwise influence placement.

Operating cost represents only one dimension of dehumidifier selection. Capacity, available features, reliability history, and purchase price all carry significant weight in the buying decision and are not factored into this energy-efficiency comparison. The lowest-operating-cost model may not be the best choice for all applications or users. This dataset functions as an energy-efficiency reference point—a spec-and-cost comparison tool—rather than a comprehensive buying recommendation. Consumers should evaluate the full range of specifications and costs alongside operating expenses to determine the best fit for their needs.
