Multistar MDHP5079US
The Multistar MDHP5079US is certified at 500 kWh per year, roughly $92 at the national average — though seasonal use means your real bill lands in a few months, not twelve. That's close to the middle of the certified pack — about 48% above the median dehumidifier, ranked 364 of 519. The same unit costs $66 a year in Nevada but $264 in Hawaii — electricity rates, not the appliance, make the difference.
