MOISWELL Defender ME-7S

The MOISWELL Defender ME-7S is certified at 285 kWh per year, roughly $54 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 17% under the median dehumidifier, ranked 179 of 481. The same unit costs $35 a year in North Dakota but $133 in Hawaii — electricity rates, not the appliance, make the difference.
