Waykar CHWA120E

The Waykar CHWA120E is certified at 360 kWh per year, roughly $68 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 5% above the median dehumidifier, ranked 252 of 481. The same unit costs $44 a year in North Dakota but $168 in Hawaii — electricity rates, not the appliance, make the difference.
