Midea W
At the standardized usage ENERGY STAR assumes, the Midea W consumes 259 kWh a year — about $48 at the U.S. average electricity rate ($3.96 a month). That's close to the middle of the certified pack — about 75% above the median air purifier, ranked 169 of 225. The same unit costs $34 a year in Nevada but $137 in Hawaii — electricity rates, not the appliance, make the difference. Note the certified pool here is small (225 models), so rankings shift more with each data refresh.
