Coway Airmega AP-1523D
At the standardized usage ENERGY STAR assumes, the Coway Airmega AP-1523D consumes 219 kWh a year — about $40 at the U.S. average electricity rate ($3.35 a month). That's close to the middle of the certified pack — about 48% above the median air purifier, ranked 153 of 225. The same unit costs $29 a year in Nevada but $115 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.
