Dreo Home DR-HAP009AS
At the standardized usage ENERGY STAR assumes, the Dreo Home DR-HAP009AS consumes 159 kWh a year — about $29 at the U.S. average electricity rate ($2.43 a month). That's close to the middle of the certified pack — about 7% above the median air purifier, ranked 120 of 225. The same unit costs $21 a year in Nevada but $84 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.
