Dreo Home DR-HAP009AS

At the standardized usage ENERGY STAR assumes, the Dreo Home DR-HAP009AS consumes 159 kWh a year — about $30 at the U.S. average electricity rate ($2.49 a month). That's close to the middle of the certified pack — about 7% above the median air purifier, ranked 117 of 214. The same unit costs $20 a year in North Dakota but $74 in Hawaii — electricity rates, not the appliance, make the difference. Note the certified pool here is small (214 models), so rankings shift more with each data refresh.
