Honeywell HPA4200B
At the standardized usage ENERGY STAR assumes, the Honeywell HPA4200B consumes 137 kWh a year — about $26 at the U.S. average electricity rate ($2.15 a month). That's close to the middle of the certified pack — about 7% under the median air purifier, ranked 100 of 214. The same unit costs $17 a year in North Dakota but $64 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.
