MaxLite AP215SF4B
At the standardized usage ENERGY STAR assumes, the MaxLite AP215SF4B consumes 144 kWh a year — about $26 at the U.S. average electricity rate ($2.20 a month). That's close to the middle of the certified pack — about 3% under the median air purifier, ranked 106 of 225. The same unit costs $19 a year in Nevada but $76 in Hawaii — electricity rates, not the appliance, make the difference.
