MegaLight AP-HCE99-WT

At the standardized usage ENERGY STAR assumes, the MegaLight AP-HCE99-WT consumes 89 kWh a year — about $17 at the U.S. average electricity rate ($1.40 a month). That's 40% less than the median certified air purifier, placing it comfortably in the efficient third of the field (44 of 214). The same unit costs $11 a year in North Dakota but $41 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria. Note the certified pool here is small (214 models), so rankings shift more with each data refresh.
