ALROCKET MK01A

At the standardized usage ENERGY STAR assumes, the ALROCKET MK01A consumes 33 kWh a year — about $6.21 at the U.S. average electricity rate ($0.52 a month). That puts it in the most efficient tenth of every certified air purifier — 78% less electricity than the median, ranked 4 of 214. The same unit costs $4.08 a year in North Dakota but $15 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.
