Midea KJ250G-Z43
At the standardized usage ENERGY STAR assumes, the Midea KJ250G-Z43 consumes 126 kWh a year — about $24 at the U.S. average electricity rate ($1.98 a month). Efficiency-wise it's unremarkable in a good way: within 15% of the median certified air purifier (rank 84 of 214). The same unit costs $16 a year in North Dakota but $59 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.
