WOOZOO APF-20
At the standardized usage ENERGY STAR assumes, the WOOZOO APF-20 consumes 150 kWh a year — about $28 at the U.S. average electricity rate ($2.36 a month). Efficiency-wise it's unremarkable in a good way: within 1% of the median certified air purifier (rank 110 of 214). Where you live moves the bill from $19 a year in North Dakota to $70 in Hawaii. Note the certified pool here is small (214 models), so rankings shift more with each data refresh.
