LEVOIT LAP-C511S-WUS

At the standardized usage ENERGY STAR assumes, the LEVOIT LAP-C511S-WUS consumes 194 kWh a year — about $36 at the U.S. average electricity rate ($2.96 a month). Efficiency-wise it's unremarkable in a good way: within 31% of the median certified air purifier (rank 133 of 225). The same unit costs $25 a year in Nevada but $102 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 (225 models), so rankings shift more with each data refresh.
