Blueair Pure 211+

At the standardized usage ENERGY STAR assumes, the Blueair Pure 211+ consumes 350 kWh a year — about $64 at the U.S. average electricity rate ($5.35 a month). It sits near the bottom of the certified table — using 136% more than the median air purifier (rank 206 of 225) — so the state you live in matters more than usual. The same unit costs $46 a year in Nevada but $185 in Hawaii — electricity rates, not the appliance, make the difference. Note the certified pool here is small (225 models), so rankings shift more with each data refresh.
