Blueair Pure 411

At the standardized usage ENERGY STAR assumes, the Blueair Pure 411 consumes 64 kWh a year — about $12 at the U.S. average electricity rate ($1.00 a month). Compared with the median certified air purifier, it uses 57% less electricity — rank 30 out of 214. The same unit costs $7.90 a year in North Dakota but $30 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.
