DREAME CVA10B

At the standardized usage ENERGY STAR assumes, the DREAME CVA10B consumes 32 kWh a year — about $5.87 at the U.S. average electricity rate ($0.49 a month). That puts it in the most efficient tenth of every certified air purifier — 78% less electricity than the median, ranked 2 of 225. The same unit costs $4.20 a year in Nevada but $17 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.
