DREAME CVF20B
The DREAME CVF20B's certified consumption is 149 kWh per year, which prices out to about $27 at the national average rate — your hours of use scale that directly. Efficiency-wise it's unremarkable in a good way: within 1% of the median certified air purifier (rank 114 of 225). The same unit costs $20 a year in Nevada but $79 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.
