Coway AP-1523D

The Coway AP-1523D's certified consumption is 219 kWh per year, which prices out to about $40 at the national average rate — your hours of use scale that directly. Efficiency-wise it's unremarkable in a good way: within 48% of the median certified air purifier (rank 154 of 225). The same unit costs $29 a year in Nevada but $115 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.
