Dreo Home DR-HAP007S
The Dreo Home DR-HAP007S's certified consumption is 140 kWh per year, which prices out to about $26 at the national average rate — your hours of use scale that directly. Efficiency-wise it's unremarkable in a good way: within 5% of the median certified air purifier (rank 104 of 225). The same unit costs $18 a year in Nevada but $74 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.
