Dreo Home DR-HAP003S

The Dreo Home DR-HAP003S's certified consumption is 282 kWh per year, which prices out to about $53 at the national average rate — your hours of use scale that directly. It sits near the bottom of the certified table — using 91% more than the median air purifier (rank 170 of 214) — so the state you live in matters more than usual. The same unit costs $35 a year in North Dakota but $131 in Hawaii — electricity rates, not the appliance, make the difference. Note the certified pool here is small (214 models), so rankings shift more with each data refresh.
