Honeywell HPA4300B
The Honeywell HPA4300B's certified consumption is 185 kWh per year, which prices out to about $34 at the national average rate — your hours of use scale that directly. Efficiency-wise it's unremarkable in a good way: within 25% of the median certified air purifier (rank 131 of 225). The same unit costs $24 a year in Nevada but $98 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.
