Honeywell HPA125

The Honeywell HPA125's certified consumption is 72 kWh per year, which prices out to about $13 at the national average rate — your hours of use scale that directly. That's 51% less than the median certified air purifier, placing it comfortably in the efficient third of the field (34 of 225). The same unit costs $9.44 a year in Nevada but $38 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.
