Carrier RMAP-ST
The Carrier RMAP-ST's certified consumption is 158 kWh per year, which prices out to about $30 at the national average rate — your hours of use scale that directly. That's close to the middle of the certified pack — about 7% above the median air purifier, ranked 114 of 214. The same unit costs $20 a year in North Dakota but $74 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 (214 models), so rankings shift more with each data refresh.
