CleanForce CP-Rainbow

At the standardized usage ENERGY STAR assumes, the CleanForce CP-Rainbow consumes 309 kWh a year — about $58 at the U.S. average electricity rate ($4.85 a month). Even among certified models it's on the thirsty end: 109% more electricity than the median air purifier, ranked 181 of 214. The same unit costs $38 a year in North Dakota but $144 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.
