Alen BreatheSmart 75i_V2

At the standardized usage ENERGY STAR assumes, the Alen BreatheSmart 75i_V2 consumes 304 kWh a year — about $56 at the U.S. average electricity rate ($4.65 a month). It sits near the bottom of the certified table — using 105% more than the median air purifier (rank 190 of 225) — so the state you live in matters more than usual.
