How much does it cost to run an air purifier in Hawaii?

$69/yr · median certified model

Hawaii is the extreme case for U.S. electricity costs: 46.6¢/kWh, roughly 2.5× the national average. The median certified air purifier costs about $69 a year here — the same appliance would cost $28 at national-average rates. In this rate environment, the gap between an efficient and an inefficient air purifier is often larger than the appliance's purchase-price difference over its lifetime.

Hawaii sits at rank 51 of 51 — near the very top of the cost table for an air purifier. At local rates, certified models span $14 (Blueair 4612522000) to $228 (Fellowes Aeramax SV) per year — $214 of annual headroom that depends entirely on which unit you buy. For reference, the national extremes are North Dakota (12.3¢/kWh) and Hawaii (46.6¢/kWh); the same median air purifier would cost $18 and $69 a year there.
