How much does it cost to run an air purifier in Maine?
$44/yr · median certified model
Electricity in Maine is genuinely expensive — 29.6¢/kWh, 61% above the national average — so the median certified air purifier costs about $44 a year, and efficiency differences between models turn into real money.
Only 3 jurisdictions cost more: Maine ranks 48 of 51 for running an air purifier. Model choice matters as much as geography: at Maine rates the most efficient certified model (Blueair 4612522000) costs $8.88 a year while the most power-hungry (Fellowes Aeramax SV) costs $145 — a spread of $136 every year. For reference, the national extremes are Nevada (13.1¢/kWh) and Hawaii (52.7¢/kWh); the same median air purifier would cost $19 and $78 a year there.
