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

$42/yr · median certified model

Electricity in Maine is genuinely expensive — 28.4¢/kWh, 51% above the national average — so the median certified air purifier costs about $42 a year, and efficiency differences between models turn into real money.

Maine ranks 46 of 51 jurisdictions for air purifier running costs — solidly mid-table. Model choice matters as much as geography: at Maine rates the most efficient certified model (Blueair 4612522000) costs $8.53 a year while the most power-hungry (Fellowes Aeramax SV) costs $139 — a spread of $131 every year. 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.
