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

$48/yr · median certified model

Electricity in Connecticut is genuinely expensive — 32.2¢/kWh, 71% above the national average — so the median certified air purifier costs about $48 a year, and efficiency differences between models turn into real money.

Connecticut sits at rank 49 of 51 — near the very top of the cost table for an air purifier. Model choice matters as much as geography: at Connecticut rates the most efficient certified model (Blueair 4612522000) costs $9.67 a year while the most power-hungry (Fellowes Aeramax SV) costs $158 — a spread of $148 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.
