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

$51/yr · median certified model

Electricity in California is genuinely expensive — 34.7¢/kWh, 89% above the national average — so the median certified air purifier costs about $51 a year, and efficiency differences between models turn into real money.

California sits at rank 50 of 51 — near the very top of the cost table for an air purifier. At local rates, certified models span $10 (Blueair 4612522000) to $170 (Fellowes Aeramax SV) per year — $160 of annual headroom that depends entirely on which unit you buy. 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.
