How much does it cost to run a dehumidifier in Idaho?
$44/yr · median certified model
Residential electricity in Idaho runs 12.7¢/kWh — 33% under the U.S. average — putting the median certified dehumidifier at about $44 a year, versus $65 nationally.
That makes Idaho the #2 cheapest of the 51 U.S. jurisdictions for running a dehumidifier. Model choice matters as much as geography: at Idaho rates the most efficient certified model (CONCETTA AS-CSJ72XK-2WT-OL) costs $13 a year while the most power-hungry (Healthy Climate HCWHD#-130) costs $357 — a spread of $343 every year. For reference, the national extremes are North Dakota (12.3¢/kWh) and Hawaii (46.6¢/kWh); the same median dehumidifier would cost $42 and $160 a year there.
