21 Whole-Home Dehumidifiers, Ranked by Running Cost

← All dehumidifier capacities

Whole-home (ducted) units are measured under a different test condition than portable dehumidifiers, so their pint ratings aren't directly comparable to the portable pages — that's why they're kept on their own page.

21 ENERGY STAR certified models, from about $77 to $514 a year to run at the US average electricity rate. See how we calculate running costs.

Estimated running cost = annual kWh × 18.31¢/kWh (July 2026 US average). Your own rate may be higher or lower — check your bill. ENERGY STAR figures are lab-test results; real-world use varies. This list includes discontinued and not-yet-sold certified models, and some brands are white-label relabels of the same unit.
