Dehumidifiers: what they cost to run

Seasonal appliances concentrate their cost into a few months. On the DOE's standardized basis, the 519 certified dehumidifiers here span $19–$515 annually (median $62).

Capacity (pints/day) drives draw; the integrated energy factor (liters per kWh, higher is better) tells you which units wring more water out of each kilowatt-hour. Every figure on this page comes from ENERGY STAR's certified test data — the 105–2,808 kWh/yr range you see is measured, not estimated.

Median cost: $62/yr
Cheapest model: $19/yr
Priciest model: $515/yr
