Dehumidifiers: what they cost to run

Seasonal appliances concentrate their cost into a few months. On the DOE's standardized basis, the 481 certified dehumidifiers here span $20–$529 annually (median $65).

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.

How to read these numbers

The certified annual kWh comes from the DOE test basis for standardized annual runtime. Damp basements that run a unit year-round will exceed it; seasonal use will come in under. Full methodology and limitations →

Questions, answered with the data

How much does a dehumidifier cost to run per year?
The median ENERGY STAR certified dehumidifier costs about $65 a year at the U.S. average rate (18.8¢/kWh). Across all 481 certified models, costs range from $20 to $529.
How much electricity does a dehumidifier use?
Certified models use between 105 and 2,808 kWh per year (median 343). The certified annual kWh comes from the DOE test basis for standardized annual runtime. Damp basements that run a unit year-round will exceed it; seasonal use will come in under.
Where is a dehumidifier cheapest and most expensive to run?
North Dakota has the lowest residential rate (12.3¢/kWh), putting the median dehumidifier at $42 a year; Hawaii (46.6¢/kWh) is the most expensive at $160.
What makes one dehumidifier cheaper to run than another?
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.
