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.
