How this list is built: every entry comes straight from the ENERGY STAR certified-product dataset for dehumidifiers (519 models), ordered by certified annual kWh. 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.
