Dehumidifier Efficiency and Input-Power Comparison
Compare normalized IEF data and rough input-power scenarios
Quick Answer
Raw watts do not measure dehumidifier efficiency because products remove different amounts of moisture under different conditions. Use Integrated Energy Factor (liters of water removed per kilowatt-hour) for comparable certified products; higher IEF indicates more moisture removed per unit of electricity. The input-power examples below are rough cost scenarios, not efficiency rankings.

Formula
Cost = (watts ÷ 1,000) × hours used × electricity rate per kWh.
Data used
Calculator results use user-entered wattage and usage hours, combined with residential electricity rates for the selected U.S. state or the rate entered from a utility bill.
