MOISWELL Defender H150

Under the DOE test basis, the MOISWELL Defender H150 draws 530 kWh — about $100 at the U.S. average rate, concentrated in the months you actually run it. It sits near the bottom of the certified table — using 55% more than the median dehumidifier (rank 450 of 481) — so the state you live in matters more than usual. The same unit costs $65 a year in North Dakota but $247 in Hawaii — electricity rates, not the appliance, make the difference.
