Waykar CHWA150PE
Under the DOE test basis, the Waykar CHWA150PE draws 499 kWh — about $92 at the U.S. average rate, concentrated in the months you actually run it. Efficiency-wise it's unremarkable in a good way: within 48% of the median certified dehumidifier (rank 363 of 519). The same unit costs $65 a year in Nevada but $263 in Hawaii — electricity rates, not the appliance, make the difference.
