TCL W50D9P3-B

The TCL W50D9P3-B is certified at 516 kWh per year, roughly $95 at the national average — though seasonal use means your real bill lands in a few months, not twelve. It sits near the bottom of the certified table — using 53% more than the median dehumidifier (rank 413 of 519) — so the state you live in matters more than usual. The same unit costs $68 a year in Nevada but $272 in Hawaii — electricity rates, not the appliance, make the difference.
