KESNOS CTH30E

The KESNOS CTH30E is certified at 117 kWh per year, roughly $21 at the national average — though seasonal use means your real bill lands in a few months, not twelve. That puts it in the most efficient tenth of every certified dehumidifier — 65% less electricity than the median, ranked 19 of 519. The same unit costs $15 a year in Nevada but $62 in Hawaii — electricity rates, not the appliance, make the difference.
