ALORAIR Helios D35

The ALORAIR Helios D35 is certified at 274 kWh per year, roughly $50 at the national average — though seasonal use means your real bill lands in a few months, not twelve. That's 19% less than the median certified dehumidifier, placing it comfortably in the efficient third of the field (122 of 519). The same unit costs $36 a year in Nevada but $144 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
