in the United States

A day of nonstop drying means 127.51 pints of water, about 15.9 gallons, for some 18.5 kWh. At the average home electricity price in the United States, the Ultra V155 costs $3.39 to run that day.

Thirty days like that would use about 555 kWh, or $102. That’s nonstop running at the test conditions. Once the house reaches its humidity setting, the unit shuts off.
