How do I reduce the cost?

Shorten runtime, raise the humidity setpoint, or switch to a higher-efficiency unit to lower kWh consumption.

Additional Information

  • Result unit: kWh for usage plus USD for daily and billing-period cost.
  • Defaults assume a 700W whole-house dehumidifier and a 30-day month.
  • Energy use scales linearly with runtime and wattage; actual draw may vary with humidity and fan settings.
