NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Shopping for a new one
Running above the category average, $97/year is exactly the kind of number that makes a newer, more efficient model pay for itself faster.
