Lifespan
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.
Is it worth replacing?
Efficient as certified dehumidifiers go, $42/year is a reasonable baseline if you're comparing what else is on the market.
