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, $52/year is a reasonable baseline if you're comparing what else is on the market.
Compare current ENERGY STAR certified dehumidifiers before buying.
If you're keeping it
A dehumidifier like the Midea MAD22S1BWWT is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
