The closest alternatives by cost
Sorted by running cost among dehumidifiers, one step cheaper is Frigidaire FHDP5033Y1 ($98/yr, 520 kWh/yr), and one step pricier is Midea MAD50PS1BWBL ($98/yr, 520 kWh/yr).
Same brand, different models
Midea makes 44 ENERGY STAR certified dehumidifiers; this one ranks 36 of 44 for running cost, between the brand's cheapest, the MAD20S1QWT at $47/yr, and its priciest, the MDUDP-50AEN8-BB0 at $99/yr.
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.
Weighing a replacement
The Midea MAD50PS1AWT-S runs above its category average. If the dehumidifier you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $98/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
$98/year to run is the predictable cost of the Midea MAD50PS1AWT-S; a protection plan covers the unpredictable one, a repair bill.
