Midea MAD50PS1QWT-A against the category
That's 36.2% above the dehumidifier category average of 378 kWh/yr, and ranks 415 of 546 certified dehumidifiers for annual running cost, 1 being cheapest. The category average comes from every dehumidifier ENERGY STAR currently certifies (546 models), not an outside benchmark, about $26/year above that average at the national rate. See the methodology page.
What sits beside it in the ranking
Midea MAD50S1QWT-A ($97/yr, 515 kWh/yr) costs a little more to run than the Midea MAD50PS1QWT-A. Midea MAD50PS1BQGR ($97/yr, 515 kWh/yr) costs a little less.
Within the Midea lineup
Midea makes 44 ENERGY STAR certified dehumidifiers; this one ranks 31 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 MAD50PS1QWT-A 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 $97/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
At $97/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
Sourcing
Nothing here is estimated from a nameplate wattage; the 515 kWh/yr is ENERGY STAR's own certified figure for this model. Ranked 415 of 546, the Midea MAD50PS1QWT-A sits in the middle of the dehumidifier category, see the guide to why your state changes this number for the other half of the math.
