Midea MAD50PS1BWT-C: running cost
ENERGY STAR certifies the Midea MAD50PS1BWT-C at 520 kWh/yr, one of the more expensive models in its category to run for its category.
That $98 is priced at 18.8¢/kWh, the average of all 51 state rates this site tracks. Your own state's rate is one click away.
Efficient, or not, for a dehumidifier
The category average is 378 kWh/yr; this model runs 37.6% above it, ranking 446 of 546 dehumidifiers tracked here for running cost. That average is drawn from all 546 dehumidifiers ENERGY STAR currently certifies, not an outside number, a $27/year gap from this model at the national rate. Full sourcing is in the sourcing notes.
Right next to it on the list
A rank or two either side of the Midea MAD50PS1BWT-C: Midea MAD50PS1BWBL ($98/yr, 520 kWh/yr), then Midea MAD50PS1CWBL ($98/yr, 520 kWh/yr).
Within the Midea lineup
Ranked 38 of Midea's 44 certified dehumidifiers, this sits between the MAD20S1QWT ($47/yr, the brand's cheapest) and the MDUDP-50AEN8-BB0 ($99/yr, its priciest).
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 MAD50PS1BWT-C 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.
If you're keeping it
A dehumidifier like the Midea MAD50PS1BWT-C 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.
Where this number comes from
Ranked 446 of 546, the Midea MAD50PS1BWT-C 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. The 520 kWh/yr figure is ENERGY STAR's own certification, not a wattage estimate; exact dataset IDs are on the data sources page.
