Model
Midea MAD50P1AWS-A
Rank #437 means 436 of the 519 dehumidifier models we track cost less to run each year; the 56th efficiency percentile means it uses less energy for its size than 56% of those models.
What does the Midea MAD50P1AWS-A cost to run per year?
The Midea MAD50P1AWS-A costs about $97 a year to run, sitting well up the cheapest-to-run leaderboard, rank #437 of 519. Its 56th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. Its IEF of 2.01 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Midea MAD50C1AWS-A at $97/yr runs a little cheaper and the Midea MDUDP-50AEN8-BB0 at $97/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dehumidifier typically stays in service for somewhere around 8 years; over that span, the Midea MAD50P1AWS-A's $97/yr adds up to roughly $776 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MAD50P1AWS-A normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $97/yr, here is what the Midea MAD50P1AWS-A adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Midea MAD50P1AWS-A costs about $970. That is roughly $330 more than the class median, which would run closer to $640 over the same ten years.
How the Midea MAD50P1AWS-A compares
The dehumidifier class we track runs from $19 to $521 a year. At $97/yr, it runs about $33 a year above the class median of $64, and it is about $78 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.74 pints/day, the Midea MAD50P1AWS-A is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and larger dehumidifier models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Beyond size, its IEF of 2.01, above the class median of 2.01, is the class's own efficiency yardstick, integrated energy factor, and it is what separates two similarly sized models with different running costs.
- Integrated Energy Factor (IEF). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Midea MAD50P1AWS-A cheap to run?
Not especially. At $97 a year it ranks #437 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Midea MAD50P1AWS-A cost per month?
Roughly $8.12/mo, spreading the $97/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 525 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $97 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MAD50P1AWS-A for its size?
56th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
