Model
Midea MDUDMB-35AEN8-BB0F
Rank #293 means 292 of the 519 dehumidifier models we track cost less to run each year; the 57th efficiency percentile means it uses less energy for its size than 57% of those models.
What does the Midea MDUDMB-35AEN8-BB0F cost to run per year?
At $70 a year to run, the Midea MDUDMB-35AEN8-BB0F sits close to the middle of its class on cost, ranking #293 of 519 dehumidifier models we track. Its 57th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. The IEF figure of 2.01 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Midea MC35MSKBA3RCM at $70/yr runs a little cheaper and the Gasbye DryPrime-35-BP at $70/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 MDUDMB-35AEN8-BB0F's $70/yr adds up to roughly $560 in electricity alone, before purchase price or repairs.
Also sold as: Midea MAD35S1QGR-A.
By the numbers
The Midea MDUDMB-35AEN8-BB0F 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 $70/yr, here is what the Midea MDUDMB-35AEN8-BB0F 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 MDUDMB-35AEN8-BB0F costs about $700. That is roughly $60 more than the class median, which would run closer to $640 over the same ten years.
How the Midea MDUDMB-35AEN8-BB0F compares
The dehumidifier class we track runs from $19 to $521 a year. At $70/yr, it runs about $6 a year above the class median of $64, and it is about $51 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 35.82 pints/day, the Midea MDUDMB-35AEN8-BB0F is a mid-size dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. Its IEF of 2.01, above the class median of 2.01, reflects integrated energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 MDUDMB-35AEN8-BB0F cheap to run?
It is about average. At $70 a year it ranks #293 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Midea MDUDMB-35AEN8-BB0F cost per month?
Roughly $5.85/mo, spreading the $70/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 378 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $70 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MDUDMB-35AEN8-BB0F for its size?
57th percentile once size is factored in, a fairly typical result for the class.
