Model
Midea MDUDP-40AEN8-BB0
Rank #330 means 329 of the 519 dehumidifier models we track cost less to run each year; the 79th efficiency percentile means it uses less energy for its size than 79% of those models.
What does the Midea MDUDP-40AEN8-BB0 cost to run per year?
The Midea MDUDP-40AEN8-BB0 costs about $80 a year to run, more than most of the 519 dehumidifier models we track; it ranks #330. Capacity-normalized, it ranks ahead of 79% of dehumidifier models we track, a reasonably strong result for the class. At a IEF of 2.01, its integrated energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Santa Fe 4047100 at $78/yr runs a little cheaper and the Pelonis PAD40C1AWTS at $80/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 MDUDP-40AEN8-BB0's $80/yr adds up to roughly $640 in electricity alone, before purchase price or repairs.
Also sold as: Pelonis PAD40C1AWTS.
By the numbers
The Midea MDUDP-40AEN8-BB0 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 $80/yr, here is what the Midea MDUDP-40AEN8-BB0 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 MDUDP-40AEN8-BB0 costs about $800. That is roughly $160 more than the class median, which would run closer to $640 over the same ten years.
How the Midea MDUDP-40AEN8-BB0 compares
The dehumidifier class we track runs from $19 to $521 a year. At $80/yr, it runs about $16 a year above the class median of $64, and it is about $61 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 41.79 pints/day, the Midea MDUDP-40AEN8-BB0 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). IEF measures liters of water removed per kilowatt-hour; a higher IEF means less energy per pint of moisture removed for a given capacity.
- Water removal capacity (pints/day). A dehumidifier rated to remove more pints per day is built for a larger space or a more humid room, and generally draws more power to do it.
- Humidistat accuracy. A unit with a more precise humidistat cycles the compressor off once the target humidity is reached, rather than running continuously.
Common questions
Is the Midea MDUDP-40AEN8-BB0 cheap to run?
Its $80/yr running cost, rank #330 of 519, is above what most dehumidifier models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Midea MDUDP-40AEN8-BB0 cost per month?
About $6.65 a month, which is the $80 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 430 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $80 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MDUDP-40AEN8-BB0 for its size?
79th 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.
