Model
Midea MDUDP-22AEN8-BA7
Rank #136 means 135 of the 519 dehumidifier models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the Midea MDUDP-22AEN8-BA7 cost to run per year?
Among the 519 dehumidifier models we track, the Midea MDUDP-22AEN8-BA7 sits in the below-average-cost group, rank #136, at roughly $52 a year. Its size-adjusted efficiency percentile of 7 means the low running cost, where it exists, is driven almost entirely by capacity rather than efficiency. The IEF figure of 1.7 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 MAD22S1WWT at $52/yr runs a little cheaper and the Seasons SD22CA1 at $52/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-22AEN8-BA7's $52/yr adds up to roughly $416 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MDUDP-22AEN8-BA7 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 $52/yr, here is what the Midea MDUDP-22AEN8-BA7 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-22AEN8-BA7 costs about $520. That is roughly $120 less than the class median, which would run closer to $640 over the same ten years.
How the Midea MDUDP-22AEN8-BA7 compares
The dehumidifier class we track runs from $19 to $521 a year. At $52/yr, it runs about $12 a year cheaper than the class median of $64, and it is about $33 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.31 pints/day, the Midea MDUDP-22AEN8-BA7 is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and smaller dehumidifier models generally cost less to run for the same job, all else being equal. The IEF of 1.7 on this model, below the class median of 2.01, measures integrated energy factor; it is the number to compare directly against another model's IEF if capacity is similar.
- 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-22AEN8-BA7 cheap to run?
Yes. Its $52/yr running cost puts it at rank #136 of 519, below what most dehumidifier models we track cost to run.
How much does the Midea MDUDP-22AEN8-BA7 cost per month?
About $4.3 a month, which is the $52 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: 278 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $52 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MDUDP-22AEN8-BA7 for its size?
7th percentile once size is factored in, a fairly typical result for the class.
