Model
Midea MDUDA-22AEN8-BA7
Rank #127 means 126 of the 519 dehumidifier models we track cost less to run each year; the 10th efficiency percentile means it uses less energy for its size than 10% of those models.
What does the Midea MDUDA-22AEN8-BA7 cost to run per year?
Ranking #127 of 519, the Midea MDUDA-22AEN8-BA7 is in the cheaper half of its class to run, at about $51 a year. Normalized for capacity, it beats only 10% of dehumidifier models we track, one of the weaker efficiency results we track for the class. 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 MDA22C4BWWCM at $51/yr runs a little cheaper and the Midea MDUDA-22AEN8-BA7N at $51/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 MDUDA-22AEN8-BA7's $51/yr adds up to roughly $408 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BDM22WCDA.
By the numbers
The Midea MDUDA-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 $51/yr, here is what the Midea MDUDA-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 MDUDA-22AEN8-BA7 costs about $510. That is roughly $130 less than the class median, which would run closer to $640 over the same ten years.
How the Midea MDUDA-22AEN8-BA7 compares
The dehumidifier class we track runs from $19 to $521 a year. At $51/yr, it runs about $13 a year cheaper than the class median of $64, and it is about $32 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.27 pints/day, the Midea MDUDA-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). 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 MDUDA-22AEN8-BA7 cheap to run?
Yes, relatively. At $51 a year it ranks #127 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Midea MDUDA-22AEN8-BA7 cost per month?
Roughly $4.27/mo, spreading the $51/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 276 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $51 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MDUDA-22AEN8-BA7 for its size?
10th percentile once size is factored in, a fairly typical result for the class.
