Model
Midea MAD22S1AWWT
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 MAD22S1AWWT cost to run per year?
Do the math and the Midea MAD22S1AWWT's $51/yr puts it at rank #127 of 519, on the cheaper side of the class. Adjusted for size, it is only more efficient than 10% of dehumidifier models we track, so its headline cost is mostly a function of its 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 Frigidaire FHDD2233Y1 at $51/yr runs a little cheaper and the Midea MAD22S1BWWT 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 MAD22S1AWWT'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 MAD22S1AWWT 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 MAD22S1AWWT 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 MAD22S1AWWT 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 MAD22S1AWWT 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 MAD22S1AWWT 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. Beyond size, its IEF of 1.7, below 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 MAD22S1AWWT 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 MAD22S1AWWT 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 MAD22S1AWWT for its size?
10th percentile once size is factored in, a fairly typical result for the class.
