Model
Midea MDUDP-50AEN8-BB0B
Rank #411 means 410 of the 519 dehumidifier models we track cost less to run each year; the 73rd efficiency percentile means it uses less energy for its size than 73% of those models.
What does the Midea MDUDP-50AEN8-BB0B cost to run per year?
At $96 a year to run, the Midea MDUDP-50AEN8-BB0B runs more expensively than most models in its class, ranking #411 of 519 dehumidifier models we track. Its 73th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. 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 Waykar CTH150PB at $96/yr runs a little cheaper and the Ge ADSE50X**# at $96/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-50AEN8-BB0B's $96/yr adds up to roughly $768 in electricity alone, before purchase price or repairs.
By the numbers
The Midea MDUDP-50AEN8-BB0B 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 $96/yr, here is what the Midea MDUDP-50AEN8-BB0B 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-50AEN8-BB0B costs about $960. That is roughly $320 more than the class median, which would run closer to $640 over the same ten years.
How the Midea MDUDP-50AEN8-BB0B compares
The dehumidifier class we track runs from $19 to $521 a year. At $96/yr, it runs about $32 a year above the class median of $64, and it is about $77 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.74 pints/day, the Midea MDUDP-50AEN8-BB0B is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, among dehumidifier models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. The IEF of 2.01 on this model, above 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 MDUDP-50AEN8-BB0B cheap to run?
Not especially. At $96 a year it ranks #411 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Midea MDUDP-50AEN8-BB0B cost per month?
Roughly $8.01/mo, spreading the $96/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 518 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $96 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MDUDP-50AEN8-BB0B for its size?
73rd 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.
