Model
Midea MAD35S1CWWT
Rank #323 means 322 of the 519 dehumidifier models we track cost less to run each year; the 63rd efficiency percentile means it uses less energy for its size than 63% of those models.
What does the Midea MAD35S1CWWT cost to run per year?
Do the math and the Midea MAD35S1CWWT's $71/yr puts it at rank #323 of 519, on the pricier side of the class. Adjusted for size, it is more efficient than 63% of dehumidifier models we track, a solidly above-average result. 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 Midea MAD35S1BWWT at $71/yr runs a little cheaper and the Midea MDUDA-35AEN8-BB0F at $71/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 MAD35S1CWWT's $71/yr adds up to roughly $568 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BDM36WCDA.
By the numbers
The Midea MAD35S1CWWT 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 $71/yr, here is what the Midea MAD35S1CWWT 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 MAD35S1CWWT costs about $710. That is roughly $70 more than the class median, which would run closer to $640 over the same ten years.
How the Midea MAD35S1CWWT compares
The dehumidifier class we track runs from $19 to $521 a year. At $71/yr, it runs about $7 a year above the class median of $64, and it is about $52 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 36.39 pints/day, the Midea MAD35S1CWWT 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. Beyond size, its IEF of 2.01, above 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 MAD35S1CWWT cheap to run?
Not especially. At $71 a year it ranks #323 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 MAD35S1CWWT cost per month?
Roughly $5.92/mo, spreading the $71/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 383 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $71 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MAD35S1CWWT for its size?
63rd 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.
