What does the Midea MAD35S1QWT-A cost to run per year?

The Midea MAD35S1QWT-A costs about $70 a year to run, a fairly typical figure for the class; it ranks #293 of 519. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 57% of the models we track. At a IEF of 2.01, its integrated energy factor is the single figure that best explains how it earns its running-cost number.

Immediately around it on the leaderboard, the Midea MAD35S1QGR-A at $70/yr runs a little cheaper and the Midea MC35MSKBA3RCM at $70/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 MAD35S1QWT-A's $70/yr adds up to roughly $560 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $70/yr, here is what the Midea MAD35S1QWT-A adds up to before purchase price, water, or repairs enter the math.

1 year$70
5 years$350
10 years$700

Left running for a decade at today's US average rate, the Midea MAD35S1QWT-A costs about $700. That is roughly $60 more than the class median, which would run closer to $640 over the same ten years.

How the Midea MAD35S1QWT-A compares

The dehumidifier class we track runs from $19 to $521 a year. At $70/yr, it runs about $6 a year above the class median of $64, and it is about $51 a year more than the cheapest dehumidifier to run at $19.

What drives its running cost

At 35.82 pints/day, the Midea MAD35S1QWT-A 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). 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 MAD35S1QWT-A cheap to run?

Roughly, yes. Its $70/yr figure is close to the class median, ranking #293 of 519, neither a bargain nor a splurge on running cost.

How much does the Midea MAD35S1QWT-A cost per month?

About $5.85 a month, which is the $70 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: 378 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $70 a year. It covers electricity only, not the purchase price, water, or installation.

How efficient is the Midea MAD35S1QWT-A for its size?

57th percentile once size is factored in, a fairly typical result for the class.
