Model
Aeric AERD501P
Rank #355 means 354 of the 519 dehumidifier models we track cost less to run each year; the 89th efficiency percentile means it uses less energy for its size than 89% of those models.
What does the Aeric AERD501P cost to run per year?
At about $93 a year, the Aeric AERD501P costs more to run than most dehumidifier models we track, rank #355 of 519. Its size-adjusted efficiency percentile of 89 sits well above the class median, a clearly above-average efficiency result. The IEF figure of 2.1 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Multistar MDHP5079US* at $93/yr runs a little cheaper and the Aeric AERD501PF at $93/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 Aeric AERD501P's $93/yr adds up to roughly $744 in electricity alone, before purchase price or repairs.

By the numbers
The Aeric AERD501P 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 $93/yr, here is what the Aeric AERD501P adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Aeric AERD501P costs about $930. That is roughly $290 more than the class median, which would run closer to $640 over the same ten years.
How the Aeric AERD501P compares
The dehumidifier class we track runs from $19 to $521 a year. At $93/yr, it runs about $29 a year above the class median of $64, and it is about $74 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.32 pints/day, the Aeric AERD501P 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, putting it squarely in the middle of the class on the size lever that drives most of the cost. Beyond size, its IEF of 2.1, 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 Aeric AERD501P cheap to run?
Its $93/yr running cost, rank #355 of 519, is above what most dehumidifier models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Aeric AERD501P cost per month?
About $7.76 a month, which is the $93 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: 502 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $93 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Aeric AERD501P for its size?
89th 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.
