Model
Arecovas AR-DF002
Rank #110 means 109 of the 519 dehumidifier models we track cost less to run each year; the 22nd efficiency percentile means it uses less energy for its size than 22% of those models.
What does the Arecovas AR-DF002 cost to run per year?
At roughly $51 a year to run, ranking #110 of 519, the Arecovas AR-DF002 costs less than the typical dehumidifier model we track. Size-adjusted, this model trails most of its class on efficiency, ahead of just 22% of dehumidifier models we track. Its IEF of 1.75 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Alorair Helios D35 at $51/yr runs a little cheaper and the Bosch Dry 2000 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 Arecovas AR-DF002's $51/yr adds up to roughly $408 in electricity alone, before purchase price or repairs.
By the numbers
The Arecovas AR-DF002 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 Arecovas AR-DF002 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Arecovas AR-DF002 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 Arecovas AR-DF002 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 23 pints/day, the Arecovas AR-DF002 is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its IEF of 1.75, below the class median of 2.01, reflects integrated energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 Arecovas AR-DF002 cheap to run?
Yes. Its $51/yr running cost puts it at rank #110 of 519, below what most dehumidifier models we track cost to run.
How much does the Arecovas AR-DF002 cost per month?
About $4.24 a month, which is the $51 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: 274 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $51 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Arecovas AR-DF002 for its size?
22nd percentile once size is factored in, a fairly typical result for the class.
