Model
Dumos AS-CSJ72XK-5WT-OL
Rank #83 means 82 of the 519 dehumidifier models we track cost less to run each year; the 84th efficiency percentile means it uses less energy for its size than 84% of those models.
What does the Dumos AS-CSJ72XK-5WT-OL cost to run per year?
The Dumos AS-CSJ72XK-5WT-OL runs for about $48 a year, landing it near the bottom of the cost table at rank #83 of 519 dehumidifier models we track. Its size-adjusted efficiency percentile of 84 sits well above the class median, a clearly above-average efficiency result. The IEF figure of 2.04 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Concetta AS-CSJ72XK-5WT-OL at $48/yr runs a little cheaper and the Edx AS-CSJ72XK-5WT-OL at $48/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 Dumos AS-CSJ72XK-5WT-OL's $48/yr adds up to roughly $384 in electricity alone, before purchase price or repairs.

By the numbers
The Dumos AS-CSJ72XK-5WT-OL 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 $48/yr, here is what the Dumos AS-CSJ72XK-5WT-OL adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Dumos AS-CSJ72XK-5WT-OL costs about $480. That is roughly $160 less than the class median, which would run closer to $640 over the same ten years.
How the Dumos AS-CSJ72XK-5WT-OL compares
The dehumidifier class we track runs from $19 to $521 a year. At $48/yr, it runs about $16 a year cheaper than the class median of $64, and it is about $29 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 25 pints/day, the Dumos AS-CSJ72XK-5WT-OL 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 2.04, 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 Dumos AS-CSJ72XK-5WT-OL cheap to run?
Yes. Its $48/yr running cost puts it at rank #83 of 519, below what most dehumidifier models we track cost to run.
How much does the Dumos AS-CSJ72XK-5WT-OL cost per month?
About $3.97 a month, which is the $48 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: 257 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $48 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Dumos AS-CSJ72XK-5WT-OL for its size?
84th 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.
