Model
Sumell 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 Sumell AS-CSJ72XK-5WT-OL cost to run per year?
Rank #83 of 519 puts the Sumell AS-CSJ72XK-5WT-OL among the cheapest dehumidifier models we track to keep running, at roughly $48 a year. Its size-adjusted efficiency percentile of 84 sits well above the class median, a clearly above-average efficiency result. At a IEF of 2.04, 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 Smug AS-CSJ72XK-5WT-OL at $48/yr runs a little cheaper and the Sweetcrispy 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 Sumell AS-CSJ72XK-5WT-OL's $48/yr adds up to roughly $384 in electricity alone, before purchase price or repairs.

By the numbers
The Sumell 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 Sumell 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 Sumell 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 Sumell 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 Sumell 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, putting it squarely in the middle of the class on the size lever that drives most of the cost. The IEF of 2.04 on this model, above the class median of 2.01, measures integrated energy factor; it is the number to compare directly against another model's IEF if capacity is similar.
- 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 Sumell 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 Sumell 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 Sumell 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.
