Model
Sumell AS-CSJ72XK-4D5WT-OL
Rank #42 means 41 of the 519 dehumidifier models we track cost less to run each year; the 42nd efficiency percentile means it uses less energy for its size than 42% of those models.
What does the Sumell AS-CSJ72XK-4D5WT-OL cost to run per year?
Rank #42 of 519 puts the Sumell AS-CSJ72XK-4D5WT-OL among the cheapest dehumidifier models we track to keep running, at roughly $34 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 42% of the models we track. Its IEF of 1.89 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Smug AS-CSJ72XK-4D5WT-OL at $34/yr runs a little cheaper and the Sweetcrispy AS-CSJ72XK-4D5WT-OL at $34/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-4D5WT-OL's $34/yr adds up to roughly $272 in electricity alone, before purchase price or repairs.

By the numbers
The Sumell AS-CSJ72XK-4D5WT-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 $34/yr, here is what the Sumell AS-CSJ72XK-4D5WT-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-4D5WT-OL costs about $340. That is roughly $300 less than the class median, which would run closer to $640 over the same ten years.
How the Sumell AS-CSJ72XK-4D5WT-OL compares
The dehumidifier class we track runs from $19 to $521 a year. At $34/yr, it runs about $30 a year cheaper than the class median of $64, and it is about $15 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 16 pints/day, the Sumell AS-CSJ72XK-4D5WT-OL 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. The IEF of 1.89 on this model, below 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-4D5WT-OL cheap to run?
Yes. Its $34/yr running cost puts it at rank #42 of 519, below what most dehumidifier models we track cost to run.
How much does the Sumell AS-CSJ72XK-4D5WT-OL cost per month?
About $2.8 a month, which is the $34 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: 181 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $34 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Sumell AS-CSJ72XK-4D5WT-OL for its size?
42nd percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
