Model
Iululu 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 Iululu AS-CSJ72XK-4D5WT-OL cost to run per year?
The Iululu AS-CSJ72XK-4D5WT-OL runs for about $34 a year, landing it near the bottom of the cost table at rank #42 of 519 dehumidifier models we track. Capacity-normalized, it ranks ahead of 42% of dehumidifier models we track, right in the class's middle band. At a IEF of 1.89, 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 Gianna AS-CSJ72XK-4D5WT-OL at $34/yr runs a little cheaper and the Jioabl 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 Iululu AS-CSJ72XK-4D5WT-OL's $34/yr adds up to roughly $272 in electricity alone, before purchase price or repairs.

By the numbers
The Iululu 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 Iululu 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 Iululu 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 Iululu 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 Iululu 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, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. Beyond size, its IEF of 1.89, below 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 Iululu 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 Iululu 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 Iululu 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.
