Model
Iululu AS-CSJ72XK-2WT-OL
Rank #3 means 2 of the 519 dehumidifier models we track cost less to run each year; the 35th efficiency percentile means it uses less energy for its size than 35% of those models.
What does the Iululu AS-CSJ72XK-2WT-OL cost to run per year?
Few dehumidifier models we track undercut the Iululu AS-CSJ72XK-2WT-OL on cost; at about $19 a year it holds rank #3 of 519. Normalized for capacity, it beats only 35% of dehumidifier models we track, a below-average efficiency result. At a IEF of 1.93, 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-2WT-OL at $19/yr runs a little cheaper and the Jioabl AS-CSJ72XK-2WT-OL at $19/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-2WT-OL's $19/yr adds up to roughly $152 in electricity alone, before purchase price or repairs. At rank #3 of 519, it is one of the single cheapest dehumidifier models we track to run, in the top one percent on cost.
Also sold as: Concetta AS-CSJ72XK-2WT-OL.
By the numbers
The Iululu AS-CSJ72XK-2WT-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 $19/yr, here is what the Iululu AS-CSJ72XK-2WT-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-2WT-OL costs about $190. That is roughly $450 less than the class median, which would run closer to $640 over the same ten years.
How the Iululu AS-CSJ72XK-2WT-OL compares
The dehumidifier class we track runs from $19 to $521 a year. At $19/yr, it runs about $45 a year cheaper than the class median of $64, and it is the cheapest dehumidifier to run in the class among the models we track.
What drives its running cost
At 9 pints/day, the Iululu AS-CSJ72XK-2WT-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. The IEF of 1.93 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). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Iululu AS-CSJ72XK-2WT-OL cheap to run?
Yes, relatively. At $19 a year it ranks #3 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Iululu AS-CSJ72XK-2WT-OL cost per month?
Roughly $1.62/mo, spreading the $19/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 105 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $19 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Iululu AS-CSJ72XK-2WT-OL for its size?
35th 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.
