Model
Smug 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 Smug AS-CSJ72XK-2WT-OL cost to run per year?
At $19 a year to run, the Smug AS-CSJ72XK-2WT-OL is one of the very cheapest dehumidifier models we track, ranking #3 of 519, in the bottom five percent on cost. Its 35th size-adjusted efficiency percentile is a step behind the class median, though not among the weakest results. The IEF figure of 1.93 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Olixis AS-CSJ72XK-2WT-OL at $19/yr runs a little cheaper and the Sumell 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 Smug 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 Smug 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 Smug 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 Smug 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 Smug 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 Smug 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 Smug 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 Smug 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 Smug 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.
