Model
Airecoler Sailing P155
Rank #482 means 481 of the 519 dehumidifier models we track cost less to run each year; the 47th efficiency percentile means it uses less energy for its size than 47% of those models.
What does the Airecoler Sailing P155 cost to run per year?
Do the math and the Airecoler Sailing P155's $98/yr puts it at rank #482 of 519, one of the costlier dehumidifier models we track to keep running. Adjusted for size, it is more efficient than 47% of dehumidifier models we track, a middling result. The IEF figure of 2.01 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Airzentti ACD155P-PG100(B) at $98/yr runs a little cheaper and the Airecoler Sailing P155A at $98/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 Airecoler Sailing P155's $98/yr adds up to roughly $784 in electricity alone, before purchase price or repairs.

By the numbers
The Airecoler Sailing P155 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 $98/yr, here is what the Airecoler Sailing P155 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Airecoler Sailing P155 costs about $980. That is roughly $340 more than the class median, which would run closer to $640 over the same ten years.
How the Airecoler Sailing P155 compares
The dehumidifier class we track runs from $19 to $521 a year. At $98/yr, it runs about $34 a year above the class median of $64, and it is about $79 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 50 pints/day, the Airecoler Sailing P155 is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, among dehumidifier models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. Beyond size, its IEF of 2.01, above 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). 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 Airecoler Sailing P155 cheap to run?
Not especially. At $98 a year it ranks #482 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Airecoler Sailing P155 cost per month?
Roughly $8.2/mo, spreading the $98/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 530 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $98 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Airecoler Sailing P155 for its size?
47th 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.
