Model
Waykar; Kesnos; Yaufey; Fehom YDW-120
Rank #307 means 306 of the 519 dehumidifier models we track cost less to run each year; the 44th efficiency percentile means it uses less energy for its size than 44% of those models.
What does the Waykar; Kesnos; Yaufey; Fehom YDW-120 cost to run per year?
Do the math and the Waykar; Kesnos; Yaufey; Fehom YDW-120's $71/yr puts it at rank #307 of 519, right around the class average. Normalized for capacity, it beats 44% of dehumidifier models we track, an average result for the class. Its IEF of 2.02 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Waykar; Kesnos; Yaufey; Fehom YDG-120 at $71/yr runs a little cheaper and the Waykar; Kesnos; Yaufey; Fehom YDY-120 at $71/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 Waykar; Kesnos; Yaufey; Fehom YDW-120's $71/yr adds up to roughly $568 in electricity alone, before purchase price or repairs.
Also sold as: Waykar; Kesnos; Yaufey; Fehom YDA-120.
By the numbers
The Waykar; Kesnos; Yaufey; Fehom YDW-120 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 $71/yr, here is what the Waykar; Kesnos; Yaufey; Fehom YDW-120 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Waykar; Kesnos; Yaufey; Fehom YDW-120 costs about $710. That is roughly $70 more than the class median, which would run closer to $640 over the same ten years.
How the Waykar; Kesnos; Yaufey; Fehom YDW-120 compares
The dehumidifier class we track runs from $19 to $521 a year. At $71/yr, it runs about $7 a year above the class median of $64, and it is about $52 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 35 pints/day, the Waykar; Kesnos; Yaufey; Fehom YDW-120 is a mid-size dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. The IEF of 2.02 on this model, above 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 Waykar; Kesnos; Yaufey; Fehom YDW-120 cheap to run?
It is about average. At $71 a year it ranks #307 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Waykar; Kesnos; Yaufey; Fehom YDW-120 cost per month?
Roughly $5.91/mo, spreading the $71/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 382 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $71 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Waykar; Kesnos; Yaufey; Fehom YDW-120 for its size?
44th percentile once size is factored in, a fairly typical result for the class.
