Model
Waykar; Kesnos; Yaufey; Fehom YDG-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 YDG-120 cost to run per year?
Ranking #307 of 519, the Waykar; Kesnos; Yaufey; Fehom YDG-120 runs at roughly $71 a year, neither the cheapest nor the priciest in its class. Normalized for capacity, it beats 44% of dehumidifier models we track, an average result for the class. At a IEF of 2.02, 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 Waykar; Kesnos; Yaufey; Fehom YDA-120 at $71/yr runs a little cheaper and the Waykar; Kesnos; Yaufey; Fehom YDW-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 YDG-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 YDG-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 YDG-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 YDG-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 YDG-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 YDG-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, putting it squarely in the middle of the class on the size lever that drives most of the cost. Its IEF of 2.02, above the class median of 2.01, reflects integrated energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 YDG-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 YDG-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 YDG-120 for its size?
44th percentile once size is factored in, a fairly typical result for the class.
