Model
Waykar; Kesnos; Yaufey; Fehom YDZ-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 YDZ-120 cost to run per year?
Among the 519 dehumidifier models we track, the Waykar; Kesnos; Yaufey; Fehom YDZ-120's $71/yr running cost ranks it #307, close to dead center. Capacity-normalized, it ranks ahead of 44% of dehumidifier models we track, right in the class's middle band. 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 YDY-120 at $71/yr runs a little cheaper and the Insignia NS-DH35WH7 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 YDZ-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 YDZ-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 YDZ-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 YDZ-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 YDZ-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 YDZ-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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. 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). IEF measures liters of water removed per kilowatt-hour; a higher IEF means less energy per pint of moisture removed for a given capacity.
- Water removal capacity (pints/day). A dehumidifier rated to remove more pints per day is built for a larger space or a more humid room, and generally draws more power to do it.
- Humidistat accuracy. A unit with a more precise humidistat cycles the compressor off once the target humidity is reached, rather than running continuously.
Common questions
Is the Waykar; Kesnos; Yaufey; Fehom YDZ-120 cheap to run?
Roughly, yes. Its $71/yr figure is close to the class median, ranking #307 of 519, neither a bargain nor a splurge on running cost.
How much does the Waykar; Kesnos; Yaufey; Fehom YDZ-120 cost per month?
About $5.91 a month, which is the $71 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 382 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $71 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar; Kesnos; Yaufey; Fehom YDZ-120 for its size?
44th percentile once size is factored in, a fairly typical result for the class.
