Model
Waykar CTH80D
Rank #163 means 162 of the 519 dehumidifier models we track cost less to run each year; the 39th efficiency percentile means it uses less energy for its size than 39% of those models.
What does the Waykar CTH80D cost to run per year?
Among the 519 dehumidifier models we track, the Waykar CTH80D sits in the below-average-cost group, rank #163, at roughly $53 a year. Its size-adjusted efficiency percentile of 39 suggests its capacity is doing more work than its efficiency to keep the headline cost down. The IEF figure of 1.85 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Vissani VAD25S1BWTS at $53/yr runs a little cheaper and the Deciuu LIBRA-RCS25(Y)-N4-3(B)-25 at $53/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 CTH80D's $53/yr adds up to roughly $424 in electricity alone, before purchase price or repairs.
Also sold as: Megalight PD-MPC720-WT.
By the numbers
The Waykar CTH80D 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 $53/yr, here is what the Waykar CTH80D 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 CTH80D costs about $530. That is roughly $110 less than the class median, which would run closer to $640 over the same ten years.
How the Waykar CTH80D compares
The dehumidifier class we track runs from $19 to $521 a year. At $53/yr, it runs about $11 a year cheaper than the class median of $64, and it is about $34 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 24.84 pints/day, the Waykar CTH80D 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 1.85 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). 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 CTH80D cheap to run?
Yes. Its $53/yr running cost puts it at rank #163 of 519, below what most dehumidifier models we track cost to run.
How much does the Waykar CTH80D cost per month?
About $4.38 a month, which is the $53 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: 283 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $53 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar CTH80D for its size?
39th percentile once size is factored in, a fairly typical result for the class.
