Model
Waykar CTH120B
Rank #256 means 255 of the 519 dehumidifier models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the Waykar CTH120B cost to run per year?
At $64 a year to run, the Waykar CTH120B sits close to the middle of its class on cost, ranking #256 of 519 dehumidifier models we track. Once capacity is factored in, its efficiency percentile of 51 is fairly typical for the class, neither a standout nor a laggard. 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 Waykar CTH120A at $64/yr runs a little cheaper and the Waykar CTH120D at $64/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 CTH120B's $64/yr adds up to roughly $512 in electricity alone, before purchase price or repairs.
Also sold as: Homelabs HME0089.
By the numbers
The Waykar CTH120B 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 $64/yr, here is what the Waykar CTH120B 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 CTH120B costs about $640. That is roughly $0 less than the class median, which would run closer to $640 over the same ten years.
How the Waykar CTH120B compares
The dehumidifier class we track runs from $19 to $521 a year. At $64/yr, it sits right on the class median of $64, and it is about $45 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 32.46 pints/day, the Waykar CTH120B 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 2.01 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 CTH120B cheap to run?
It is about average. At $64 a year it ranks #256 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Waykar CTH120B cost per month?
Roughly $5.31/mo, spreading the $64/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 343 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $64 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Waykar CTH120B for its size?
51st percentile once size is factored in, a fairly typical result for the class.
