Model
Waykar CTH150PD
Rank #335 means 334 of the 519 dehumidifier models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Waykar CTH150PD cost to run per year?
The Waykar CTH150PD costs about $87 a year to run, more than most of the 519 dehumidifier models we track; it ranks #335. Size-adjusted, this model beats 96% of dehumidifier models we track on efficiency, a standout even among the class's efficient models. The IEF figure of 2.2 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 CTH150D at $87/yr runs a little cheaper and the Megalight PD-HPC750-WT at $88/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 CTH150PD's $87/yr adds up to roughly $696 in electricity alone, before purchase price or repairs.

By the numbers
The Waykar CTH150PD 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 $87/yr, here is what the Waykar CTH150PD 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 CTH150PD costs about $870. That is roughly $230 more than the class median, which would run closer to $640 over the same ten years.
How the Waykar CTH150PD compares
The dehumidifier class we track runs from $19 to $521 a year. At $87/yr, it runs about $23 a year above the class median of $64, and it is about $68 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.43 pints/day, the Waykar CTH150PD 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. Beyond size, its IEF of 2.2, above the class median of 2.01, is the class's own efficiency yardstick, integrated energy factor, and it is what separates two similarly sized models with different running costs.
- 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 CTH150PD cheap to run?
Its $87/yr running cost, rank #335 of 519, is above what most dehumidifier models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Waykar CTH150PD cost per month?
About $7.28 a month, which is the $87 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: 471 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $87 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar CTH150PD for its size?
96th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
