Model
Waykar CTH150PB
Rank #399 means 398 of the 519 dehumidifier models we track cost less to run each year; the 76th efficiency percentile means it uses less energy for its size than 76% of those models.
What does the Waykar CTH150PB cost to run per year?
At about $96 a year, the Waykar CTH150PB costs more to run than most dehumidifier models we track, rank #399 of 519. Capacity-normalized, it ranks ahead of 76% of dehumidifier models we track, a reasonably strong result for the class. At a IEF of 2.01, 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 CTH150PA at $96/yr runs a little cheaper and the Midea MDUDP-50AEN8-BB0B at $96/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 CTH150PB's $96/yr adds up to roughly $768 in electricity alone, before purchase price or repairs.

By the numbers
The Waykar CTH150PB 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 $96/yr, here is what the Waykar CTH150PB 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 CTH150PB costs about $960. That is roughly $320 more than the class median, which would run closer to $640 over the same ten years.
How the Waykar CTH150PB compares
The dehumidifier class we track runs from $19 to $521 a year. At $96/yr, it runs about $32 a year above the class median of $64, and it is about $77 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.66 pints/day, the Waykar CTH150PB is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and larger dehumidifier models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Beyond size, its IEF of 2.01, 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 CTH150PB cheap to run?
Its $96/yr running cost, rank #399 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 CTH150PB cost per month?
About $7.98 a month, which is the $96 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: 516 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $96 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar CTH150PB for its size?
76th 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.
