Model
Waykar PD160B-PRO-G
Rank #35 means 34 of the 519 dehumidifier models we track cost less to run each year; the 3rd efficiency percentile means it uses less energy for its size than 3% of those models.
What does the Waykar PD160B-PRO-G cost to run per year?
Among the 519 dehumidifier models we track, the Waykar PD160B-PRO-G's $27/yr running cost ranks it #35, comfortably in the cheap-to-run group. Its size-adjusted efficiency percentile of 3 means its running cost, whatever it is, owes almost nothing to efficiency and almost everything to capacity. At a IEF of 1.91, 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 PD160B-PRO-B at $27/yr runs a little cheaper and the Wellsle PD21MA at $34/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 PD160B-PRO-G's $27/yr adds up to roughly $216 in electricity alone, before purchase price or repairs.

By the numbers
The Waykar PD160B-PRO-G 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 $27/yr, here is what the Waykar PD160B-PRO-G 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 PD160B-PRO-G costs about $270. That is roughly $370 less than the class median, which would run closer to $640 over the same ten years.
How the Waykar PD160B-PRO-G compares
The dehumidifier class we track runs from $19 to $521 a year. At $27/yr, it runs about $37 a year cheaper than the class median of $64, and it is about $8 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 10.16 pints/day, the Waykar PD160B-PRO-G is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its IEF of 1.91, below the class median of 2.01, reflects integrated energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 PD160B-PRO-G cheap to run?
Yes. Its $27/yr running cost puts it at rank #35 of 519, below what most dehumidifier models we track cost to run.
How much does the Waykar PD160B-PRO-G cost per month?
About $2.23 a month, which is the $27 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: 144 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $27 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar PD160B-PRO-G for its size?
3rd percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
