Model
Ludatido PD10C2-25
Rank #99 means 98 of the 519 dehumidifier models we track cost less to run each year; the 0th efficiency percentile means it uses less energy for its size than 0% of those models.
What does the Ludatido PD10C2-25 cost to run per year?
Rank #99 of 519 puts the Ludatido PD10C2-25 among the cheapest dehumidifier models we track to keep running, at roughly $49 a year. Size-adjusted, this model ranks at the very bottom of its class on efficiency, ahead of just 0% of dehumidifier models we track. Its IEF of 1.91 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Waykar CHWA80E at $48/yr runs a little cheaper and the Andte PD80K at $49/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 Ludatido PD10C2-25's $49/yr adds up to roughly $392 in electricity alone, before purchase price or repairs.
By the numbers
The Ludatido PD10C2-25 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 $49/yr, here is what the Ludatido PD10C2-25 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Ludatido PD10C2-25 costs about $490. That is roughly $150 less than the class median, which would run closer to $640 over the same ten years.
How the Ludatido PD10C2-25 compares
The dehumidifier class we track runs from $19 to $521 a year. At $49/yr, it runs about $15 a year cheaper than the class median of $64, and it is about $30 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 1.91 pints/day, the Ludatido PD10C2-25 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. Beyond size, its IEF of 1.91, below 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 Ludatido PD10C2-25 cheap to run?
Yes. Its $49/yr running cost puts it at rank #99 of 519, below what most dehumidifier models we track cost to run.
How much does the Ludatido PD10C2-25 cost per month?
About $4.08 a month, which is the $49 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: 264 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $49 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Ludatido PD10C2-25 for its size?
0th 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.
