Model
Doghly FDD20-5272V1R5-E
Rank #65 means 64 of the 519 dehumidifier models we track cost less to run each year; the 14th efficiency percentile means it uses less energy for its size than 14% of those models.
What does the Doghly FDD20-5272V1R5-E cost to run per year?
The Doghly FDD20-5272V1R5-E runs for about $37 a year, landing it near the bottom of the cost table at rank #65 of 519 dehumidifier models we track. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 14% of the models we track. Its IEF of 1.85 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Mionjo V3 at $36/yr runs a little cheaper and the Dollardash FDD20-5272V1R5-E at $37/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 Doghly FDD20-5272V1R5-E's $37/yr adds up to roughly $296 in electricity alone, before purchase price or repairs.

By the numbers
The Doghly FDD20-5272V1R5-E 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 $37/yr, here is what the Doghly FDD20-5272V1R5-E adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Doghly FDD20-5272V1R5-E costs about $370. That is roughly $270 less than the class median, which would run closer to $640 over the same ten years.
How the Doghly FDD20-5272V1R5-E compares
The dehumidifier class we track runs from $19 to $521 a year. At $37/yr, it runs about $27 a year cheaper than the class median of $64, and it is about $18 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 16 pints/day, the Doghly FDD20-5272V1R5-E is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and smaller dehumidifier models generally cost less to run for the same job, all else being equal. The IEF of 1.85 on this model, below 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). 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 Doghly FDD20-5272V1R5-E cheap to run?
Yes. Its $37/yr running cost puts it at rank #65 of 519, below what most dehumidifier models we track cost to run.
How much does the Doghly FDD20-5272V1R5-E cost per month?
About $3.06 a month, which is the $37 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: 198 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $37 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Doghly FDD20-5272V1R5-E for its size?
14th 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.
