Model
Dreo Home DR-HDH003S
Rank #107 means 106 of the 519 dehumidifier models we track cost less to run each year; the 15th efficiency percentile means it uses less energy for its size than 15% of those models.
What does the Dreo Home DR-HDH003S cost to run per year?
The Dreo Home DR-HDH003S is a relatively cheap runner for its class: about $50 a year, rank #107 of 519. Its 15th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. The IEF figure of 1.75 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Dreo DR-HDH003S at $50/yr runs a little cheaper and the Alorair Helios D35 at $51/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 Dreo Home DR-HDH003S's $50/yr adds up to roughly $400 in electricity alone, before purchase price or repairs.

By the numbers
The Dreo Home DR-HDH003S 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 $50/yr, here is what the Dreo Home DR-HDH003S adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Dreo Home DR-HDH003S costs about $500. That is roughly $140 less than the class median, which would run closer to $640 over the same ten years.
How the Dreo Home DR-HDH003S compares
The dehumidifier class we track runs from $19 to $521 a year. At $50/yr, it runs about $14 a year cheaper than the class median of $64, and it is about $31 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.09 pints/day, the Dreo Home DR-HDH003S 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 1.75 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). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Dreo Home DR-HDH003S cheap to run?
Yes, relatively. At $50 a year it ranks #107 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Dreo Home DR-HDH003S cost per month?
Roughly $4.19/mo, spreading the $50/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 271 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $50 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Dreo Home DR-HDH003S for its size?
15th percentile once size is factored in, a fairly typical result for the class.
