Model
Dreame CVF39A
Rank #220 means 219 of the 519 dehumidifier models we track cost less to run each year; the 5th efficiency percentile means it uses less energy for its size than 5% of those models.
What does the Dreame CVF39A cost to run per year?
The Dreame CVF39A costs about $55 a year to run, a fairly typical figure for the class; it ranks #220 of 519. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 5% of the models we track. The IEF figure of 1.7 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Waykar CTH80B at $54/yr runs a little cheaper and the Upstreman UPDEH-80A at $55/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 Dreame CVF39A's $55/yr adds up to roughly $440 in electricity alone, before purchase price or repairs.
By the numbers
The Dreame CVF39A 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 $55/yr, here is what the Dreame CVF39A adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Dreame CVF39A costs about $550. That is roughly $90 less than the class median, which would run closer to $640 over the same ten years.
How the Dreame CVF39A compares
The dehumidifier class we track runs from $19 to $521 a year. At $55/yr, it runs about $9 a year cheaper than the class median of $64, and it is about $36 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 23.29 pints/day, the Dreame CVF39A 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. The IEF of 1.7 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 Dreame CVF39A cheap to run?
Roughly, yes. Its $55/yr figure is close to the class median, ranking #220 of 519, neither a bargain nor a splurge on running cost.
How much does the Dreame CVF39A cost per month?
About $4.56 a month, which is the $55 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: 295 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $55 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Dreame CVF39A for its size?
5th percentile once size is factored in, a fairly typical result for the class.
