Model
Humilabs OL12-D023F
Rank #16 means 15 of the 519 dehumidifier models we track cost less to run each year; the 16th efficiency percentile means it uses less energy for its size than 16% of those models.
What does the Humilabs OL12-D023F cost to run per year?
Few dehumidifier models we track undercut the Humilabs OL12-D023F on cost; at about $20 a year it holds rank #16 of 519. Adjusted for size, it is only more efficient than 16% of dehumidifier models we track, so its headline cost is mostly a function of its capacity rather than efficiency. At a IEF of 1.92, 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 Zunmos AS-CSJ72XK-2WT-OL at $19/yr runs a little cheaper and the Black+Decker BDT08TW at $22/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 Humilabs OL12-D023F's $20/yr adds up to roughly $160 in electricity alone, before purchase price or repairs.
By the numbers
The Humilabs OL12-D023F 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 $20/yr, here is what the Humilabs OL12-D023F adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Humilabs OL12-D023F costs about $200. That is roughly $440 less than the class median, which would run closer to $640 over the same ten years.
How the Humilabs OL12-D023F compares
The dehumidifier class we track runs from $19 to $521 a year. At $20/yr, it runs about $44 a year cheaper than the class median of $64, and it is about $1 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 9 pints/day, the Humilabs OL12-D023F 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. Its IEF of 1.92, 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). 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 Humilabs OL12-D023F cheap to run?
Yes, relatively. At $20 a year it ranks #16 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Humilabs OL12-D023F cost per month?
Roughly $1.7/mo, spreading the $20/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 110 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $20 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Humilabs OL12-D023F for its size?
16th 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.
