Arecovas AR-DF006: running cost
At 285 kWh/yr, the Arecovas AR-DF006's ENERGY STAR certification puts it cheaper than most models in its category to run against every other certified dehumidifier.

Efficient, or not, for a dehumidifier
Against the category average of 378 kWh/yr, this model uses 24.6% less, ranking 201 of 546 dehumidifiers tracked here for running cost. That average is drawn from all 546 dehumidifiers ENERGY STAR currently certifies, not an outside number, a $17/year gap from this model at the national rate. Full sourcing is in the sourcing notes.
Right next to it on the list
A rank or two either side of the Arecovas AR-DF006: Airzentti ACDOSOP-PG200 ($54/yr, 285 kWh/yr), then Easykey AQUA-RCS25 (Y)-N4-3-25 ($54/yr, 285 kWh/yr).
Same brand, different models
Ranked 3 of Arecovas's 4 certified dehumidifiers, this sits between the AR-DF001 ($36/yr, the brand's cheapest) and the AR-DF005 ($64/yr, its priciest).
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Is it worth replacing?
Efficient as certified dehumidifiers go, $54/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
The Arecovas AR-DF006 already costs $54/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
Where this number comes from
