Model
Aux ADT50V1
Rank #358 means 357 of the 519 dehumidifier models we track cost less to run each year; the 90th efficiency percentile means it uses less energy for its size than 90% of those models.
What does the Aux ADT50V1 cost to run per year?
The Aux ADT50V1 is a relatively costly runner for its class: about $94 a year, rank #358 of 519. Once capacity is factored in, it outperforms 90% of the dehumidifier models we track on efficiency, not just on headline running cost. At a IEF of 2.01, 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 Honeywell Home DHM065R4000/U at $93/yr runs a little cheaper and the Garvee G-AD50PT at $94/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 Aux ADT50V1's $94/yr adds up to roughly $752 in electricity alone, before purchase price or repairs.
Also sold as: Garvee G-AD50PT, Quilo QLDAD50WK, Quilo QLDAD50PWK, Waykar CHWA150A, Waykar CHWA150PA.
By the numbers
The Aux ADT50V1 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 $94/yr, here is what the Aux ADT50V1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Aux ADT50V1 costs about $940. That is roughly $300 more than the class median, which would run closer to $640 over the same ten years.
How the Aux ADT50V1 compares
The dehumidifier class we track runs from $19 to $521 a year. At $94/yr, it runs about $30 a year above the class median of $64, and it is about $75 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.67 pints/day, the Aux ADT50V1 is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, among dehumidifier models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. The IEF of 2.01 on this model, above 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 Aux ADT50V1 cheap to run?
Not especially. At $94 a year it ranks #358 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Aux ADT50V1 cost per month?
Roughly $7.8/mo, spreading the $94/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 504 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $94 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Aux ADT50V1 for its size?
90th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
