Model
Seasons SD35CB1
Rank #305 means 304 of the 519 dehumidifier models we track cost less to run each year; the 53rd efficiency percentile means it uses less energy for its size than 53% of those models.
What does the Seasons SD35CB1 cost to run per year?
At $71 a year to run, the Seasons SD35CB1 sits close to the middle of its class on cost, ranking #305 of 519 dehumidifier models we track. Its 53th size-adjusted efficiency percentile is unremarkable, close to what a typical model in the class scores. 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 Midea MDUDPA-35AEN8-BB0 at $71/yr runs a little cheaper and the Coolworks TDUDPA-35AEN8-BB0 at $71/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 Seasons SD35CB1's $71/yr adds up to roughly $568 in electricity alone, before purchase price or repairs.
Also sold as: Coolworks TDUDPA-35AEN8-BB0.
By the numbers
The Seasons SD35CB1 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 $71/yr, here is what the Seasons SD35CB1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Seasons SD35CB1 costs about $710. That is roughly $70 more than the class median, which would run closer to $640 over the same ten years.
How the Seasons SD35CB1 compares
The dehumidifier class we track runs from $19 to $521 a year. At $71/yr, it runs about $7 a year above the class median of $64, and it is about $52 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 36.18 pints/day, the Seasons SD35CB1 is a mid-size dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. 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 Seasons SD35CB1 cheap to run?
It is about average. At $71 a year it ranks #305 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Seasons SD35CB1 cost per month?
Roughly $5.91/mo, spreading the $71/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 382 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $71 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Seasons SD35CB1 for its size?
53rd percentile once size is factored in, a fairly typical result for the class.
