Model
Moiswell Defender S60
Rank #173 means 172 of the 519 dehumidifier models we track cost less to run each year; the 32nd efficiency percentile means it uses less energy for its size than 32% of those models.
What does the Moiswell Defender S60 cost to run per year?
The Moiswell Defender S60 is a relatively cheap runner for its class: about $53 a year, rank #173 of 519. Its 32th size-adjusted efficiency percentile is a step behind the class median, though not among the weakest results. The IEF figure of 1.84 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Moiswell Defender MS7R at $53/yr runs a little cheaper and the Moiswell Defender S60R at $53/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 Moiswell Defender S60's $53/yr adds up to roughly $424 in electricity alone, before purchase price or repairs.
Also sold as: Airecoler Atlas T70.
By the numbers
The Moiswell Defender S60 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 $53/yr, here is what the Moiswell Defender S60 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Moiswell Defender S60 costs about $530. That is roughly $110 less than the class median, which would run closer to $640 over the same ten years.
How the Moiswell Defender S60 compares
The dehumidifier class we track runs from $19 to $521 a year. At $53/yr, it runs about $11 a year cheaper than the class median of $64, and it is about $34 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 24.43 pints/day, the Moiswell Defender S60 is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. The IEF of 1.84 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). 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 Moiswell Defender S60 cheap to run?
Yes, relatively. At $53 a year it ranks #173 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Moiswell Defender S60 cost per month?
Roughly $4.41/mo, spreading the $53/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 285 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $53 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Moiswell Defender S60 for its size?
32nd percentile once size is factored in, a fairly typical result for the class.
