Model
Moiswell Director W160
Rank #501 means 500 of the 519 dehumidifier models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Moiswell Director W160 cost to run per year?
At $117 a year to run, the Moiswell Director W160 is among the most expensive to run in its class, ranking #501 of 519 dehumidifier models we track. Once capacity is factored in, it outperforms 96% of the dehumidifier models we track on efficiency, near the very top of the normalized ranking. The IEF figure of 2.25 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 Admiral WP160 at $117/yr runs a little cheaper and the Moiswell Director WP160 at $117/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 Director W160's $117/yr adds up to roughly $936 in electricity alone, before purchase price or repairs.

By the numbers
The Moiswell Director W160 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 $117/yr, here is what the Moiswell Director W160 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 Director W160 costs about $1170. That is roughly $530 more than the class median, which would run closer to $640 over the same ten years.
How the Moiswell Director W160 compares
The dehumidifier class we track runs from $19 to $521 a year. At $117/yr, it runs about $53 a year above the class median of $64, and it is about $98 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 65 pints/day, the Moiswell Director W160 is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and larger dehumidifier models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. The IEF of 2.25 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 Moiswell Director W160 cheap to run?
Not especially. At $117 a year it ranks #501 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 Moiswell Director W160 cost per month?
Roughly $9.71/mo, spreading the $117/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 628 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $117 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Moiswell Director W160 for its size?
96th 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.
