Model
Aprilaire E080
Rank #507 means 506 of the 519 dehumidifier models we track cost less to run each year; the 93rd efficiency percentile means it uses less energy for its size than 93% of those models.
What does the Aprilaire E080 cost to run per year?
Out of the 519 dehumidifier models we track, the Aprilaire E080 lands at rank #507 on cost, roughly $117 a year, one of the most expensive figures in the class. Size-adjusted, this model beats 93% of dehumidifier models we track on efficiency, one of the stronger results in its class. Its IEF of 2.35 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Moiswell Marshal WP160 at $117/yr runs a little cheaper and the Costway ES10429US-WH at $145/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 Aprilaire E080's $117/yr adds up to roughly $936 in electricity alone, before purchase price or repairs.
By the numbers
The Aprilaire E080 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 Aprilaire E080 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Aprilaire E080 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 Aprilaire E080 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 Aprilaire E080 is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. Beyond size, its IEF of 2.35, above the class median of 2.01, is the class's own efficiency yardstick, integrated energy factor, and it is what separates two similarly sized models with different running costs.
- Integrated Energy Factor (IEF). IEF measures liters of water removed per kilowatt-hour; a higher IEF means less energy per pint of moisture removed for a given capacity.
- Water removal capacity (pints/day). A dehumidifier rated to remove more pints per day is built for a larger space or a more humid room, and generally draws more power to do it.
- Humidistat accuracy. A unit with a more precise humidistat cycles the compressor off once the target humidity is reached, rather than running continuously.
Common questions
Is the Aprilaire E080 cheap to run?
Its $117/yr running cost, rank #507 of 519, is above what most dehumidifier models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Aprilaire E080 cost per month?
About $9.77 a month, which is the $117 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 632 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $117 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Aprilaire E080 for its size?
93rd 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.
