Model
Aprilaire E130
Rank #513 means 512 of the 519 dehumidifier models we track cost less to run each year; the 99th efficiency percentile means it uses less energy for its size than 99% of those models.
What does the Aprilaire E130 cost to run per year?
Out of the 519 dehumidifier models we track, the Aprilaire E130 lands at rank #513 on cost, roughly $172 a year, one of the most expensive figures in the class. Few dehumidifier models we track are more efficient for their size than this one; its size-adjusted efficiency percentile of 99 is near the top of the 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 Deverse D025H-25Pt3 at $164/yr runs a little cheaper and the Carrier Corporation DEHXXCDA1080* at $190/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 E130's $172/yr adds up to roughly $1376 in electricity alone, before purchase price or repairs.
By the numbers
The Aprilaire E130 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 $172/yr, here is what the Aprilaire E130 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 E130 costs about $1720. That is roughly $1080 more than the class median, which would run closer to $640 over the same ten years.
How the Aprilaire E130 compares
The dehumidifier class we track runs from $19 to $521 a year. At $172/yr, it runs about $108 a year above the class median of $64, and it is about $153 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 105 pints/day, the Aprilaire E130 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. 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 E130 cheap to run?
Its $172/yr running cost, rank #513 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 E130 cost per month?
About $14.32 a month, which is the $172 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: 926 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $172 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Aprilaire E130 for its size?
99th 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.
