Model
Omni Max ODA22M1WGAHW
Rank #127 means 126 of the 519 dehumidifier models we track cost less to run each year; the 10th efficiency percentile means it uses less energy for its size than 10% of those models.
What does the Omni Max ODA22M1WGAHW cost to run per year?
Among the 519 dehumidifier models we track, the Omni Max ODA22M1WGAHW sits in the below-average-cost group, rank #127, at roughly $51 a year. Its size-adjusted efficiency percentile of 10 means the low running cost, where it exists, is driven almost entirely by capacity rather than efficiency. At a IEF of 1.7, 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 Pelonis PAD22C1DWTS at $51/yr runs a little cheaper and the Glowells PD82A at $51/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 Omni Max ODA22M1WGAHW's $51/yr adds up to roughly $408 in electricity alone, before purchase price or repairs.

By the numbers
The Omni Max ODA22M1WGAHW 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 $51/yr, here is what the Omni Max ODA22M1WGAHW adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Omni Max ODA22M1WGAHW costs about $510. That is roughly $130 less than the class median, which would run closer to $640 over the same ten years.
How the Omni Max ODA22M1WGAHW compares
The dehumidifier class we track runs from $19 to $521 a year. At $51/yr, it runs about $13 a year cheaper than the class median of $64, and it is about $32 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.27 pints/day, the Omni Max ODA22M1WGAHW 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 1.7 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). 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 Omni Max ODA22M1WGAHW cheap to run?
Yes. Its $51/yr running cost puts it at rank #127 of 519, below what most dehumidifier models we track cost to run.
How much does the Omni Max ODA22M1WGAHW cost per month?
About $4.27 a month, which is the $51 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: 276 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $51 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Omni Max ODA22M1WGAHW for its size?
10th percentile once size is factored in, a fairly typical result for the class.
