Model
Comfort Aire BHD-22B
Rank #136 means 135 of the 519 dehumidifier models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the Comfort Aire BHD-22B cost to run per year?
At $52 a year to run, the Comfort Aire BHD-22B runs cheaper than most models in its class, ranking #136 of 519 dehumidifier models we track. Its 7th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. Its IEF of 1.7 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Seasons SD22CA1 at $52/yr runs a little cheaper and the Omni Max OD22MTWBA1RCM at $52/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 Comfort Aire BHD-22B's $52/yr adds up to roughly $416 in electricity alone, before purchase price or repairs.

By the numbers
The Comfort Aire BHD-22B 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 $52/yr, here is what the Comfort Aire BHD-22B adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Comfort Aire BHD-22B costs about $520. That is roughly $120 less than the class median, which would run closer to $640 over the same ten years.
How the Comfort Aire BHD-22B compares
The dehumidifier class we track runs from $19 to $521 a year. At $52/yr, it runs about $12 a year cheaper than the class median of $64, and it is about $33 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.31 pints/day, the Comfort Aire BHD-22B is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its IEF of 1.7, below the class median of 2.01, reflects integrated energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 Comfort Aire BHD-22B cheap to run?
Yes, relatively. At $52 a year it ranks #136 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Comfort Aire BHD-22B cost per month?
Roughly $4.3/mo, spreading the $52/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 278 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $52 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Comfort Aire BHD-22B for its size?
7th percentile once size is factored in, a fairly typical result for the class.
