Model
Comfort Aire BHD-35C
Rank #323 means 322 of the 519 dehumidifier models we track cost less to run each year; the 63rd efficiency percentile means it uses less energy for its size than 63% of those models.
What does the Comfort Aire BHD-35C cost to run per year?
The Comfort Aire BHD-35C costs about $71 a year to run, more than most of the 519 dehumidifier models we track; it ranks #323. Capacity-normalized, it ranks ahead of 63% of dehumidifier models we track, a reasonably strong result for the class. The IEF figure of 2.01 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Pelonis PAD35C1DWTS at $71/yr runs a little cheaper and the Omni Max ODA35M3WGAHW at $71/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-35C's $71/yr adds up to roughly $568 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BDM36WCDA.
By the numbers
The Comfort Aire BHD-35C 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 $71/yr, here is what the Comfort Aire BHD-35C 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-35C costs about $710. That is roughly $70 more than the class median, which would run closer to $640 over the same ten years.
How the Comfort Aire BHD-35C compares
The dehumidifier class we track runs from $19 to $521 a year. At $71/yr, it runs about $7 a year above the class median of $64, and it is about $52 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 36.39 pints/day, the Comfort Aire BHD-35C is a mid-size dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. Beyond size, its IEF of 2.01, 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 Comfort Aire BHD-35C cheap to run?
Its $71/yr running cost, rank #323 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 Comfort Aire BHD-35C cost per month?
About $5.92 a month, which is the $71 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: 383 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $71 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Comfort Aire BHD-35C for its size?
63rd 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.
