Model
Fridgemaster FMDH35KX
Rank #272 means 271 of the 519 dehumidifier models we track cost less to run each year; the 81st efficiency percentile means it uses less energy for its size than 81% of those models.
What does the Fridgemaster FMDH35KX cost to run per year?
Do the math and the Fridgemaster FMDH35KX's $67/yr puts it at rank #272 of 519, right around the class average. Adjusted for its ief, it is more efficient than 81% of dehumidifier models we track, a strong result once size is taken into account. Its IEF of 2.01 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Noma Iq 043-8847-6 at $67/yr runs a little cheaper and the Hisense ADH35K26 at $67/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 Fridgemaster FMDH35KX's $67/yr adds up to roughly $536 in electricity alone, before purchase price or repairs.

By the numbers
The Fridgemaster FMDH35KX 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 $67/yr, here is what the Fridgemaster FMDH35KX adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Fridgemaster FMDH35KX costs about $670. That is roughly $30 more than the class median, which would run closer to $640 over the same ten years.
How the Fridgemaster FMDH35KX compares
The dehumidifier class we track runs from $19 to $521 a year. At $67/yr, it runs about $3 a year above the class median of $64, and it is about $48 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 35.32 pints/day, the Fridgemaster FMDH35KX 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. Its IEF of 2.01, above 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 Fridgemaster FMDH35KX cheap to run?
It is about average. At $67 a year it ranks #272 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Fridgemaster FMDH35KX cost per month?
Roughly $5.61/mo, spreading the $67/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 363 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $67 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Fridgemaster FMDH35KX for its size?
81st percentile once size is factored in, a fairly typical result for the class.
