A rank or two either side of the MOISWELL Defender H150: MOISWELL Aegis HP150 ($100/yr, 530 kWh/yr), then MOISWELL Defender HP150 ($100/yr, 530 kWh/yr).
Same brand, different models

Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Shopping for a new one
At $100/year, this is on the expensive side for a dehumidifier; the cheapest certified model in this category runs about $20/year, worth knowing before buying either the MOISWELL Defender H150 or its replacement.
Worth comparing a few current certified models before deciding.
If you're keeping it
$100/year to run is the predictable cost of the MOISWELL Defender H150; a protection plan covers the unpredictable one, a repair bill.
Where this number comes from
Nothing here is estimated from a nameplate wattage; the 530 kWh/yr is ENERGY STAR's own certified figure for this model. The full Dehumidifier category page shows all 546 dehumidifiers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
