What sits beside it in the ranking
KNKA PRO PD30MA-20 ($43/yr, 230 kWh/yr) costs a little more to run than the KNKA PD30MA-20. Glowells PD12A ($42/yr, 225 kWh/yr) costs a little less.
Within the KNKA lineup
The KNKA PD30MA-20 is the only dehumidifier from KNKA that ENERGY STAR currently certifies, so there's no same-brand model to weigh it against here, only the full dehumidifier category.
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.
Weighing a replacement
The KNKA PD30MA-20 is already efficient for its category at $43/year. If you're shopping and comparing options, this is roughly what a well-chosen new dehumidifier costs to run.

Protecting what you have
Whether or not the KNKA PD30MA-20 ever needs replacing, a repair is the more common failure for a dehumidifier, one a protection plan budgets for ahead of time.
