Right next to it on the list
A rank or two either side of the SMUG AS-CSJ72XK-4D5WT-OL: Patiosunny PS1415DH50WT ($34/yr, 181 kWh/yr), then SUMELL AS-CSJ72XK-4D5WT-OL ($34/yr, 181 kWh/yr).
Same brand, different models
Ranked 2 of SMUG's 3 certified dehumidifiers, this sits between the AS-CSJ72XK-2WT-OL ($20/yr, the brand's cheapest) and the AS-CSJ72XK-5WT-OL ($48/yr, its priciest).
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.
Is it worth replacing?
Efficient as certified dehumidifiers go, $34/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
At $34/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
Where this number comes from
Nothing here is estimated from a nameplate wattage; the 181 kWh/yr is ENERGY STAR's own certified figure for this model. At rank 55 of 546 for running cost, see the dehumidifier category page for the rest of the field, or the guide to how much your state matters.
