MOISWELL Defender MP70: running cost
The MOISWELL Defender MP70 is certified by ENERGY STAR at 530 kWh a year, one of the more expensive models in its category to run among dehumidifiers currently certified.
That $100 is priced at 18.8¢/kWh, the average of all 51 state rates this site tracks. Your own state's rate is one click away.
Efficient, or not, for a dehumidifier
The category average is 378 kWh/yr; this model runs 40.2% above it, ranking 520 of 546 dehumidifiers tracked here for running cost. That average is drawn from all 546 dehumidifiers ENERGY STAR currently certifies, not an outside number, a $29/year gap from this model at the national rate. Full sourcing is in the sourcing notes.
Right next to it on the list
A rank or two either side of the MOISWELL Defender MP70: MOISWELL Defender MP145 ($100/yr, 530 kWh/yr), then TCL T50DC9R ($100/yr, 530 kWh/yr).
Comparing MOISWELL's own models
Ranked 18 of MOISWELL's 24 certified dehumidifiers, this sits between the Defender M7R ($54/yr, the brand's cheapest) and the Marshal WP160 ($118/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?
The MOISWELL Defender MP70 runs above its category average. If the dehumidifier you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $100/year every year.
Compare current ENERGY STAR certified dehumidifiers before buying.
If you're keeping it
A dehumidifier like the MOISWELL Defender MP70 is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
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.
