About the pint numbers: capacity ratings on this page mix two standards. hOmeLabs lists DOE test pints, measured at cooler standard conditions, while AEOCKY, DECIUU and Trazico headline max condition pints measured at 95°F and 90 percent humidity. A max rating runs roughly two to two and a half times the DOE figure for the same machine, so the table marks each number to let you compare like with like.
Our method
How we score
Every dehumidifier runs through the same scorecard, so the numbers mean the same thing across brands. I weight what owners feel day to day, then roll it into one score out of 100. Capacity and coverage carry the most weight, because a unit too small for the space never wins however nice it looks. I set scores before checking prices. Capacity figures follow each manufacturer listing, and where a maker publishes only a peak number we show it as "up to", so weigh capacity alongside coverage rather than on its own.
Buying guide
How to choose the right one
Efficiency matters most when it runs a lot
The longer a dehumidifier runs, the more its efficiency shows up on the bill. For a basement or damp home that runs all season, an Energy Star unit pays back the small premium.
Right size still comes first
An efficient unit that is too small runs constantly and wastes the advantage. Size to the space first, then pick the efficient model in that capacity.

I run My Best Dehumidifier and score every unit on one consistent scorecard: capacity, coverage, drainage, owner rating and value. I do not sell dehumidifiers and no brand owns any part of this site. Scores are set before prices are checked, so a good deal never buys a better ranking. More about how this site works.
