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
Match capacity to the floor
A single room is the easiest case to size. Up to about 1,500 sq ft, a small to mid unit is plenty. For a large open living room, step up to 25 to 40 pints so it holds the space without running flat out.
Placement matters more than you think
Give the unit room to breathe. Set it a little away from walls and furniture so air moves in and back out freely, and put it near the dampest part of the room if there is one. Boxed into a corner, even a well sized unit struggles.

The temperature the DOE has tested capacity at since 2019, down from 80°F. That change is why a unit sold as 50 pints today matches what older listings called 70 pints.

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.
