The numbers to know
Pints per day
Capacity is water removed under a specified test condition. Compare portable DOE 2019 figures at 65°F / 60% RH; whole-home units use 73°F / 60% RH.
Integrated energy factor
IEF is liters of water removed per kilowatt-hour. A larger IEF means more removal per unit of electricity under the rating method.
How we score dehumidifiers
Capacity for dated price 30%; efficiency 25%; drainage 20%; minimum temperature 10%; published noise 10%; warranty 5%. At least 90% documented weighted evidence is required. Portable and whole-home groups stay separate.
