Large Dehumidifiers - Dehumidifying 60 pints or more / day

Previous Dehumidifier Standards made in 2012

Changes made in 2012 required dehumidifiers to be tested at an ambient temperature of 80 degrees F and 60% humidity. The capacity is calculated at the amount of water removed per day at test conditions. As a result, most dehumidifiers were built standard as 30-, 50-, and 70-pint models, referring to the amount of moisture they remove in 24 hours under those conditions.

New 2019 Dehumidifier Standards
Dehumidifiers are now tested at 65 degrees F and 60% humidity, which is 15 degrees lower than in the past. Since there’s less water vapor to remove from cooler air, the number of pints each dehumidifier removes also dropped. The standard pint capacities under the new conditions are about 20-, 30- and 50-pint dehumidifiers (as opposed to 30-, 50-, and 70-pint models when tested at 80 degrees F)
