Dehumidifiers can be sized based on the physical aspect—you can say a dehumidifier is big or small by just looking at it and determining the size discrepancy. However, did you know that these units are sized according to the amount of moisture they can extract from the air? That’s right; a dehumidifier is sized according to the amount of water removed per cycle. This water is measured in pints. The smallest dehumidifier removes just a few oz of moisture while the largest can eliminate 100+ pints of water. The normal classification however ranges from 30-pint to 100+ pint dehumidifiers.
