What Capacity Dehumidifier Do I Need?

Not only are there many different brands and types to choose from, but dehumidifiers also tend to throw people off by use of a pint rating, in reference to models. Most know what a pint is and can visualize it but have a hard time understanding the real difference between dehumidifier models with different capacity ratings; say, a 50 pint dehumidifier versus a 70 pint dehumidifier. More importantly, the trouble lies in understanding which one is right for you and your needs.

What is a “pint” in dehumidifiers?

It is important to remember that a dehumidifier’s performance can be affected by both the size and humidity level of a given area. In general, a dehumidifier with a pint capacity rated at 70 pints or less is best for residential use, while dehumidifiers rated over 70 pints are ideal for commercial or industrial applications.
