What Capacity Dehumidifier Do I Need?

Deciding on a dehumidifier can certainly be a difficult task. 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?

A dehumidifier's pint capacity is the amount of moisture (in pints) that it is capable of removing from an area in a 24-hour period. 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. Now, to determine which one is right for you…
