For instance, if you have a 30-pint dehumidifier, it’s going to be able to remove at least 30 pints of liquid daily.

Also, the dehumidifier's capacity will loosely tell you how much square feet it covers. Thus, if you know the square footage of your room that you are planning to dehumidify, you'll have an idea of what dehumidifier to buy.

If the water returns, the mold spores will generate growing colonies of mold. Getting a dehumidifier is great for mold prevention, not for complete removal.

Remember, your dehumidifier can get infested with mold as well. Make sure to clear out your dehumidifier on a regular basis.
