How to Choose the Right Dehumidifier?

You have to determine the right size dehumidifier based on a comparison of room size and moisture level.

Types of Dehumidifiers

Dehumidifiers come in two basic types, desiccant, and refrigerant. For lower humidity levels, desiccant models are the perfect pick. These units will remove moisture from the air by using chemicals instead of condensation. Desiccant dehumidifiers have more limited capacity and less economical than others. It's best to use in spaces where the temperature is less than 18 degrees centigrade.

If your room's temperature is consistently hot and humid, refrigerant dehumidifiers are the best choice. These have high capacity ratings and operate efficiently at high temperatures than desiccant models. This will use a heat exchange coil to extract moisture from the air. A refrigerant dehumidifier is most suitable for basements, crawl spaces, and attics.
