A portable dehumidifier designed for attics with many of the same qualities as one designed for a crawl space can be beneficial. You can install an attic dehumidifier into the HVAC system much like a whole-house dehumidifier.

Placing a dehumidifier in converted attic spaces can make spending time in the attic more pleasant and prevent damage to items placed in the room, making you more likely to return.
