What Are The Different Types of Dehumidifier? There are 3 main types of dehumidifer, Passive (not powered by electricity), Compressor and Desiccant.
Passive dehumidifiers are essentially crystals that absorb moisture. These can be excellent at helping to reduce moisture in small areas such as cupboards and lockers, and small boat cabins, but they aren’t really suitable for larger boat cabins and areas.
Electric dehumidifiers fall in to two categories: compressor and desiccant.
Both types work very well, but compressor types can struggle in the lower temperatures often associated with winter. Desiccant use slightly more power, but work very well in lower temperatures. They normally heat the air slightly too, helping to prevent condensation further.
