A portable dehumidifier is a movable and plug-n-play air humidity remover machine. By creating a dry climate, it helps prevent mold growth, improve air quality, and reduce property damage. It works by pulling in moist air and passing it over a cold coil, where the moisture condenses into water droplets collected in a reservoir or drained away. The dry air is then released back into the room. Most mobile dehumidification systems have inbuilt humidistat. It allows users to set the desired humidity level.
