How does a dehumidifier work?
What do dehumidifiers do to reduce humidity at home? The process is fairly simple:
- The dehumidifier’s fan mechanism pulls in air from your home
- This air is cooled inside the dehumidifier, and the moisture condenses into water
- The water is separated off into a different section, and the drier air is lightly re-heated
- This air is then released back into the room with much less moisture
- The unit will switch off when the room reaches the desired humidity level, or when the water container is full
