How does a dehumidifier work?

The cooling part of the machine will suck in humid air and condense it into water, then the remaining air will escape. The dehumidifier operates continuously like this to help create air with the most suitable humidity level to prevent mold from growing, reduce the risk of illness for children, prevent wet floors, and damage electronics, machinery, etc.
How does air conditioning dehumidify?

When the air conditioner operates in Dry mode, the fan and internal components of the unit still run. However, the evaporator will not blow out cold air like in Cool mode. The air with water vapor in the room passing through the unit will condense.

Should I buy a dehumidifier?
Although the air conditioner has a good dehumidifying mode (Dry), it is only a temporary dehumidification mode. When used for a long time, it will have disadvantages related to cost, health and the life of the air conditioner.
The dehumidifier is specially designed for dehumidification, so the amount of water absorbed is higher. In addition, the dehumidifier also works more efficiently and has a larger capacity, allowing the humidity threshold to be set very low, up to about 30%, avoiding wasting electricity.
The dehumidifier will handle excess moisture perfectly, you will no longer have to worry about high humidity in the air - the main cause of mold and bacteria growth, affecting health.
Therefore, if you only want to dehumidify the air, especially during the humid season (February & March every year), you should choose a dehumidifier.
