An activated carbon filter can remove gaseous pollutants, such as formaldehyde, volatile organic compounds (VOCs), nitrogen dioxide, ozone, and so on. Thus does an air purifier dry out the air in this condition? It affects slightly. When the air purifier is equipped with an activated carbon layer or carbon cloth layer, there is often a competitive relationship. That is to say activated carbon not only can absorb pollutants but also absorb water. The activated carbon filter will absorb a certain amount of water molecules but the value is not too large. Activated carbon traps these gases on its surface. Water vapor may also bind together with the activated carbon in this way, reducing indoor humidity at some level, but the effect is too small to achieve dry air.
