With increasingly serious air pollution, air purifier has become a very familiar household appliance. However, there are still many questions about this kind of product among consumers, such as does an air purifier dry out the air? Actually, air purifiers won't dry out the air. The function of an air purifier is not to remove moisture from the air like a dehumidifier. It can absorb, decompose and transform various air pollutants, remove dust, pollen, dander and other substances that make the air dry, improve air quality, and provide users with clean and safe air. The air purifier will not affect the indoor humidity, it just purifies the air, as the role of window ventilation. The activated carbon filter in the air purifier will have a slight impact on humidity. The impact is very small, which can be ignored.
An air purifier won't dry out the air
Air purifier refers to a product that can absorb, decompose or transform pretty air pollutants (generally including PM2.5, dust, pollen, peculiar smell, decoration pollution such as formaldehyde, bacteria, allergens, etc.) and effectively improve air cleanliness. The air purifier has several layers of filter, mainly composed of a motor, fan, and air filter. Its working principle is that the motor and fan make indoor air circulate. Through the air filter, the polluted air is adsorbed and removed. Only clean air could come from the filter. The filter element can effectively filter the dust, particles, and peculiar smell in the air, and the purified fresh air is blown into the room through the fan. So the answer to does air purifier dry out the air is no. Air purifiers do not reduce indoor humidity, they can only improve indoor air quality. In the process of air purifier purifying the air and improving air quality, the humidity will not be affected.
Does an air purifier dry out the air? ---Different Type of air purifier varies a little
Generally speaking, air purifiers do not have the effect of dehumidifying and drying air, unless the relevant function is specified. If the filtration work principle like air conditioning, that is, there is a filter layer and then cooling. The water in the air will be liquefied because of the cold, thus reducing the water in the air; In addition, if the air purifier joins the activated carbon filter, it will also affect the degree of indoor dryness to a certain extent. 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.
