With the improvement of living standards, more and more families have purchased air purifiers and dehumidifiers. Some people may wonder whether it is necessary to turn on the dehumidifier when using the air purifier. Does their functions overlap, is it necessary to buy two machines in a house? The following mainly introduces the difference between an air purifier and a dehumidifier. If you have question when choosing electrical appliance, you'd better read this article carefully, we'll help you to figure out which one to buy.


1. Different working principle of an air purifier and dehumidifier

The air purifier adopts the principle of filtration, sucks the indoor polluted air into the purifier through the fan, and then filters and adsorbs the fine particles and odor gas in the air through the action of the filter system and the filter element, or decomposes into carbon dioxide and water.

The dehumidifier sucks the indoor air into the dehumidifier through the fan. The compressor in the fuselage can instantly condense the moisture in the air into water and flow into the water tank. As the use time increases, the moisture in the air will become less and less, so the humidity in the air is reduced. This is similar to the dehumidification function of the air conditioner, but the efficiency is not as good as a dehumidifier.

2. Different functions of an air purifier and dehumidifier

The main function of the air purifier is to purify the air. It can be used to remove odors, dust, second-hand smoke, bacterial mold, pollen, etc., What’s more, some air purifier also have functions to remove formaldehyde.

The commercial air dehumidifier is mainly used to reduce or constant the humidity of indoor air. Some dehumidifiers have a humidification function, which can regulate the air humidity within a certain range.


3. The effect of air purifier and dehumidifier is different.

Air purifier: It can effectively filter common harmful substances in the air and play a role in purifying the air, especially for families with elderly and children in the home, to reduce the occurrence of family members' respiratory diseases.


Dehumidifier: It just reduces the indoor air humidity. Although there are some air purification functions, the effect is not very obvious. The commercial portable dehumidifier has a silver ion filter at the air inlet, which mainly performs simple filtration of hair fibers and dust, and can also play a sterilizing role, but this effect is still different from the purifying effect of the air purifier.


Dehumidifiers and air purifiers, these two machines are irreplaceable, and exclusive use of special items has always been the market norm.
