What is the difference between an air purifier and a dehumidifier?

With the improvement of people’s requirements for the air environment, all kinds of electrical appliances that can improve the air environment have attracted more and more attention, such as air purifiers, dehumidifiers, etc., which also have the effect of improving the air. Then air purifiers and dehumidifiers What’s the difference? Let’s take a look at the difference between a dehumidifier and an air purifier.

First, the principle is different


The air purifier adopts the principle of filtration. The indoor polluted air is sucked into the purifier through the fan, and then through the action of the filter system and the filter element, the fine particles and odor gases in the air are filtered and adsorbed, or decomposed into carbon dioxide and water. .


The dehumidifier sucks indoor air into the dehumidifier through a fan. The compressor in the body can instantly condense the moisture in the air into water and flow into the water tank. With the prolongation of use time, the moisture in the air will become less and less. , the humidity in the air is also reduced. This is similar to the dehumidification function of an air conditioner, but it is not as efficient as the dehumidification function of a dehumidifier.

Second, Different functions


The main function of the air purifier is to purify the air, which can be used to remove odor, dust, second-hand smoke, bacteria, mold, pollen, etc., and even some functions can remove formaldehyde.


Dehumidifiers are mainly used to reduce or stabilize the humidity of indoor air. Some dehumidifiers have a humidification function, which can adjust the air humidity within a certain range.

Third, the purification effect is different


Air purifiers can filter toxic and harmful substances in the air and play a role in purifying the air. The dehumidifier absorbs a part of the moisture in the indoor air to reduce the humidity, but cannot purify the air.


The dehumidifier has a silver ion filter at the air inlet, which mainly performs simple filtering of hair fibers and dust, and can also play a role in sterilization, but this effect is different from the purification effect of the air purifier.


Air purifiers belong to passive adsorption, and cannot keep up with the problem of indoor air pollution. If you want to remove formaldehyde, it is recommended to choose a scientific and effective formaldehyde removal product, and then cooperate with an air purifier, so that the effect will be better.


There are still many differences between air purifiers and dehumidifiers. I hope everyone can choose what kind of machine to improve the indoor air environment according to their actual needs.
