Currently, a crucial component in modern air purifiers is activated carbon filters. The activated carbon in these filters is internationally recognized as a highly efficient adsorption material. As early as World War I, it was used as the primary material in gas masks. Over the years, through continuous improvement and innovation, this material has made significant advancements in both performance and application. Today, the use of activated carbon filters as raw materials in air purifiers is a conscious and informed decision. Why is this so? Let's explore its characteristics to find out. Firstly, activated carbon is a porous carbon-containing substance with a highly developed pore structure.

　　Currently, a crucial component in modern air purifiers is the activated carbon filter. Activated carbon within the filter is internationally recognized as a highly efficient adsorption material. As early as World War I, it was used as the primary material in gas masks. Over the years, through continuous improvement and innovation, this material has made significant advancements in both performance and application. The use of activated carbon filters in today's air purifiers is a conscious and informed decision. Why is this so? Let's explore its properties to find out.

　　First, activated carbon is a porous carbon-containing substance. Its highly developed pore structure gives it a large surface area, allowing it to easily come into full contact with toxic and harmful gases in the air.

　　Second, the activated carbon filter in the air purifier has 1.5 times less resistance than previous products on the market and also incorporates cold catalysis technology for the catalytic decomposition of toxic gases such as formaldehyde.

　　Third, its physical adsorption primarily targets large-molecule organic gases (such as benzene and other TVOCs) by adsorbing these large-molecule pollutants through the microporous structure of the activated carbon itself.

　　Fourth, small-molecule gases easily desorb after adsorption, leading to secondary pollution. Therefore, chemical treatment of the activated carbon is necessary to cause the adsorbed gases to react with the chemical components, thereby achieving the adsorption effect.

　　In summary, activated carbon filters have extremely strong adsorption capabilities. They adsorb large-molecule pollutants in the air through the microporous structure of the activated carbon itself, and are also the primary technology used in air purifiers to remove gaseous pollutants.
