AIR PURIFICATION
After the Industrial Revolution, many regions in the world vigorously developed heavy industries, resulting in plummeting air quality and serious threats to human health, including the famous "Los Angeles Photochemical Smog Incident". In order to improve air quality, in addition to introducing long-term air control policies, many scientific research institutions are also actively developing air purification technologies to bring consumers a healthy breathing experience in the first place. Of course, these technologies were not initially used in cars. After a long period of concept change, when people realized that the air in the car is also seriously polluted, the car air purification technology specifically for cars has gradually gained attention.
