In recent years, air pollution has become more and more serious, and smog has appeared frequently. At the same time, with the rapid economic development, automobiles have become an indispensable means of transportation for the public. As a result, not only indoor air pollution is gradually increasing, but the air quality inside cars exposed to urban traffic and road pollution is even more worrying. Nowadays, people pay more and more attention to indoor and car air quality. In addition to particulate matter (such as PM2.5, PM10), bacteria, odors and other pollutants in the air, in order to prevent secondary pollution of the outside air, people will stay in a closed space for a long time.
