With the progress of science and technology and the improvement of people's quality of life, more and more people begin to pay attention to air quality. From smog, automobile exhaust to industrial pollution, pollutants in the air are everywhere, which poses a great threat to people's health. In this context, air purification has gradually become the focus of social attention, and various new technologies are constantly emerging, which has promoted the rapid development of air purification. This paper will discuss some new trends of environmental protection in the field of air purification.

First, the application of green materials

In recent years, using natural or degradable materials as filter materials has become one of the research and development hotspots. For example, bamboo charcoal and activated carbon are widely used in household and car air purifier because of their good adsorption performance; However, some plant fibers are used as filter media in some specific situations because of their pro-environment characteristics, which can not only effectively purify the air, but also reduce the impact on the environment.

Second, the development of intelligent technology

With the help of Internet of Things technology and big data analysis, modern air purification equipment is developing in a smarter direction. Users can remotely control the air purification device at home through the mobile APP, check the indoor PM2.5 concentration and other data in real time, and automatically adjust the working mode according to the actual situation, so as to achieve high efficiency and energy saving and improve the user experience.

Third, multi-functional integrated design

In addition to the basic functions of dust removal and deodorization, the new generation products also integrate various additional functions such as humidification and sterilization. For example, ultraviolet lamp irradiation is used to kill bacteria and viruses, or a large number of negative oxygen ions are released by negative ion generator to improve the quality of living environment. These innovative design concepts enable a single product to meet the diverse needs of consumers.

Fourth, the popularity of public space

In addition to domestic use, public places such as schools, hospitals, offices and other places have begun to gradually install professional large-scale air purification systems. This not only helps to protect special people from harmful substances, but also provides a safer and more comfortable living environment for all users.

In short, in the face of the increasingly severe air pollution situation, each of us should take active actions and choose the way that suits us to participate in this "breathing defense war". In the future, more advanced technologies and concepts will be applied and popularized, and it is believed that air quality will be significantly improved, and human beings will also enjoy fresher air resources.
