ocial and environmental problems are increasingly prominent, among which air pollution has become one of the important factors affecting people's quality of life. With the acceleration of industrialization and the continuous advancement of urbanization, automobile exhaust and industrial emissions have become the main sources of pollutants. In the face of severe air quality challenges, it is particularly important to explore new purification technologies and environmental protection strategies. This paper will discuss the new direction of air purification and environmental protection from three aspects: technical innovation, policy guidance and social participation.

First, technological innovation leads the future

1. Intelligent monitoring system: Using the Internet of Things technology to build an intelligent air quality management platform to realize real-time monitoring of air quality, and predict pollution trends through big data analysis to provide scientific basis for government decision-making.

2. New filter materials: research and develop air purifier filter materials with high efficiency and low energy consumption, such as nanofiber membranes and photocatalytic materials, to improve the removal effect of fine particles such as PM2.5.

3. Application of green energy: Promote the use of clean energy (such as solar energy and wind energy) to replace traditional fossil fuels and reduce harmful gas emissions at the source.

Second, policy support promotes change

1. Strict laws and regulations: improve the relevant laws and regulations system, increase the punishment for illegal sewage discharge, and ensure the effective implementation of various standards.

2. Financial subsidies and incentives: give certain economic subsidies or tax relief to enterprises that adopt advanced governance technologies, and encourage more enterprises to participate in environmental protection.

3. Public education and publicity: strengthen the cultivation of citizens' environmental awareness, popularize the knowledge of low-carbon lifestyle, and form a good social atmosphere.

Third, the whole people take action to create a better home.

1. Green travel mode: It is recommended to travel by public transport, cycling or walking instead of private cars to reduce the pollution caused by motor vehicles.

　　2. Energy-saving and emission-reduction life: Start with small things in daily life, such as saving electricity and water, reducing the consumption of disposable items, etc., and jointly protect Mother Earth on which we depend.

3. Volunteer service activities: actively participate in various environmental public welfare activities, such as planting trees and cleaning rivers, and improve the surrounding environmental quality with practical actions.

In a word, solving the air pollution problem requires the joint efforts of the government, enterprises and every ordinary citizen. Only with the concerted efforts of Qi Xin can we create a fresher and more pleasant living environment. Let's go hand in hand, while pursuing economic development, don't forget to protect this precious natural resource!
