Social and environmental problems have become one of the focuses of global attention. With the acceleration of industrialization and the continuous advancement of urbanization, air pollution has become an important factor restricting sustainable development. Faced with this challenge, how to effectively reduce air pollutant emissions and improve air quality has become a common topic of discussion in all walks of life. The purpose of this paper is to explore the obstacles and solutions in the process of air purification, in order to contribute wisdom to building a greener and healthier ecological environment.

First, the importance of air purification

Air is one of the indispensable basic conditions for human survival, and clean air is the key to maintaining human health. According to the statistics of the World Health Organization, the number of deaths caused by air pollution is as high as 7 million every year. Therefore, taking measures to improve air quality is not only related to public health, but also an important basis for promoting sustained and healthy economic and social development.

Second, the main obstacles facing air purification

1. Technical problem: Although there are many air purification technologies and products on the market at present, there are still some limitations in effectively removing harmful substances such as fine particulate matter (PM2.5).

2. Cost considerations: For enterprises and individuals, investing in efficient air purification systems or equipment often requires high initial investment, which may become an important factor hindering its wide application.

3. Lack of awareness: Some people don't have a deep understanding of air quality and lack the will to take active actions to protect themselves and the surrounding environment.

4. Limited policy support: Although many countries and regions have issued a series of regulations and guidelines on air pollution control, the specific implementation efforts and effects still need to be strengthened.

Third, strategic suggestions to overcome obstacles

Increase investment in scientific research: The government and all sectors of society should increase their support for the research and development of air purification technology, encourage innovation and reduce the cost of technology application.

Popularize education and publicity: strengthen publicity and education for the public through various channels such as the media, and enhance the public's understanding of the importance of environmental protection.

Improve laws and regulations: formulate stricter and operational legal provisions to regulate enterprise behavior, and provide necessary financial subsidies and technical assistance to promote industrial transformation and upgrading.

Advocate low-carbon life: encourage and support the use of clean energy vehicles to reduce fossil fuel consumption; At the same time, promote the concept of green building and optimize indoor air quality by means of natural ventilation.

In short, to achieve the goal of "less air purification obstacles", we need to work together from multiple angles, not only to solve the technical bottleneck problem, but also to enhance people's awareness of environmental protection, and more importantly, to have strong policy measures as support. Only in this way can we build a truly green ecological home.
