First, identify the main obstacles to air purification

1. Technical obstacles: Although there are many air purification technologies and products on the market at present, not all technologies are mature and reliable, and cost-effectiveness is also an important consideration.

2. Economic obstacles: For many families and individuals, the cost of purchasing high-efficiency air purification equipment may be too high; For the government, large-scale promotion of advanced air purification technology also needs huge financial support.

3. Consciousness obstacle: The public's lack of awareness of the dangers of air pollution and sufficient awareness of environmental protection directly affects the motivation of individual behavior change and the overall action of society.

4. Policy obstacles: Although many countries and regions have issued a series of regulations and standards on improving air quality, there are still shortcomings in terms of enforcement and supervision mechanism.

Second, effective strategies to overcome obstacles to air purification

Increase technology research and investment: encourage and support scientific research institutions and enterprises to carry out technological innovation and develop more low-cost and high-performance air purification solutions.

Provide financial subsidies and tax incentives: reduce the cost threshold of using clean energy and technologies by providing financial subsidies to families and individuals who buy green energy products and services, and giving tax breaks for enterprises to develop environmental protection technologies.

Strengthen publicity and education: use the media platform to popularize scientific knowledge, improve citizens' environmental awareness and sense of responsibility, and stimulate the enthusiasm of all sectors of society to participate in environmental protection activities.

Improve the system of laws and regulations: establish and improve relevant legal systems, clarify emission standards, strengthen law enforcement supervision, and ensure the effective implementation of various policies and measures.

Third, the conclusion

In the face of various obstacles in the process of air purification, we need to make comprehensive policies and work together from multiple angles. Only in this way can we truly achieve a fundamental improvement in air quality and protect our home on earth. In the future, with the progress of science and technology and the active participation of all walks of life, I believe that mankind will be able to overcome difficulties and usher in a fresher and more pleasant living environment.
