With the acceleration of society, industrialization and deepening of urbanization, air quality has increasingly become the focus of attention. Facing the health risks caused by air pollution, air purification technology is widely used as an effective solution. However, there is a misunderstanding in some public opinion that "air purification will pose a new threat to the environment". This paper aims to clarify this view and discuss the relationship between air purification and environmental protection.

First of all, it needs to be clear that the original intention of modern air purification technology is to reduce or remove harmful substances in indoor air, such as PM2.5, formaldehyde and other pollutants, so as to protect people's respiratory system from damage. These technologies include, but are not limited to, HEPA filters, activated carbon adsorption, photocatalytic oxidation and other methods. They capture and decompose pollutants by physical or chemical means without secondary pollution. Therefore, in principle, the rational use of air purification equipment will not only bring extra burden to the environment, but also help to improve the air quality in local areas.

Secondly, on the issue of energy consumption, there are indeed voices that some high-efficiency air purification devices may consume more power resources. However, with the progress of science and technology, more and more energy-saving products have emerged, such as innovative solutions such as air purification systems powered by solar energy, which are gradually becoming popular. In addition, compared with the cost of human disease treatment and the loss of social productivity caused by air quality problems, it is very worth promoting to appropriately increase energy input for maintaining a good living and working environment.

Furthermore, for friends who are worried about the waste disposal problems in the purification process, many responsible enterprises have adopted recycling methods to deal with waste filter screens and other problems, reducing the possibility of environmental pollution. At the same time, consumers can also choose products made of easy-to-recycle materials and participate in the green consumption action together.

To sum up, the statement that "air purification will pose an environmental threat" is not valid. On the contrary, the correct and reasonable application of air purification technology can not only effectively improve people's quality of life, but also promote environmental sustainable development to a certain extent. Of course, this does not mean that we can ignore the importance of source control, and measures such as controlling industrial emissions and optimizing traffic structure are equally indispensable. Only by taking a multi-pronged approach can we truly realize the beautiful vision of harmonious coexistence between man and nature.
