With the advancement of industrialization and the acceleration of urbanization, the problem of air pollution has become increasingly serious and has become one of the global environmental challenges. It not only threatens human health, but also seriously affects the ecological balance. Faced with this situation, governments, enterprises and the public all over the world are actively seeking solutions to promote the development and application of air purification technology and strive to build a cleaner and healthier living space.

Present situation of air quality

According to the data released by the World Health Organization, 7 million people die prematurely every year due to air pollution, which is equivalent to 14 people dying every minute. Pollutants such as fine particulate matter (PM2.5) and sulfur dioxide (SO2) are the main culprits, which can penetrate deep into human lungs and even blood, causing respiratory diseases, cardiovascular diseases and other diseases. In addition, air pollution will aggravate the greenhouse effect, accelerate the melting of glaciers, affect crop growth and destroy biodiversity.

Science and technology help purification

In recent years, science and technology have played an important role in improving air quality. For example, HEPA high efficiency filter can effectively remove more than 99.97% of particulate matter in the air; Activated carbon adsorption method can absorb harmful gases such as formaldehyde, benzene and other volatile organic compounds; Photocatalyst technology decomposes pollutants by using free radicals generated under ultraviolet irradiation. These innovations have been widely used in household air purifiers, automobile exhaust gas treatment devices and large industrial exhaust gas treatment facilities, which have significantly improved air quality.

Policy Guidance and Social Participation

In addition to technological innovation, policy regulation and social action are equally indispensable. Many countries and regions have introduced strict emission standards, and restricted the expansion of highly polluting industries and encouraged the use of clean energy through legislative means. At the same time, improving citizens' awareness of environmental protection is also the key. More and more people begin to pay attention to the impact of their actions on the environment, choose low-carbon travel mode, reduce the consumption of disposable plastic products, actively participate in afforestation and other activities, and jointly contribute to creating a beautiful blue sky.

In a word, air purification is a complicated but necessary task. We look forward to seeing more effective measures and technologies in the future, so that Mother Earth can be rejuvenated and everyone can breathe freely in the fresh air.
