With the acceleration of industrialization and urbanization, the problem of air pollution has become increasingly prominent, which has become a major problem that plagues many countries and regions around the world. While enjoying the convenience brought by modernization, people have to face a series of environmental problems arising from it. Among them, the decline of air quality is particularly worrying, which not only affects people's health, but also causes serious damage to the ecological environment. However, in the pursuit of clean air, some environmental protection measures may bring new interference and challenges.

First, the double-edged sword effect of air purification equipment

In order to cope with the serious air pollution, many families and individuals have purchased various types of air purifiers to improve indoor air quality. These devices remove pollutants such as suspended particulate matter (PM2.5) and harmful gases (VOCs) in the air by filtration or adsorption, providing users with a relatively safe and comfortable living space. However, due to the lack of effective technical support, some low-end products may have problems such as high energy consumption and high noise; At the same time, improper use or inadequate maintenance may also lead to secondary pollution, such as bacterial growth and excessive ozone.

Second, the problem of excessive dependence on air purifiers

Although the air purifier can effectively purify the indoor air quality, it has long relied too much on this "passive defense" means, but neglected the importance of reducing pollutant emissions from the source. For example, automobile exhaust is one of the important sources of PM2.5 in cities, and encouraging green travel modes (such as riding, walking and taking public transport) is the fundamental way to solve this problem. In addition, planting trees and flowers on a large scale and increasing the urban greening rate are also effective ways to improve the overall air quality in the region.

Third, the government should strengthen supervision and guidance.

Faced with the above problems, government departments should strengthen the quality supervision of various air purification products sold in the market to ensure that they meet the requirements of relevant standards; At the same time, it is necessary to increase publicity, popularize correct knowledge of purchase and use, and help consumers establish a scientific and reasonable consumption concept. More importantly, it is necessary to formulate and implement stricter environmental protection laws and regulations, promote the adjustment and upgrading of industrial structure, and promote a virtuous circle between economic and social development and ecological protection.

In a word, solving the problem of air pollution requires the joint efforts of the whole society, and we must pay attention to both end treatment and source control in order to realize the real dream of blue sky and white clouds.
