In the process of rapid industrialization, air pollution has become one of the important factors restricting the sustainable development of social economy. With the enhancement of people's awareness of environmental protection, air purification technology has developed rapidly, but there are still many problems to be solved. This paper will discuss the environmental defects of air purification technology from the aspects of purification equipment efficiency, energy consumption and resource utilization, and put forward suggestions for improvement.

First, improve the purification efficiency and effect

At present, HEPA high-efficiency filter is widely used in air purifiers on the market for physical interception. Although it can effectively remove particulate matter, its adsorption capacity for harmful gases such as formaldehyde is limited. It is suggested to develop new composite filter materials, such as activated carbon-molecular sieve combined materials, to improve the simultaneous removal rate of various pollutants; At the same time, the air duct design is optimized to ensure that the air flow is evenly distributed over the whole filtering area, so as to avoid blockage or leakage caused by local overload.

Second, reduce energy consumption and realize low-carbon operation

At present, most household air purification devices consume a lot of electricity when working, which is not conducive to achieving the goal of energy saving and emission reduction. In the future, we should pay attention to developing energy-saving products, such as automatically adjusting power output according to indoor air quality changes through intelligent control chips to reduce ineffective power consumption; Or introduce solar photovoltaic panels as an auxiliary power supply mode to reduce the pressure on the power grid.

Third, recycling reduces waste generation

The traditional disposable filter element not only increases the use cost of users, but also causes a lot of plastic waste accumulation. In this regard, we can consider promoting clean and reusable environment-friendly filter materials, establishing a perfect recycling mechanism, and encouraging consumers to actively participate in the old parts returning to the factory for maintenance, thus prolonging their service life and reducing the environmental burden.

Fourth, strengthen supervision and promote the development of industry norms

Relevant government departments need to strengthen the inspection of the quality and safety performance of air purification products, establish and improve relevant laws and regulations, and crack down on the behavior of counterfeit and shoddy goods entering the market to disturb the normal order. In addition, it is necessary to regularly carry out popular science propaganda activities, popularize scientific purchasing knowledge, guide the public to establish a correct consumption concept, and jointly safeguard a good ecological environment.

In a word, we should take comprehensive measures to improve the existing air purification technology, not only to pursue technological innovation breakthrough, but also to give consideration to economic and social benefits, and finally realize the beautiful vision of harmonious coexistence between man and nature.
