First, the concept of air purifier

Air purifier is also called the machine, the air cleaner, fresh air purifier, refers to the adsorption and decomposition or transformation of various air pollutants (generally include PM2.5, dust, pollen, peculiar smell, formaldehyde, decoration pollution, such as bacteria, allergens, etc.) of the product, it can effectively improve the cleanliness of the air, mainly divided into residential, commercial, industrial and building.

There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies are: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, super-structure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; Material technology mainly includes photocatalyst, activated carbon, synthetic fiber, HEPA efficient material, anion generator and so on. Existing air purifiers are mostly compound, that is, a variety of purification technologies and material media are used at the same time.

In recent years, the air purifier industry has developed rapidly. Although the air purifier industry is developing rapidly at present, in terms of penetration rate, the penetration rate of air purifiers in American households is 27%, 17% in Japan, and about 1% in China. Visible, China's air purifier market still has considerable space for development. On the other hand, the state of indoor environmental knowledge popularization, strengthen the control of environmental quality, and introduced a series of measures, so that the rapid development of environmental protection industry, but also the rapid development of indoor pollution industry chain (indoor pollution detection, treatment, air purifier, fresh air system, etc.).

Second, air purifiers are supported by relevant national policies

Released in August 2016, the ministry of light industry development plan (2016-2020) "clearly pointed out:" the development of intelligent energy saving variable frequency electrical home appliances, health hutch defends electric appliance, smart toilet, air source heat pump air conditioner, large-capacity refrigerators and washing machines, air purifier and water purifiers high-quality electrical appliances product, meet the needs of the consumption structure upgrade." In recent years, The export scale of air purifiers in China has grown rapidly. According to the statistics of the General Administration of Customs of China, the export amount in 2017 and 2018 was stable, respectively 13.928 billion yuan and 12.450 billion yuan. In 2019, the export amount showed a jump growth to 21.858 billion yuan.

Iii. Analysis of the development status of air purifier industry

In recent years, both sales volume and sales volume of Air purifier industry in China have declined. In 2020, the sales volume of air purifiers in China was 3.795 million, down 18.5% year on year. Sales were 6.26 billion yuan, down 31 percent year on year. Under the impact of the epidemic in 2020, the increasing importance of residents on health will drive the demand for air purifier products. In 2021, the decline of the industry will be narrowed. It is estimated that the sales volume of air purifiers in China in 2021 will be 3.684 million units, down 2.9% year-on-year. Sales reached 5.74 billion yuan, down 8.3% year on year. Due to the impact of COVID-19 in 2020, the offline sales market of China's air purifier industry suffered a big impact, with its sales falling by 65% year-on-year to 1.45 billion yuan. In the worst period of the epidemic in 2020, the sales volume of online channels surged under the influence of residents' increasing demand for air quality. However, with the effective prevention and control of the epidemic in China, the sales volume of online channels also fell. In 2020, the annual sales volume of online channels reached 4.81 billion yuan, down 3% year on year. But on the whole, the online market has become the mainstream sales channel of the industry in 2020, and occupies an absolute advantage, accounting for 76.8% of the total sales of the industry.

Fourth, the future development trend of air purifier

With the development of Internet of things and big data, smart home products are favored by more and more consumers for their humanization and ease of operation. "Consumer Goods Standards and Quality Improvement Plan (2016-2020)" requires to adapt to the high-end and intelligent development trend of household appliances, improve the depth of intelligent level of household appliances of various varieties and brands, and promote the rapid development of smart home. Smart home becomes the mainstream of the future development of the industry.

According to the White Paper on China's purifier Industry in 2019, the main pain points of users of air purifiers include poor experience and unknown purification effect. Intellectualization is not only the intellectualization of man-machine interconnection, but also the intellectualization of detection and display. The intelligentization of air purifier helps to improve user experience, timely display the purification effect of products, and realize the visualization of the operation process of air purifier, so as to better serve consumers. Therefore, the future air purifier will develop to the direction of intelligent products.
