Foreign air purifiers are not suitable for China's pollution situation

　　Most consumers tend to choose foreign brands when buying air purifiers, believing that they are of better quality, and some even go abroad to buy purifiers exclusively. However, Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Protection Product Quality Supervision and Inspection Center, reminded that most of the air purifiers purchased abroad have problems such as different environments, high prices, and the inability to replace the filter elements in China.

　　Most foreign countries are chip purifiers "80% of the air purifiers in foreign markets are chip purifiers, and most of the chip purifiers are designed for low-pollution air quality abroad, and the material has a small dust holding capacity, which is not suitable for Chinese air purifiers. Pollution situation.” Director Song Guangsheng said that the degree of air pollution abroad is relatively low, while domestic air pollution is not only polluted by particulate matter such as PM2.5, but also indoor decoration, furniture leather and other pollution. At present, most of the advertised in the market are foreign standards, which may not be suitable for China's air environment.

　　It is difficult to solve the problem of after-sales products. Many standards of foreign purifiers are inconsistent with domestic ones. After the filter element fails, it is difficult to find a place to replace the filter element in China, or to replace the filter element with different standards, which affects the quality of the purifier. Song Guangsheng said that the lack of suitable filter elements in China has caused many people to buy purifiers abroad and then idle them for a long time.

　　When choosing an air purifier, you must clarify your own needs. Director Song emphasized that when consumers buy an air purifier, it is necessary to clarify whether the main purpose of the purchase is to remove formaldehyde, or remove dust, or both. Because the price of different products and the materials used are different, it is necessary to select products purposefully. For example, in a newly renovated house, there are many chemical pollutants such as formaldehyde and benzene, and a purifier that removes formaldehyde should be selected; and areas with severe haze need to choose an air purifier that can remove PM2.5.
