2018年，中国空气净化设备市场规模达75亿元，居世界第一。 但是，人均占有率不到1％，市场发展潜力巨大。 但是，空气净化设备行业存在的问题是不规范，认证不规范，数据不规范，价格和宣传混乱。 如何规范净化设备行业的发展，需要政府和企业的共同努力。
In 2018, China's air purification equipment market reached 7.5 billion yuan, ranking first in the world. However, the per capita share is less than 1%, and the market has great potential for development. However, the problems in the air purification equipment industry are not standardized, certification is not standardized, data is not standardized, price and publicity are confused. How to standardize the development of purification equipment industry requires the joint efforts of the government and enterprises.
CADR值（即空气净化设备每小时可输出的清洁空气量）是空气净化产品的核心指标之一，其数据应由权威机构检测。 但是，尽管有些企业已经表明了其价值，但他们尚未获得任何测试报告。 有些只是获得了国外机构的测试结果，他们在国内上市后才公布了它们的价值，它们的价值也非常可疑。
CADR value (i.e. the clean air output per hour of air purification equipment) is one of the core indicators of air purification products, and its data should be tested by authoritative agencies. However, although some companies have demonstrated their value, they have not yet received any test reports. Some have only obtained the test results of foreign institutions, and their value has not been disclosed until they are listed domestically. Their value is also very doubtful.
It is understood that the new national standards for air purification equipment are expected to be formally introduced in the first half of this year, and those enterprises that rely on false propaganda will be eliminated. This requires enterprises to strictly comply with the new standards, or even exceed the national standards, so as to promote the healthy development of the market.
随着对烟雾的深入了解，很多消费者在购买空气净化设备时开始关注CADR值，但深圳市清洁工程公司负责人张明表示，这还不够。 张先生认为，除了我们经常说的固体颗粒物PM2.5外，还存在甲醛，苯，TVOC和氨等气态污染物。 烟尘，过敏原，细菌和病毒也威胁着人们的健康。 因此，消费者应放弃对PM2.5产品的简单过滤，而寻求全面的空气净化工程解决方案。
With the in-depth understanding of smoke, many consumers begin to pay attention to CADR value when purchasing air purification equipment, but Zhang Ming, head of Shenzhen Clean Engineering Company, says that is not enough. Mr. Zhang believes that in addition to the solid particulate PM2.5 which we often talk about, there are also gaseous pollutants such as formaldehyde, benzene, TVOC and ammonia. Smoke, allergens, bacteria and viruses also threaten people's health. Therefore, consumers should abandon the simple filtration of PM2.5 products and seek comprehensive air purification engineering solutions.
