Data shows that in 2014, the domestic air purifier market retail volume reached 5.8 million units, with a sales value of approximately 13.6 billion yuan; it is estimated that the air purifier sales volume will reach 9 million units in 2015, with sales exceeding 20 billion yuan.

    

　　Faced with a wide variety of air purifier products on the market, the customer service staff of Chuanglan air purifier told reporters that the basic principles of choosing an air purifier are: one is non-toxic and harmless, the other is effective, and the third is safe, which is currently the mainstream on the market. The purifier is a HEPA filter + activated carbon type.

　　When purchasing an air purifier, the most important consideration is "effective". Industry insiders suggest that products with third-party inspection certificates should be the first choice, preferably with a certain medical background, and secondly, brands that are more secure in service and after-sales should be selected (because the subsequent filter replacement requires long-term maintenance).
