In recent years, smog has become a growing concern, leading to a surge in the demand for protective masks. These include medical, industrial, and consumer masks, which have seen increased sales in pharmacies and online platforms. However, the question remains: which mask can truly protect against smog? So far, there is no clear answer. Some manufacturers have started making bold claims, leaving consumers confused. Industry experts are calling for the establishment of national standards for civilian masks.
The rise in foggy days has significantly boosted the mask market. In 2013, smog affected 25 provinces, with an average of 30 haze days—up by 10.3 days compared to previous years. Southern regions, once known for good air quality, also experienced frequent smog. During the 2013 "two sessions," many provinces focused on addressing pollution. As public awareness of respiratory protection increased, PM 2.5 masks became popular. Online shopping platforms saw a spike in searches for "PM 2.5 masks" and "haze-proof masks."
Masks come in various types, such as those with filter cartridges, activated carbon masks, N95, and KN90. According to e-commerce data, consumers spent 8.7 billion yuan on protective products in 2013, with mask sales rising sharply. On Tmall and Taobao, mask and air purifier purchases increased by 181% and 131%, respectively, compared to 2012.
Green Shield, a domestic mask brand, gained popularity due to its antibacterial fiber and filter technology, claiming to protect against both PM 2.5 particles and viruses. In 2013, Green Shield sold 6.5 million masks, generating 210 million yuan in revenue—4.3 times higher than in 2012. On Singles' Day, daily sales reached 1.29 million yuan, and on December 5, it hit 2.3 million yuan, ranking third in Tmall’s household products category.
However, some concerns have emerged about the safety of industrial masks. A TV program tested various masks using TSI instruments, revealing that N95 and KN90 masks performed well, while activated carbon and filter masks did not effectively block PM 2.5. This led to debates over mask standards.
Zhao Danqing, a representative from Green Shield, criticized the test, suggesting it was biased. He argued that industrial masks, though effective at filtering particles, are uncomfortable for long-term use and may even promote bacterial growth. He emphasized that current standards like GB2626-2006 apply to industrial masks, not civilian ones.
With no official standard for civilian masks in China, the market remains confusing. Many people, including children and pregnant women, end up using industrial masks, which may not be suitable for them. Experts stress the need for clearer guidelines to ensure consumer safety.
Currently, there are no comprehensive studies or regulations defining which masks are best for daily use. While some companies have developed their own standards, they lack national recognition. Without proper oversight, the market continues to be filled with counterfeit products and misleading claims.
As smog persists, the demand for reliable and safe masks will only grow. Until national standards are established, consumers must navigate a complex and often unclear market, relying on limited information to make informed choices.
