PM2.5 mask standard will introduce activated carbon mask to prevent PM2.5

As autumn and winter approach, the concentration of pollutants in the air rises, leading many individuals with sensitive skin to wear "PM2.5" masks for protection. However, some consumers are questioning the quality and effectiveness of these masks. According to recent reports, a new PM2.5 mask standard is expected to be introduced soon, aiming to improve product safety and reliability. A reporter recently visited several large shopping malls and wholesale markets, as well as checked multiple online retail platforms. He found that masks labeled as "PM2.5" are widely available on the market, coming in various types such as particulate-resistant, formaldehyde-protective, odor-blocking, and activated carbon masks. Upon closer inspection, it became clear that each mask operates on a different protective principle, but many lack essential information like manufacturer details or material composition. Many of the masks were packaged in simple plastic bags, emitting an unusual smell. In one wholesale market, the reporter noticed that some masks featured colorful cartoon designs, which might appeal to children but raise concerns about their protective function. Some activated carbon masks even claimed to block PM2.5, yet their production process was minimal—just a thin layer of activated carbon applied to the filter. This method relies on basic physical adsorption, which is not sufficient for filtering fine particles like PM2.5. Experts have warned that while activated carbon masks can effectively absorb harmful gases such as benzene and formaldehyde, they do not provide a reliable barrier against fine particulate matter. In fact, activated carbon itself can release tiny particles, which may be inhaled by the wearer and pose a risk to those with chronic respiratory conditions or weakened immune systems. These masks are more suitable for indoor use, such as deodorizing after home renovations, rather than protecting against PM2.5. A representative from Green Shield, a PM2.5 mask manufacturer certified by Nilsson Laboratories and the National Labor Protection Products Quality Supervision and Inspection Center, explained that their patented PM2.5 mask uses a specialized microfiltration system. This technology achieves a filtration efficiency of up to 99%, significantly reducing the pressure difference across the filter compared to traditional masks. As a result, breathability is improved, and the common issue of breathing difficulty in conventional masks is addressed. Air pollution poses serious health risks, primarily through "two fine" factors: fine particles like PM2.5 and airborne pathogens such as H1N1, H5N1, and MRSA. These microscopic elements can enter the body through the respiratory system, causing a range of respiratory and internal diseases. Currently, two standards—“Anti-bacterial Daily Masks” and “Anti-bacterial Non-woven Masks”—have been approved by quality supervision authorities and are expected to be upgraded to industry or national standards in the near future.
