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 people with sensitive skin to wear "PM2.5" masks for protection. However, concerns about the quality and effectiveness of some PM2.5 masks have been growing. Recently, it was reported that a standardized regulation for PM2.5 masks is expected to be introduced soon, aiming to improve consumer confidence. A recent investigation by a reporter revealed that PM2.5 masks are widely available in large shopping malls, wholesale markets, and online stores. These masks come in various types, including anti-particulate, anti-formaldehyde, anti-odor, and activated carbon masks. Each type claims to offer different levels of protection, but upon closer inspection, the protective mechanisms vary significantly. Many masks lack clear labeling of the manufacturer’s name or the materials used. Some are packaged in simple plastic bags with an odd smell. In one wholesale market, the reporter noticed masks with colorful cartoon designs on the front, which may appeal to younger consumers. Some activated carbon masks are labeled as "anti-PM2.5," suggesting they can trap tiny particles in the air. However, the actual production process often involves simply applying a thin layer of activated carbon powder onto the filter, which relies on basic physical adsorption rather than advanced filtration technology. Experts warn that while activated carbon masks are effective at absorbing harmful gases like benzene and formaldehyde, they do not provide sufficient protection against fine particles such as PM2.5. Moreover, activated carbon itself can release small particles that may be inhaled, potentially harming individuals with respiratory conditions or weak immune systems. Normally, these masks are used for indoor odor control and not for protection against airborne pollutants like 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 99% filtration efficiency, reduces the pressure difference across the filter by about 20 times compared to traditional filters, and significantly lowers breathing resistance. This innovation improves air permeability and addresses the common issue of discomfort in conventional masks. It is also worth noting that air pollution poses serious health risks, primarily through two key factors: fine particles (like PM2.5) and pathogens such as H1N1, H5N1, and MRSA. These microscopic particles and viruses can enter the body through the respiratory system, causing a range of illnesses, from mild irritation to severe lung diseases. Currently, two standards—“Anti-Bacterial Daily Masks” and “Anti-Bacterial Non-Woven Masks”—have been approved by the quality supervision department and are expected to be upgraded to industry or national standards in the near future.
