• Patients with respiratory infectious diseases or those with symptoms of respiratory infectious diseases are recommended to wear N95 or KN95 and other particle protection masks (without breathing valve) or medical protective masks.


  • Wearing masks scientifically is an effective measure to prevent respiratory infectious diseases. This guideline is formulated to guide the public to wear masks scientifically and effectively protect public health.


  • One of the most important features to consider is the level of filtration provided by a mask. Masks are rated based on their efficiency in filtering out particles of different sizes, measured in microns. Surgical masks, for example, offer relatively low filtration, typically around 70-80%, but are still effective at preventing respiratory droplets from spreading. N95 masks, on the other hand, are designed to filter out at least 95% of airborne particles, including small particles such as those found in smoke or air pollution.


  • Medical masks have become an indispensable protective equipment in our daily lives. They not only help us resist the invasion of viruses, but also become the guardians of medical staff and volunteers.


  • As the COVID-19 pandemic continues to spread across the globe, protective face masks are becoming a common sight. People are wearing them at work, while shopping, and even during outdoor activities. Although masks may feel uncomfortable or inconvenient at first, they offer several advantages in the fight against this virus.


  • As businesses reopen around the world and people return to work, the importance of N95 masks in preventing the spread of COVID-19 cannot be overstated. At this critical juncture, it's imperative to understand the advantages of N95 masks and why they are so effective.
