What type of mask is specifically designed to filter airborne particles?

The N-95 mask is specifically designed to filter airborne particles, providing a higher level of protection compared to other types of masks. It is a tight-fitting respirator that is capable of filtering out at least 95% of very small (0.3 micron) particles from the air, including various infectious aerosols. This makes it particularly effective in healthcare settings where exposure to pathogens is a concern.

In contrast, surgical masks are primarily designed to protect the wearer from large respiratory droplets and to prevent the spread of infection from the wearer to others. They do not provide the same level of filtration for smaller airborne particles. Dust masks, while they may offer some basic filtration, are generally not designed for medical use and do not meet the rigorous standards required for respiratory protection. Face shields offer a physical barrier and protection to the face but do not filter airborne particles, making them less effective in preventing inhalation of infectious agents.

The design and filtration capability of the N-95 mask make it essential for healthcare professionals and others in environments where airborne transmission of infections is a risk.
