What type of mask is known for being effective against dust and mists?

The N-95 mask is designed to provide a high level of filtration, effectively filtering out airborne particles, including dust and mists. This mask is constructed to achieve a fit that prevents unfiltered air from entering around the edges. The designation "N95" indicates that the mask can filter out at least 95% of very small (0.3 micron) particles, making it particularly useful in environments where exposure to fine dust and aerosols is a concern.

In contrast, standard surgical masks primarily serve as a barrier to protect others from the wearer's respiratory droplets and do not have the same level of filtration efficiency. Cloth masks can offer some degree of protection but vary greatly in effectiveness depending on the material and layers used, often not being rated for specific particulate filtration. Ventilated masks may provide comfort and airflow but are not specifically designed for filtration against dust and mists. Thus, the N-95 mask is the most suitable choice for protecting against these airborne particles.
