PM 2.5 Preventable (Surgical Mask)
The PM2.5 surgical masks were originally designed for those living in areas with high air pollution levels.
- PM2.5 masks provide very good filtration (62%-65%), though not as much as N95/KN95 masks.
- The fit on surgical masks is oftentimes loose and does not create a seal around the face. However, the design of these masks primarily sends air upwards to minimize the spread of microscopic particles. Additionally, they typically feature a metal piece at the top that can formed to the bridge of the nose for a more secure fit.
