The National Center for Public Health has advised citizens to wear N95 filter masks to protect themselves from risks during periods of high air pollution.
N95 filter masks can block 95% of particles sized 2.5 microns or larger. In comparison, regular cloth masks only have a filtration capacity of 51%.
Types of Masks and Their Filtration Efficiency:
| Type of Mask | Filtration Efficiency for Particles 2.5 Microns or Larger |
|---|---|
| N95/FFP2 and Similar Types | 95% |
| Medical Surgical Mask | 89.5% |
| Cloth Mask (2 layers) | 82% |
| Cloth Mask (1 layer) | 51% |
| Mask with Replaceable Filter | 87.1% |
| Scarf | 49% |
Droplet sizes range from 1-100 microns.
