Effectiveness and Limitations of N95 Masks in Protecting Against Air Pollution
N95 masks can effectively reduce exposure to fine particulate matter like PM2.5 when worn properly with a good fit, blocking about 95% of airborne particles. Studies indicate health benefits such as improved cardiovascular markers and reduced airway inflammation. However, their protection is limited to particles and does not extend to gases or vapors found in smog. Experts emphasize that masks are not a substitute for minimizing outdoor exposure during severe pollution episodes.
