Best Masks for Air Pollution
Masks filter particles when fit tightly. They are a backup when you must go outside during high AQI — not a substitute for staying indoors during hazardous smok
Masks filter particles when fit tightly. They are a backup when you must go outside during high AQI — not a substitute for staying indoors during hazardous smoke.
What works
N95, KN95, or FFP2 rated for particles — not cloth masks alone. Check AQI before long outdoor exposure; masks are uncomfortable for running.
Fit, seal, and when masks stop helping
A mask only filters air that passes through the material — any gap around the nose or jawline lets unfiltered air in, which is why a proper seal matters more than the filter rating on paper. Facial hair, poorly sized masks, and glasses that fog are common seal-breakers worth addressing before relying on a mask outdoors.
Masks reduce inhaled particulate exposure but do not filter gaseous pollutants like ozone or nitrogen dioxide, and they add breathing resistance that makes sustained exercise harder. On hazardous AQI days, the more reliable choice for sensitive groups is to avoid prolonged outdoor exertion altogether rather than mask through it.
