KN95

Chinese mask standard

KN95 is a Chinese certification standard for respirator masks, roughly equivalent to the American N95.

Both filter at least 95% of airborne particles.

KN95 masks became widely available during the COVID-19 pandemic when N95 supplies ran short: I couldn't find N95s, so I bought KN95s instead.
