A KN95 Respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. The KN95 designation means that when subjected to careful testing, the respirator blocks at least 95% of small (0.3 microns) test particles. Made from the softest material, the face mask can be worn with ease for all sizes of face and head and is comfortable even for prolonged wearing. No N95 masks are washable or reusable. Re-using brings down protection drastically. Ideal to protect you when you are out and about, eg in public transport, buses, metro trains, hospitals, offices, malls, cinema halls, social gatherings, religious places, and so on.
