A N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. The 'N95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles. If properly fitted, the filtration capabilities of N95 respirators exceed those of surgical masks.
The N95 respirator and its alternatives are:
i) N95 (United States NOSH-42CFR84)
ii) FFP/CE certified (Europe EN 149-2001)
iii) KN95 (China GB2626-2006)
