**preventing bacteria viruses and cross infection **individually packing **An 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.

However, even a properly fitted N95 respirator does not completely eliminate the risk of illness or death.
