N99 | N95 Face Mask Men and Women
Anti Pollution | Activated Carbon | Dust Proof
Disposable P2/N95 / N99 face masks (also known as P2/N95 or N99 respirators) can filter out very fine particles from the air when worn correctly, and so reduce the risk of airborne transmission of Q fever and other infectious diseases when working in potentially contaminated areas.
N99 respirators filter greater than or equal to 99 percent…” In a nutshell, a respirator rated N95 filters out more than 95% of particles (PM) larger than 0.3 microns. This is a good thing, since most of air pollution effects are caused by particles with a size of 2.5 microns and smaller.
N95 respirators. 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.
