How To Select An N95 Respirator Masks For Coronavirus Prevention

An N95 respirator is a respiratory protective face mask, designed to help reduce the person’s exposure to airborne particles together with very small particles (0.3 microns) and huge droplets. N95 respirator face masks actually has a filtration effectivity of no less than 95% against non-oily particles.

2. Variations between N95 masks and surgical mask?

An N95 particulate mask blocks at the least ninety five % of very small (0.3 microns) test particles, and while a disposable surgical mask is fluid-resistant and protects the person against giant particles (5 microns), droplets, sprays or splatter.

Completely different from a loose-fitting, disposable surgical masks, an N5 masks is tight-fitting to achieve a really close facial fit, which ensures a minimal leakage around the edges of the masks when the person inhales. If properly fitted, the filtration capabilities of N95 respirators exceed these of disposable surgical face masks.

Talking of the N95 mask value and disposable surgical masks price, the N95 respirator mask is pricier than a surgical mask. In contrast, the N95 mask is reusable but the common surgical masks is disposable.

Truly, both the N95, KN95, FFP2 and KF94 respirators have nearly the identical filtration efficiency, it signifies that KN95, FFP2, and KF94 are as effective because the N95 respirator mask. The main difference between these respirators is that they are tested by completely different nations.

The N95 masks has a full name of NIOSH-licensed N95 respirator, which means these respirators are tested of ninety five% filtration and certified by the U.S. National Institute of Occupational Safety and Health (NIOSH).
