KN95 Respirators

KN95/N95 Respirators

V-Guard’s KN95/N95 Respirators, with a filtration capacity of 95%, are made of a fine mesh of non-woven polypropylene fabric with different layers of unique hydrophobic and hydrophilic properties. The inner layer made by a unique melt blowing technique filters out viruses, bacteria, and other hazardous particles.
