The “KF” in KF94 stands for “Korean filter,” and the “94” indicates a 94% bacterial filtration efficacy. It is the South Korean equivalent to the N95 mask, with a few differences. It combines elements of an N95 mask with those of a cloth mask, contouring close to the face with an adjustable band around the bridge of the nose. The tentlike shape creates a little pocket of extra space between your mouth and the mask.
