Abstract

A facemask includes air-permeable filtering media for positioning over a wearer's nose and mouth, and peripheral portions adapted to fit the facemask to a wearer's face. The peripheral bottom portion includes an elongate elastic member anchored at its ends to the peripheral bottom portion proximate to or coincident with the opposing side portions and having a length in an extended state extending substantially across a width of the ungathered peripheral bottom portion. The elongate elastic member further includes an unattached portion between the anchored ends, which freely extends and relaxes without constraint to gather the peripheral bottom portion for engaging a chin and face of a wearer during use. The gathered peripheral bottom portion provides an air-inhibiting seal between the air-permeable filtering media and a wearer's face.
