Abstract

A disposable respirator (10) including peripheral bindings of filter material providing breathable filter protection along the periphery of the respirator, portions of that periphery (34, 36) being set against the face of the wearer. The respirator further includes filter material (32) pleated a plurality of times and set away from the face of the wearer by lengths of ultrasonically welded or heat sealed side welds (16, 18). The additional pleats advantageously provide high filtering surface area and a low filtering load across the periphery and pocket of the respirator. The result is superior breathability and comfort.
