Abstract: This disclosure describes filter media and mask filters and face mask systems including those filter media. In one aspect, the filter media includes a fibrous media including multi-component binder fibers, glass fibers, and microfibrillated cellulose fibers. In some aspects, the fibrous media further includes PET fibers. In another aspect, the filter media includes an electrostatically charged filter media, a fine fiber layer, and a scrim. In yet another aspect, the filter media includes two fine fiber layers, and two scrims. In additional aspects, the filter media includes bicomponent fibers, polyethylene terephthalate fibers, and microfibrillated cellulose fibers. In a further aspect, the filter media includes a support layer, a continuous fine fiber layer, and an efficiency layer. Combinations and composites of the filter media are also contemplated.

Abstract: This disclosure describes a filter medium that minimizes the adverse effects of variations in flow rate on filter medium efficiency without a corresponding increase in pressure drop. The filter medium includes a support layer, a continuous fine fiber layer, and an efficiency layer. The continuous fine fiber layer includes a continuous fine fiber that has a diameter of up to 10 micrometers and is located downstream of the efficiency layer.
