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.

Abstract: This disclosure describes a high performing (including, for example, high efficiency and low pressure drop) filter media. The filter media includes a support layer and a layer of fine fibers wherein at least some of the fine fibers in the fine fiber layer having an average diameter at least 3 times the average fiber diameter of a smaller fine fiber in the fine fiber layer. The fine fiber layer may include multiple layers of fine fibers. In some aspects, the smaller fine fiber may be present in the same layer of fine fibers as the larger fine fibers. Additionally or alternatively, the larger fine fibers may be present in a first layer of fine fibers and the smaller fine fibers may be present in a second layer of fine fibers.

Abstract: Filter arrangements include a barrier media, usually pleated, treated with a deposit of fine fibers. The media is particularly advantageous at high temperature (greater than 140°F) systems. Such systems may include engine systems and fluid compressor systems. Filter arrangements may take the form of tubular, radially sealing elements; tubular, axial sealing elements; forward flow air cleaners; reverse flow air cleaners; and panel filters.
