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: A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N2. The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.

Abstract: A filter assembly is disclosed that has a body defining a cavity and having a first side edge surface, a second side edge surface, a top edge surface, and a bottom edge surface forming a perimeter surface around the cavity. A porous flow face extends across the cavity and is coupled to the perimeter surface. The porous flow face arcs between the first side edge surface and the second side edge surface. An adsorbent is disposed in the cavity.
