Transparent Facemask Fabric (Reusable Nosebridge)


ChemStat 929 Plus is designed to prevent your most important equipment from overheating – your people.

ChemStat 929 Plus is a transparent face mask material so sheer workers can read lips through it. Facial features are easily recognized. The pressure differential is zero so that speaking and hearing are unimpaired. Noxious elements of a worker’s breath that would cause discomfort over long periods are not retained. Even with a micron rating lower than that of a facial hair or skin flake, it lets people breathe freely.

Like other ChemStat fabrics, ChemStat 929 Plus is 100% polyester and is therefore universally laundered and sterilized, including gamma radiation.

The upgrade to ChemStat 929 Plus incorporates a 45% reduction in pore size for greater filtration effectiveness.
