3M PAPR (powered air-purifying respirator) protection plates, lenses, and lens covers attach to PAPR headgear of the same brand and series. Lenses protect the eyes and prevent ambient air and contaminants from entering the headgear. Lens covers protect the front of the lens. They are removed and replaced when wear affects visibility. Plates hold the lens in place.
