Designed to deliver an exceptional fit, this half-face elastomeric rubber respirator is priced to be disposable, but can easily be used up to 30 times. A textured, nonslip face seal prevents the mask from moving, maintaining a proper fit during use. The rolled sealing area gently conforms to a wide variety of facial features. A strategically positioned, corrugated exhalation valve helps eliminate dead air to enhance wearer comfort. The unique Saf-Twist connection system lets you attach cartridges in three different positions to maximize compatibility with eye and face protection (masks available with or without cartridges included). Available sizes: Small/Medium and Medium/Large.
