Our Preserve-A-Mask™ Face Shield provides a barrier for medical workers working in environments where there is a risk of exposure to fluids to face or masks. Each one is constructed of non-porous PVC, vinyl and nylon and can be cleaned, sanitized and reused. It helps to provide face and eye protection from fluids as well as preserve the usability of face masks. It's designed with three formed brow pads that extend 1" from forehead with upper vent slots to enhance comfort, increased airflow and visibility by reducing condensation and fog. The adjustable tab secures shield in place.
