Surgical Facemask(5Piecies)

Surgical facemasks were originally designed to protect medical personnel from splashes or sprays of bodily fluids, but the effectiveness of surgical masks against influenza-like infections has not been confirmed by high-quality randomized controlled trials. Surgical masks vary by quality and levels of protection. Despite their name, not all surgical masks are appropriate to be used during surgery. Surgical masks may be labeled as surgical, isolation, dental, or medical procedure masks. 
A surgical mask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes, or certain medical procedures. Surgical masks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the face mask and the face.
