Surgical face masks are intended to be used by healthcare workers and carers for sick patients with respiratory infections.

Physical form

A surgical mask usually consists of three-ply (three layers). The outer layer of the mask is commonly made of non-absorbent material that acts as water repellent. The middle layer acts as a filter which is made of non-woven material. Lastly, the inner layer is made of absorbent material such as cotton for moisture absorption.
