Surgical masks are fluid-resistant, disposable, and loose-fitting devices that create a physical barrier between the mouth and nose of the wearer  
The side of the mask that has a stiff bendable edge is the top and is meant to mold to the shape of your nose. Determine which side of the mask is the front. The colored side of the mask is usually the front and should face away from you, while the white side touches your face.
