ABSTRACT:
A face mask having a mask body made of a shaped first material with an opening and a reduced resistance filter material placed within the opening. The reduced resistance filter material permitting air to flow relatively freely there through. In one embodiment one edge of a shield is fixed to the mask body of the face mask and covers the opening and the reduced resistance filter material protecting the opening from liquid splashes and the exhaled air flow from a user downwards, away from the user's eyes. Exhaled air from a user wearing the face mask is caused to relatively freely flow through the reduced resistance filter and to be directed downward preventing the fogging of a user's eyewear. The face mask of the present invention is particularly suited to the medical and dental profession.
