Abstract
A filtering respirator in the form of a mask has an outer casing and a filter layer inside the casing. The edge of the filter liner is sealed to the casing and the rest of the filter layer is spaced from the casing to provide an interspace between them which is connected with the outside atmosphere by an opening in the casing so that exhaled air will leave the mask at a velocity sufficient to prevent inhaling of the exhaled air.
