<p>Provided is a mask with a nasal cushion, the mask consisting of a filter that filters dust, wherein the edges of the filter are folded back to create flaps that follow the depressions on both sides of the nasal region. A sponge of urethane foam or the like is affixed inside the flaps, thereby improving the fit of the mask by conforming the mask to the contours of the nasal region, resulting in a mask with a nasal cushion that has cushioning properties and strong protective capabilities.</p> |
