Problems solved by technology

However, because polyurethane foam and other sponges are used, cheap raw materials have air permeability, so there are disadvantages such as high possibility of dust passing through the cross section of the sponge and invading into the mask, and high humidity exhalation passing through the sponge and blurring the glasses.
In addition, independent foam materials without air permeability are expensive
[0007] In addition, although there is also a method of turning back the vicinity of the nose of the filter to the side close to the face to improve the adhesion (patent document 3) and a method of attaching other filters to the back side of the mask ( Patent Documents 4 and 5), but the resiliency to ensure sufficient adhesion cannot be obtained

Abstract

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 cushion with a nasal cushion that has cushioning properties and strong protective capabilities.
