Such fasteners are configured to maintain the scented air filter away from the nostrils of the user while the bottom portion is pivoted to a raised position relative to the top portion. Each of the arcuate anterior section and the arcuate posterior section has a nose-shaped profile. The arcuate posterior section includes a deformable body selectively morphed to the nose-shaped profile and is configured to cover a major surface area of a user nose, and maintain a friction engagement with the user nose as well as the arcuate posterior section. ## Claims ### Claim 1 A nostril-shielding nasal mask for filtering ambient air prior to entering nostrils of the user, said nostril-shielding nasal mask comprising: an adjustable body configured to cover a nose bridge and nostrils of a user, said adjustable body including a top portion having a concave shape and being provided with an arcuate anterior section and arcuate posterior section opposed therefrom; a hinge attached to said top portion; a bottom portion attached to said hinge, said bottom portion having a planar shape and being provided with a curvilinear anterior face and a rectilinear posterior face, said bottom portion further having a plurality of apertures configured to align with the nostrils of the user, respectively; a scented air filter removably inserted through said rectilinear posterior face and into said bottom portion, said scented air filter being spaced from said top portion; and a plurality of fasteners attached to said top portion and said bottom portion, said fasteners being configured to maintain said top portion and said bottom portion directly abutted against the nose bridge of the user and the nostrils of the user, respectively; wherein each of said arcuate anterior section and said arcuate posterior section has a substantially nose-shaped profile. ### Claim 2 (depends on 1) The nostril-shielding nasal mask of claim 1, wherein said arcuate posterior section is coextensively shaped as said arcuate anterior section and is frictionally fitted directly against an arcuate posterior side of said arcuate anterior section. ### Claim 3 (depends on 1) The nostril-shielding nasal mask of claim 1, wherein each of said arcuate posterior section and said arcuate anterior section are configured to remain above nostril openings of the user. ### Claim 4 (depends on 3) The nostril-shielding nasal mask of claim 3, wherein said top portion is configured to remain statically abutted directly against the nose bridge of the user while said bottom portion is articulated along said common arcuate path between a second raised, non-operating position and a second lowered, operating position. ### Claim 5 (depends on 1) The nostril-shielding nasal mask of claim 1, wherein said hinge is extended downwardly and away from said arcuate anterior section and terminates anterior of said arcuate anterior section such that a fulcrum axis of said hinge is disposed below said apertures. ### Claim 6 (depends on 1) The nostril-shielding nasal mask of claim 1, the arcuate anterior section is configured to receive and support an existing eyeglasses frame thereon. ### Claim 7 (depends on 1) The nostril-shielding nasal mask of claim 1, wherein each of said top portion and said bottom portion is configured to selectively articulated along a common arcuate path defined about a fulcrum axis of said hinge. ### Claim 8 (depends on 1) The nostril-shielding nasal mask of claim 1, wherein said arcuate anterior section and said arcuate posterior section are solid and continuously extend between a top edge and a bottom edge of said top portion. ### Claim 9 (depends on 1) The nostril-shielding nasal mask of claim 1, wherein said plurality of fasteners comprise: a first finger statically attached to said arcuate anterior section and protruding outwardly away therefrom; and a notch disposed at said bottom portion and being configured to receive said first finger when said top portion is articulated to said first lowered, non-operating position; wherein said first finger is frictionally and detachably engaged with said scented air filter when said first finger is interlocked in said notch, said first finger being configured to maintain said scented air filter at said top portion when said bottom portion is articulated upwardly to a second raised, non-operating position and while said top portion is at a first raised, operating position. ### Claim 10 (depends on 9) The nostril-shielding nasal mask of claim 9, wherein said plurality of fasteners further comprise: a second finger and a third finger spaced therefrom, each of said second finger and said third finger being affixed to said top portion; a second notch and a third notch disposed at said curvilinear anterior face of said bottom portion; wherein said second finger and said third finger are directly interlocked with said second notch and said third notch, respectively, when said top portion is disposed at a first raised, operating position and said bottom portion is disposed at a second lowered, operating position. ### Claim 11 (depends on 1) The nostril-shielding nasal mask of claim 1, wherein said apertures are equidistantly offset from a centrally registered latitudinal axis and configured to align beneath a respective one of the nostrils of the user, respectively. ### Claim 12 A nostril-shielding nasal mask for filtering ambient air prior to entering nostrils of the user, said nostril-shielding nasal mask comprising: an adjustable body configured to cover a nose bridge and nostrils of a user, said adjustable body including a top portion having an arcuate anterior section and arcuate posterior section opposed therefrom; a hinge attached to said top portion; a bottom portion attached to said hinge; a scented air filter removably inserted through said bottom portion; and a plurality of fasteners attached to said top portion and said bottom portion, said fasteners further being configured to maintain said scented air filter away from the nostrils of the user while said bottom portion is pivoted to a raised position relative to said top portion; wherein each of said arcuate anterior section and said arcuate posterior section has a nose-shaped profile; wherein said arcuate posterior section includes a deformable, continuous, and smooth rubber body selectively morphed to the nose-shaped profile and being configured to cover a major surface area of a user nose; wherein said deformable, continuous, and smooth rubber body is pliable and provided with a tacky outer surface configured to simultaneously maintain a friction engagement with the user nose as well as said arcuate posterior section. ### Claim 13 (depends on 12) The nostril-shielding nasal mask of claim 12, wherein said bottom portion has a planar shape and is provided with a curvilinear anterior face and a rectilinear posterior face, said bottom portion further having a plurality of apertures configured to align with the nostrils of the user, respectively. ### Claim 14 (depends on 12) The nostril-shielding nasal mask of claim 12, wherein said scented air filter is removably inserted through said rectilinear posterior face and into said bottom portion, said scented air filter being spaced from said top portion. ### Claim 15 (depends on 12) The nostril-shielding nasal mask of claim 12, wherein said fasteners are further configured to maintain said top portion and said bottom portion directly abutted against the nose bridge of the user and the nostrils of the user, respectively. ### Claim 16 (depends on 12) The nostril-shielding nasal mask of claim 12, the arcuate anterior section is configured to receive and support an existing eyeglasses frame thereon.
