A nasal air filtration device includes a pair of either planar or concave-convex filters, a support structure incorporating a pair of generally annular bases or sleeves for supporting the filters, and a bridge that couples the bases or sleeves to maintain them in a desired spaced-apart relation and to determine a desired angular relationship. The support structure is insertable into the nasal cavities to position the filters within corresponding nasal cavities. Flexible rims maintain the support structure and the filters in spaced-apart relation to the surrounding nasal wall. The filters may be placed within the bases at an angle with respect to the walls of the bases. Also, the filtration device may be flesh tone in color, thereby blending with the skin tone of the user. In some embodiments, a post structure is supplied for supplying a scent or aroma to the wearer.

1. A nasal air filtering device comprising: a first tubular body comprising an anterior end and a posterior end, and an inner wall of the first tubular body defining a first passageway therethrough, and further comprising a first rim disposed circumferentially about the first tubular body and extending radially outwardly therefrom;a second tubular body comprising an anterior end and a posterior end, and an inner wall of the second tubular body defining a second passageway therethrough, and further comprising a second rim disposed circumferentially about the second tubular body and extending radially outwardly therefrom;a first filtering medium extending from the inner wall of the first tubular body across the first passageway and a second filtering medium extending from the inner wall of the second tubular body across the second passageway; anda connecting member coupled to the first tubular body and the second tubular body;wherein the anterior end and posterior end of the first tubular body each define a plane and the anterior end and posterior end of the second tubular body each define a plane; andwherein the first filtering medium includes at least one generally flat surface that defines a plane which is nonparallel to the planes defined by the anterior end and posterior end of the first tubular body, and the second filtering medium includes at least one generally flat surface that defines a plane which is nonparallel to the planes defined by the anterior end and posterior end of the second tubular body. 2. The nasal air filtering device of claim 1, wherein at least a portion of the nasal filtering device comprises a flesh toned material. 3. The nasal air filtering device of claim 1, wherein the plane defined by the at least one generally flat surface of the first filtering medium and the plane defined by the at least one generally flat surface of the second filtering medium are non-parallel. 4. The nasal air filtering device of claim 3, wherein the first and second passageways, defined by the first and second tubular bodies respectively, have substantially elliptical profiles. 5. The nasal air filtering device of claim 1, wherein the entirety of the first and second filtering mediums are generally flat. 6. A nasal device, including: a first tubular body comprising an anterior end and a posterior end, and defining a first passageway therethrough, and further comprising a first rim disposed circumferentially about the first tubular body and extending radially outwardly therefrom;a second tubular body comprising an anterior end and a posterior end, and defining a second passageway therethrough, and further comprising a second rim disposed circumferentially about the second tubular body and extending radially outwardly therefrom; anda connecting member coupled to the first tubular body and the second tubular body;wherein in a cross-section taken in a plane parallel to at least one of the anterior and posterior ends of the first tubular body, the first passageway, defined by the first tubular body, has a cross-sectional shape which comprises substantially semi-circular ends and substantially linear sides connecting the ends, and wherein in a cross-section taken in a plane parallel to at least one of the anterior and posterior ends of the second tubular body, the second passageway, defined by the second tubular body, also has a cross-sectional shape which comprises substantially semi-circular ends and substantially linear sides connecting the ends. 7. The nasal device of claim 6, further comprising a first filtering medium and a second filtering medium disposed within the first tubular body and the second tubular body respectively. 8. The nasal device of claim 6, wherein at least a portion of the nasal device comprises a flesh toned material. 9. The nasal device of claim 8, wherein the connecting member comprises a flesh toned material. 10. The nasal device of claim 6, wherein one or more notches are disposed on the connecting member to provide one or more weakened points along the connecting member. 11. The nasal device of claim 6, wherein the connecting member comprises a biasing element. 12. The nasal device of claim 6, wherein the connecting member comprises a thinned portion along a length of the connecting member. 13. The nasal device of claim 6, wherein one or more written messages are provided on at least one of the first tubular body and second tubular body. 14. The nasal air filtering device of claim 1, wherein the connecting member comprises a thinned portion along a length of the connecting member. 15. The nasal air filtering device of claim 1, further comprising a first and second spring member at least partially annularly embedded in each of the first and second tubular bodies, respectively.
