Abstract

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.
