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.

Flexible rims maintain the support structure and the filters in spaced-apart relation to the surrounding nasal wall. The rims conform to surrounding nasal tissue to form seals. The rims can be selectively inclined to facilitate insertion and resist accidental removal. In certain embodiments the device is combined with a filter that covers the mouth to provide an air filtration system.

Abstract: A nasal air filtration device includes a pair of concave-convex filters, and a support structure incorporating a pair of generally annular bases for supporting the filters, and a bridge that couples the bases, to maintain them in a desired spaced-apart relation and to determine a desired angular relationship between the bases and between the associated filters. The support structure is positionable against the anterior nares to direct the filters into their corresponding nasal cavities. The support structure maintains each of the filters in spaced-apart relation to the surrounding nasal wall. In alternative embodiments, an open frame is mounted to each base and positioned between its associated filter and the nasal wall.
