The first or second rim portion has a shape configured for contacting and being latched on a perimeter of a user's nostril. The first or second crease portion is provided in the first or second rim portion, and the first or second crease portion comprises concentric ring-shaped creases and collapsed into a plane defined by the first or second rim portion when flattened and deployed into a conic or circular pyramid shape configured to fit in the user's nostril when pressed perpendicularly to the plane. The bridge portion connects the first rim portion to the second rim portion. The nasal filter is configured to be deployed into the user's nostrils and to provide a filtering of breathed-in air. ## Claims ### Claim 1 A nasal filter comprising: a first rim portion having a shape configured for contacting and being latched on a perimeter of a user's nostril; a first crease portion provided in the first rim portion, the first crease portion comprising a plurality of concentric ring-shaped creases in increasing diameter and collapsed flatly for storage into a first plane defined by the first rim portion and deployed into a conic or circular pyramid shape configured to fit in the user's nostril when pressed perpendicularly to the first plane; a second rim portion having a shape configured for contacting and being latched on a perimeter of the other nostril of the user; a second crease portion provided in the second rim portion, the second crease portion comprising a plurality of concentric ring-shaped creases in increasing diameter and collapsed flatly for storage into a first plane defined by the first rim portion and deployed into a conic or circular pyramid shape configured to fit in the user's nostril when pressed perpendicularly to the second plane; and a bridge portion connecting the first rim portion to the second rim portion, wherein the nasal filter is configured to be deployed into the user's nostrils and to provide a filtering of breathed-in air. ### Claim 2 (depends on 1) The nasal filter of claim 1, wherein the plurality of concentric ring-shaped creases of the first crease portion form a first wave pattern with same amplitude up and down from the first plane when stored and the plurality of concentric ring-shaped creases of the second crease portion form a second wave pattern with same amplitude up and down from the first plane when stored. ### Claim 3 (depends on 2) The nasal filter of claim 2, wherein the first wave pattern and the second wave pattern are the same. ### Claim 4 (depends on 2) The nasal filter of claim 2, wherein the first wave pattern and the second wave pattern are the different. ### Claim 5 (depends on 1) The nasal filter of claim 1, wherein each of the rim portions and the crease portions has a color coded for properties of the nasal filter including effectiveness, enhancement, and flavor. ### Claim 6 (depends on 1) The nasal filter of claim 1, wherein each of the first and second rim portions has substantially a shape of circle, ellipse, or rectangle. ### Claim 7 (depends on 1) The nasal filter of claim 1, wherein each of the first and second crease portions has at least four (4) concentric ring-shaped creases. ### Claim 8 (depends on 1) The nasal filter of claim 1, wherein the bridge portion comprises one or more creases for facilitating to adjust a width thereof. ### Claim 9 (depends on 2) The nasal filter of claim 2, further comprising: a first folding holder portion, located at an outer end of the first rim portion, comprising a plurality of creases configured for each crease bending selectively forming a horizontal part and a vertical part extending from the horizontal perpendicularly to securely fit the nose of the user, and configured for holding a perimeter of the user's nostril; and a second folding holder portion, located at an outer end of the second rim portion, comprising a plurality of creases configured for each crease bending selectively forming a horizontal part and a vertical part extending from the horizontal perpendicularly to securely fit the nose of the user, and configured for holding a perimeter of the other nostril of the user. ### Claim 10 (depends on 9) The nasal filter of claim 9, wherein each of the first and second folding holder portions is adapted to be flattened or bent and held in a specific shape. ### Claim 11 (depends on 9) The nasal filter of claim 9, wherein the first wave pattern and the second wave pattern are the same. ### Claim 12 (depends on 9) The nasal filter of claim 9, wherein the first wave pattern and the second wave pattern are the different. ### Claim 13 (depends on 1) The nasal filter of claim 1, further comprising a filter container made of a plate having a recess with a shape of the nasal filter adapted to receive the nasal filter. ### Claim 14 (depends on 13) The nasal filter of claim 13, further comprising a top sheet cover portion to be applied to and cover a top side of the filter container with the nasal filter received in the recess. ### Claim 15 (depends on 14) The nasal filter of claim 14, wherein the top sheet cover portion is detachable. ### Claim 16 (depends on 1) The nasal filter of claim 1, wherein the rim portions and the crease portions are made of filtering material such as filtering paper.
