Abstract:
1. A nose filter adapted to be inserted into a nostril, the nose filter comprising: a housing having an external narrowing shape for allowing breathed air to pass through said housing, said housing comprising: at least one stationary filtering membrane disposed within said first lower cell, for filtering air; and at least one valve, for blocking exhaled air remaining in the second lower cell from flowing back into the upper cell when closed, and to allow exhaled air to flow out from the upper cell into the second lower cell when open, wherein said at least one valve is operative to block said second air passageway upon inhalation, and operative to open said second passageway upon exhalation, and wherein said at least one valve comprises a flexible cover attached to the lower side of said second air passageway, and wherein said second stationary lower cell and said upper cell are empty of a filtering membrane, and wherein said housing is formed from a flexible material, and a substantial portion of the upper cell is directly above and vertically aligned with said first and second lower cells, and a center wall separating the first and second lower cells is vertically aligned with said upper cavity, thereby said stationary upper cell disposed above said first and second lower cells and comprising a portion of a length of said housing, is conformable; and thereby said at least one valve blocks exhaled air, being left within said second lower cell, from returning into the nostril upon inhaling, and thereby the disposition of said at least one valve within said housing provides space for disposing a flange outside said housing, for connecting said nose filter to another nose filter.
