Abstract

Device (10) for filtering the air inhaled through the nasal openings and capturing dust, extraneous materials, bacteria, pollen and like particles which can cause damages to the respiratory organs of the user. The filtering device (10) is characterized in that it comprises filter-supporting elements (11) which have a substantially annular shape and are made of material which is sufficiently elastic to conform to the inner surface of the nasal cavities (C). A filtering element (20), which has one or more layers spaced from each other, can be removably inserted in the opening defined by the annular element (11). An elastic retaining element (30) is adapted to engage a portion of the nose for retaining the filtering device (10) in its correct working position.
