Abstract:
An air filtering device for nasal breathing. The device comprises: a first filter (1) and a second filter (2) that are suitable for wearing inside a user nasal cavity; and a connector (3) connecting the first filter (1) and the second filter (2). Each of the first filter (1) and the second filter (2) comprises a supporting member (11) and a filtering member (8). The supporting member (11) and the filtering member (8) are integrally formed by insert molding and constitute a non-detachable whole. The supporting member (11) comprises a supporting part (5) that is used to support the filtering member (8) and a fitting part (4) that is integrally extended from the supporting part (5) and that fits the user nasal cavity. The supporting member (11) and the filtering member (8) are integrally formed, simplifying the part assembly process, reducing costs, and avoiding contamination of the air filtering device for nasal breathing in the assembly process, thereby providing a clean, hygienic air filtering device for nasal breathing.
