NASAL FILTER

摘要

A nasal filter comprising two cap-shaped structures and a connecting strip. Two extremities of the connecting strip respectively are connected symmetrically to either of the cap-shaped structures. The nasal filter also comprises filter components. The filter components respectively are mounted at the bottom parts of the two cap-shaped structures. Several protrusions are provided on the inner walls of the cap-shaped structures. The bottom parts of the cap-shaped structures are constituted by several cap-shaped structure horizontal beams. The bottom parts and the protrusions jointly jam the filter components. The nasal filter is capable of preventing a filter material from being ejected to the exterior of the cap-shaped structures by air exhaled from the nasal cavities, allows for replacement of the filter material, thus improving the adaptability and economy of the nasal filter in different scenarios.
