Abstract

Disclosed is an embedded nasal filtering apparatus, comprising a support body, an air permeable sac and a filtering element. The support body comprises a frame portion corresponding to the position of a nostril, and the frame portion defines a telescoping direction. The air permeable sac is connected to the frame portion, and the air permeable sac can be adjusted from a folded state to an unfolded state along the telescoping direction. When in the unfolded state, the air permeable sac forms an opening and an accommodating space which are mutually connected. The position of the filtering element corresponds to the frame portion. By means of the described design, the present invention can adapt to users having different intranasal space sizes.
