**Overall Design:** Features a 3D three-dimensional foldable structure that contours to the human face, creating an independent breathing space that does not press directly against the mouth or nose, thereby significantly enhancing wearing comfort.

**Wearing System:** Equipped with widened, elastic head straps—distinct from standard ear-loop models—that ensure a secure fit without causing ear strain or slipping, even during prolonged use, making it suitable for full-day work requirements. The strap connection points feature reinforced stitching to ensure high tensile strength and resistance to breakage.

**Sealing Design:** An internal malleable aluminum nose strip is embedded at the bridge of the nose; this can be manually pressed to conform precisely to the curve of the nose, creating a perfect seal against facial gaps to prevent leakage and ensure effective protection.

**Craftsmanship:** The edges of the mask are finished using ultrasonic heat-sealing technology, resulting in clean seams free of adhesive residue or rough edges. The surface features a clearly printed N95 designation, indicating the protection level for easy identification.
