This 5-ply KN95 protective respirator face mask is engineered with dual electrostatically charged meltblown filtration layers sandwiched between skin-friendly spunbond non-woven fabric and a structural hot-air cotton support layer. It achieves >= 95% particle filtration efficiency (PFE) against non-oily aerosols, fine droplet nuclei, bacteria, and dust down to 0.3 microns. Its 3D ergonomic folding design creates a spacious internal breathing chamber that prevents lip contact, complemented by an adjustable concealed aluminum nose bridge and soft elastic earloops.
Beyond the core description above, KN95 Facemask is commonly specified for Hospital Respiratory Triage and Aerosol-Generating Procedures, Outpatient Clinical Consultation and Infection Prevention, Biomedical Laboratory and Pathological Research Suites.
