Our KF94 face respirators are designed to limit unfiltered air entry and securely fit your face. Its 3D design is tight-fitting and protective with ease of breathability and communication. The side flaps stay flushed against your face and reduces the risk of the wearer readjusting their face mask. This provides a secure seal and double protection from all sides of the face mask. The face mask is made of double layered melt-blown filter fabric with ≥98% BFE (Bacterial Filtration Efficiency) and ≥98% PFE (Particle Filtration Efficiency) which works to block out bacteria, pollution, pollen and dust particles from your surroundings. Available in a box of 16s (not individually packed).
