new KN95 Face Masks 50 Pack 5-Ply Breathable Filter Disposable Face Masks Black About this item Mask Imported cloth Funight Ventilation Series KN95 Face Masks follow the GB2(contact info removed) respiratory protection standards. These standards require all masks to have a filtration efficiency of at least 95%, which means the material can filter out harmful molecules such as fine particles and dust. Ventilation Series KN95 Face Masks maintain a strict filtration efficiency standard while keeping the design comfortable and breathable. Each KN95 mask is composed of water column-grade melt-blown fabric, which has been proven to be more efficient than cloth masks due to its electrostatic properties. Through this design, Funight Ventilation Series KN95 Mask has achieved breathing resistance that is 20% better than that of the GB2(contact info removed) standard. Funight Black Face Mask: Increasing the width of the ear loop to 5.6 mm reduces pain in the ear and makes it more comfortable. And the ultrasonic welding technology we use makes the surfaces of two objects form a fusion between the molecular layers, without any rough stitches and thread ends, and make the ear hook stronger.
