Respirator Mask - KN95 Rated - (20 per Box)

KN95 rated mask provides at least 95% filter efficiency and protection from dust, gases, and airborne particles. Multi-layered mask has a barrier layer, two filtration layers, and a skin-friendly layer to make it more comfortable to wear. Ultra-fine electrostatic fabric and spunbonded non-woven cloth are used to form a quadruple filtration layer to more effectively filter harmful substances in accordance with international KN95 standards. Three-dimensional shape ensures tightness while also increasing the breathing volume of the mask. Flexible nosepiece adjusts to reduce voids and helps reduce inhalation of harmful substances.
