Respirator Mask - Multi-layered mask has a barrier layer, two filtration layers, and a skin-friendly layer to make it more comfortable to wear. This KN95 Rated mask provides at least 95% filter efficiency and protection from dust, gases, and airborne particles. 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. Each mask is individually packaged in a resealable poly envelope.
