The cover body of this product is made of liquid silicone injection molding, with comfortable and durable silicone skirt design, which ensures good fitting and comfort of the facepiece and makes it more comfortable to wear for a long time.- The interface between filter piece and mask adopts standard thread(Rd 40x1/7) design, which is easy to install and disassemble. This product can enhance its protective ability by combining with the corresponding original filter. The lens of the product is a large-eye window perspective lens, providing a broad field of vision. At the same time, the lens is reinforced with anti-impact, anti-foggingging and other functions to provide users with more effective protection. Light weight, reduce the fatigue of the head and neck brought by the work. This product adopts standard 6-point high elastic head harness to reduce local pressure on the head and provide good comfort. The combination of the built-in efficient microphone and the exhalation valve is more conducive to sound transmission and improves sound transmission efficiency.
