The 3D disposable protective mask is made of high-quality cotton and non-woven meltblown filter cloth. The three-layer filter system effectively prevents a series of airborne pollutants. 3D fits your face better and is better for breathing. 3D dust masks filter out 95% of exhaust gas, dust, chemicals, particles, pollen, smoke and fumes. Lifting ear design and removable hook-and-loop strap help to effectively seal and prevent fogging, making the mask non-slip.
