Jon Bhandari D-032 - Dust Mask - It is a half-mask type. It comes with a self-closing valve. It is light in weight with a soft grey colour. It has an anti-pollution exhalation valve and nose clip for a sealed nose and mouth area. It is suitable for construction as air-supplied respirators. The outermost layer filters out the largest dust particles. While the innermost layer preserves the respirator S shape, and the middle layer is composed of electrostatic filter media. The blue portion of the mask is a protective shield to don't let the mask get dirty easily outdoors. The cool flow valve makes it comfortable when used for a longer time and in hot weather conditions.
