3M 7503 (size: L) filtering half mask with two protective filters - 3M 7503
3M 7503 protective half mask, large size. Gas and steam masks with particulate filters. The 3M long life 7500 series half masks have been designed for very harsh working environments. 3M's innovative protective half masks are made of eudermic silicone and feature unique trigger bands. The wristbands allow the wearer to remove the mask during short breaks without having to remove it completely. In addition, they effectively prevent the accumulation of heat and moisture in the face part, making it even more comfortable and safe. The double-filter design on the sides reduces breathing resistance, provides a more balanced fit than masks with a single heavy filter on the front, and improves field of vision.
