Low-dust activated carbon mask, overhead (4-ply type), 50 pieces, 1 box (50 pieces)

The surface material is made of ES fiber (PP/PE composite fiber), so it feels smooth to the touch and has almost no fraying or falling out fibers. It has a four-layer structure that includes an activated carbon filter with high deodorizing properties, making it effective for working in environments where odors are a concern. The four-layer structure provides high dust collection efficiency and excellent dust resistance. The masks are individually wrapped for hygiene.
