The 9310 dust masks are designed based on the advanced three-panel design of the 3M 9300 series, which practically means they make breathing more comfortable without collapsing onto the face. They can also be folded, making them more convenient than conventional cup-shaped masks. Their construction advantages include the material of their straps, which ensures a good and stable fit on the face without the excessive pressure of conventional support materials. Even greater comfort is achieved with the use of a soft material for the parts of the mask that come into contact with the skin.
