3M 2128 dust filter P2 R

P2R filter: offers protection against harmless and harmful particulate matter (solid and liquid particles), ozone protection up to 10x NPF, organic vapors, and acid gases. Breathing is possible through both sides of the filter, which increases the surface area and reduces breathing resistance. These filters are suitable for masks of the 3M 6000 and 7000 series. Additional info: a minimum of 2 filters are required per half-face or full-face mask.
