3M 2138 P2–P3 particle filter providing high-efficiency protection against dusts, fumes and airborne particulates.

High-efficiency particulate filter for compatible 3M respirators

High-efficiency particulate filter designed for reliable respiratory protection in demanding environments.

The 3M Particle Filter 2138 P2–P3 is a professional-grade respiratory protection component engineered to provide high-level filtration against hazardous airborne particulates. Designed for use with compatible 3M reusable half face and full face respirators, the 2138 filter delivers P2–P3 level protection against fine dusts, mists and fumes when used correctly. The compact, low-profile design helps maintain balance and comfort while reducing breathing resistance during extended wear. Key benefits include high filtration efficiency, dependable performance and compatibility with a wide range of 3M respirator systems. Compared to lower-rated particulate filters, the 2138 offers enhanced protection for more demanding applications. It is widely used in welding, metal fabrication, construction, manufacturing, maintenance and industrial environments where effective particulate respiratory protection is essential.
