3M 2125 P2R Particle Filter for Solid and Liquid Particles

Standards and labels

• EN 143:2021

  EN 143:2021 is a European standard for particle filter respirator mask. It defines the minimum requirements for filter efficiency, filter penetration, and breathing resistance, as well as the test methods used to determine compliance with these requirements. The standard also specifies the types of particle filters that can be used in respirator masks and the information that must be provided by manufacturers. Possible test results include filter efficiency, filter penetration, breathing resistance, which must meet the minimum standards set by the standard.

  Test results

  P2

  The P2 result in the EN 143:2021 standard signifies a moderate level of filtration efficiency for particulate filters used in respiratory protective devices. Specifically, it indicates that the filter filters at least 94% of airborne partilces. This criterion is central for ensuring that masks provide adequate protection against environments with particulate pollutants. The testing method involves passing an aerosol of sodium chloride or paraffin oil through the filter material and measuring the concentration of particles in the air before and after it passes through the filter. The test assesses the filter's ability to reduce particulate ingress, reflected in a percentage efficiency. A P2 classification means the filter captures a significant amount of harmful particles, making it suitable for environments with moderate levels of fine particles, such as those found in some industrial settings. This result is particularly relevant for stakeholders in industries where respiratory health and safety are priorities, guiding them in selecting appropriate protective equipment to comply with occupational health regulations.

• CE Marking

  CE Marking is a label that shows a product meets certain safety and environmental standards set by the European Union. To get the CE Marking, a company must test and certify their product meets these standards. CE Marking is required for many products sold in the EU, including electronics, machinery, toys and medical devices. It helps ensure that products are safe for consumers and the environment, and allows for easy trade within the EU.
