In December 2022, C&M developed a new composite filter media which can be used in respiratory protective devices(particle filters).

Compared to the glass fiber material which is commonly used in respiratory protective devices (particle filters), the new composite material is easy to process and transport without damage. The breathing resistance of the filter can be reduced by 40%-60%. The service life is longer in the same using environment. This new composite material can achieve KP100/P100/FFP3 filtration level.
