COVID-19: FIL assists media manufacturers to validate filter efficiency against global face mask requirements

September 2020

Filter Integrity Limited returned to the lab and office several months ago with COVID-19 security in place.

We have been heavily involved in the increased activity relating to face mask developments with a wide range of new researchers and manufacturers.

Palas GmbH  have supplied one of their newly developed PMFT 1000 M Protective Face Mask Systems allowing rapid analysis of face mask efficiency of full face masks and face mask media.

The equipment allows assessment of  filter efficiency from 145 nm up to 40 µm and enables testing to parameters defined in various national and international standards, including;

  • EN 143, EN 149, EN 13274-7
  • GB 2626 (‘KN’ grade)
  • 42CFR 84 (‘N’ grade)
  • ASTM 2299-3
  • CWA 17553
