Lydall President & CEO Sara Greenstein commends Biden Administration and ASTM International for new face covering standards

ASTM International has introduced new certification standards for General Barrier Face Coverings, giving the general public greater awareness and control over the level of protection provided by cloth face masks. ASTM Level 1 Face Coverings block at least 20% of particles 0.3 micron and larger (including bacteria and many viruses), while ASTM Level 2 Face Coverings block at least 50% of these particles.

Lydall Urges Consumers to Buy ASTM-Certified and Buy American-Made

In response to these new standards, Sara Greenstein, President & CEO of Lydall, Inc., provided the following statement:

“Lydall and our team of filtration and materials science experts were honored to work alongside ASTM International, the CDC, INDA and our fellow industry colleagues in this joint effort to better educate consumers about the level of protection face masks provide against threats like COVID-19. Since the onset of the pandemic, manufacturers all over the world have stepped up to accelerate production of personal protective equipment and the materials they require, but demand still heavily outweighs supply.

For that reason, it remains critically important that we right-size our face masks for our level of risk – and in order to do that, we must understand exactly how much protection masks offer. N95 respirators and surgical masks that contain fine fiber meltblown filtration media remain the gold standard, but these new standards provide much-needed guidance for a broader range of more widely available masks. The message is clear: by buying ASTM-certified and buying American-made, consumers can have clarity and confidence in the level of defense their masks deliver against the virus.”
