This has been one of the most frequent questions received since early 2020 and now, we can officially say, yes! All members of our breathing filter family are now SARS-CoV-2 validated for Europe under CE mark!*
As the world continues to battle the SARS pandemic, which has claimed the lives of more than 3 million people and infected more than 150 million, the issue of contamination containment has continued to be a major source of concern. To mitigate these issues, we have upgraded our breathing portfolio to be highly efficient in retaining the SARS-CoV-2.
We have subjected a substantial number of our Ultipor™ 25, Ultipor™ 100, and BB50TE filters to vigorous testing with the actual SARS-CoV-2 (Fig 1). Every filter was challenged with > 100 million heat-inactivated SARS-CoV-2 viruses.
Figure 1. Testing set-up.
We can confirm that all filters consistently retain more than 99.999% of the aerosolized virus.
This result is also in alignment with our earlier work, which demonstrated > 99.999% retention of other airborne human pathogenic viruses and bacteria. Our breathing system filters contain a highly efficient hydrophobic filter medium and also showed 100% retention of liquid-borne human pathogenic viruses like HIV and Hepatitis C.
We are happy to provide this additional piece of evidence to our customers in support of choosing the best product for the protection of patients, staff, and equipment.
