Does the 5log mask with Livinguard technology prevent Covid-19?

In scientific tests, textiles treated with Livinguard technology have been shown to neutralize SARS-CoV-2 viruses. This protection is maintained even after repeated wearing and washing when the mask is used as recommended.
However, the use of a 5log face mask is not a substitute for careful personal hygiene measures as recommended by the appropriate authorities. In addition, it cannot prevent infection if it is not worn or if the virus enters the respiratory tract by other means, such as cross-contamination via the person's hand.

Why does the 5log mask with Livinguard technology perform better than filtering masks?

Filtering masks can retain viruses. However, these are deposited on the surface of the mask, remain active there and can easily infect on contact.
In contrast, the 5log mask forms a protective shield against viruses and bacteria and destroys them on contact. Over 99.9% of all SARS-CoV-2 pathogens do not survive contact with the mask.
