Medline’s BioMask is the first and only FDA-approved anti-viral medical facemask. Employing cutting-edge technology, the BioMask utilizes the safe and natural ingredients of copper, zinc and citric acid to quickly and effectively inactivate 99.99% of influenza A and B viruses with 5 minutes. Conventional facemasks leave harmful viruses on the surface which can remain active and viable for days. This danger easily leads to cross-contamination and the spread of pathogens. BioMask™ is unique in that it protects beyond standard filtration masks to inactivate viruses on contact.
