How ZenGUARD™ Surgical Masks Work

ZenGUARD™ Surgical Masks utilize the patented ZenGUARD™ technology as a key filtration enhancement. This revolutionary graphene compound allows it to better filter harmful pathogens. The result?

A standard surgical mask* utilizing a single layer of ZenGUARD™ technology removes 98.9% more bacteria and 97.8% more viruses compared to an identical surgical mask without the ZenGUARD™ layer.
