ZenGUARD™ Surgical Masks

Cutting-Edge Pathogen Protection

ZenGUARD™ Surgical Masks leverage next-generation materials to deliver incredible levels of pathogen filtration, protecting people from exposure to airborne viruses and bacteria like never before.

This ground-breaking technology is highly effective, affordable, and ready to implement right now – using a standard surgical mask design familiar to healthcare workers around the world.

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.
