ZenGUARD™ is Zentek’s patented technology platform. Utilizing the revolutionary benefits of the carbon-based nanomaterial graphene, ZenGUARD™ is a technology that can be easily applied to materials to enhance their viral filtration efficiency.
ZenGUARD™ transforms simple, critical items such as surgical masks and other products into high‑performance protective tools without changing how people use them.
How ZenGUARD™ Works
ZenGUARD uses the unique properties of graphene‑based nanomaterials and a hydrophilic, water‑attracting surface to disrupt pathogen‑carrying aerosols.
- The coating attracts and captures tiny airborne droplets and particles that can carry viruses and bacteria.
- The graphene-silver combination delivers strong disruption properties.
- The coating is applied as a thin, uniform layer so products like surgical masks maintain breathability and comfort.
This combination allows ZenGUARD™-treated materials to significantly improve filtration and infection-control performance compared with uncoated equivalents.
ZenGUARD™ Surgical Masks
ZenGUARD Surgical Masks use the same familiar mask form factor with an added ZenGUARD™ coating on the outer layer.
- Four‑layer, ASTM Level 3 masks with high bacterial, viral and particle filtration efficiency.
- ZenGUARD™ coating provides a further boost in antimicrobial performance versus standard Level 3 masks.
- Designed for healthcare and other high‑risk environments where enhanced protection is important.
Users wear ZenGUARD™ masks like any other surgical mask, while benefiting from the added protection of the coating.
