Cutting-Edge Nanotechnology Defence

Transforming Simple Items Into Critical Protective Tools

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.

This boost in protective efficiency has been demonstrated with ZenGUARD™ Surgical Masks which are used in the same way as similar surgical mask products. Zentek aims to do the same with HVAC air filters.


Imagine healthier, cleaner workplaces and healthcare facilities using products virtually identical to those already in use today.

What is ZenGUARD™?

ZenGUARD™ isn’t a future dream. It’s a material ready to make a difference right here, right now. The product of two years of research and testing, ZenGUARD™ leverages graphene to surpass the filtration performance of legacy materials.
