Inside the mask

Four layers. One enhanced.

ZenGUARD™ is a graphene-based coating, not a mask. We start with a standard ASTM Level 3 surgical mask and coat one of its layers right on the fibres, so the layers you already trust work harder.

A standard four-layer surgical mask. Every layer untreated.
