GUELPH, ON / ACCESSWIRE / September 27, 2021 / ZEN Graphene Solutions Ltd. ("ZEN" or the "Company") (TSXV:ZEN)(OTC PINK:ZENYF), a Canadian, nanotechnology company focused on next-gen healthcare solutions, announces test results demonstrating significantly enhanced bacterial filtration efficiency (BFE) and viral filtration efficiency (VFE) of ZENGuard™-enhanced surgical masks. The ZENGuard™ coated masks removed 98.9% more bacteria and 97.8% more virus particles compared to a typical ASTM level 3, 3-ply uncoated mask. With BFE and VFE levels over 99.99%, the company believes that these are the highest filtration efficiency numbers for surgical masks in the market.

"Our patent-pending ZENGuard™ compound continues to surprise us by exhibiting additional beneficial properties when applied to surgical masks. Our goal is to provide front-line workers and those in higher risk environments with the best protection available - and our ZENGuard™ technology achieves this not only by its antimicrobial properties, but also by substantially reducing the number of viable bacteria and virus particles that are able to pass through the mask material. We believe these properties are key differentiators for surgical masks and will make this product the gold standard in the market. We look forward to bringing this technology to other types of PPE as well and ultimately getting this additional protection to those that need it most." commented Greg Fenton, ZEN CEO.

"With compelling safety and efficacy data, regulatory approval, and existing demand requirements growing rapidly, we are acutely focused on scaling up our production capacity from a coated-mask equivalent of over 30 million per month, to industrial capacity of approximately 800 million per month, which we remain on target to achieve by the end of 2021." Mr. Fenton added.

Bacterial and Viral Efficiency Testing

  • Testing was completed by GAP EnviroMicrobial Services Ltd., an ISO/IEC 17025:2005 compliant and Canadian Association for Laboratory Accreditation (CALA) certified testing facility
  • A ZENGuard™-enhanced mask and a leading ASTM level 3, 3-ply mask were exposed to S. aureus for BFE testing and MS2 Bacteriophage for VFE testing
  • ZENGuard™-enhanced mask removed 98.9% more bacteria and 97.8% more viruses in a head-to-head comparison with a leading ASTM level 3 mask
