Mr. Quinn, facility general manager, FSCC, commented: "I have been following graphene and its development journey for several years, and have expected that its unique properties and versatility would have the potential to enhance many indoor air quality solutions and building decarbonization initiatives. When we became aware that ZenGuard enhanced air filters were accomplishing this with graphene and silver without relying on more dense filters and increased energy consumption, we were immediately interested. At Dexterra, we are constantly searching for new innovations that can help us achieve our building efficiency goals -- and we look forward to adopting ZenGuard enhanced air filters across our facility and working with Zentek to share this real-world return on investment opportunity with many others across Canada. We also look forward to working with Zentek on developing other new graphene-enhanced indoor air quality solutions focused on reducing carbon emissions."
