Zentek wins Government of Canada standing offer for graphene-enhanced HVAC filters

ZenGUARD filters use Zentek’s patented graphene technology and are manufactured in Canada as drop-in replacements for standard HVAC filters. The company reports approximately a fivefold improvement in aerosol filtration efficiency over untreated filters, without an increase in pressure drop or energy consumption. In a real-world pilot at McKinnon Park Secondary School, ZenGUARD filters reportedly delivered 22% lower fan energy use compared with standard MERV 13 pleated filters, alongside substantially longer projected service intervals. The technology has also been independently validated by the National Research Council of Canada.
