[{"type":"text","content":"Zentek Announces Test Results Validating ZenGUARD(TM) Enhanced Air Filters as a High-Performance Solution for ASHRAE Standard 241 ComplianceGUELPH, ON / ACCESS Newswire / June 12, 2025 / Zentek Ltd. (\"Zentek\" or the \"Company\") (Nasdaq:ZTEK)(TSXV:ZEN), an intellectual property technology development and commercialization company, is pleased to announce new independent test results comparing the viral filtration efficiency (\"VFE\") of ZenGUARD™ Enhanced Air Filters against the bacteriophage MS2 compared to equivalent Minimum Efficiency Reporting Value (\"MERV\")-rated filters without ZenGUARD™. The testing was performed by the third-party ISO 17025:2017 certified lab LMS Technologies Inc. (\"LMS\"), which specializes in the testing and certification of filter manufacturers across the world in line with American Society of Heating, Refrigerating and Air-Conditioning Engineers (\"ASHRAE\") standards.Test ResultsZenGUARD™ Enhanced Air Filters achieved an average infectious aerosol removal efficiency (εPR) of MS2 bacteriophage of 42% compared to an untreated filter, which achieved an average εPR of 16%. These strong results align with previous tests performed with bacteriophage Phi6, which is often used as a surrogate for SARS-CoV-2 and other enveloped viruses.This milestone adds to a growing body of third-party validation demonstrating ZenGUARD™ Enhanced Air Filter's unique combination of effectiveness and simplicity. To highlight this, the Company believes ZenGUARD™ Enhanced Air Filters are the only technology that can accomplish the following simultaneously:Highly effective at controlling infectious aerosol in line with ASHRAE 241Achieve this without an increase in pressure drop, energy consumption and carbon emissionsWork with existing heating, ventilation, and air conditioning unitsNot require any additional equipmentExtend filter life and reduce changeout frequency compared to more dense filters reducing labour and waste disposal costsASHRAE Standard 241-2023: Control of Infectious AerosolsASHRAE Standard 241 is new guidance designed to help buildings reduce the spread of airborne viruses, like SARS-CoV-2, influenza, and other respiratory illnesses. It sets clear guidelines for Equivalent Clean Airflow (\"ECA\") (from ventilation, filtration, or air cleaning) that is needed t...
