[{"type":"text","content":"Zentek Announces Breakthrough Results in Viral Filtration Efficiency with Dust LoadingGUELPH, ON / ACCESSWIRE / September 6, 2023 / Zentek Ltd. (\"Zentek\" or the \"Company\") (NASDAQ:ZTEK)(TSXV:ZEN), an intellectual property technology development and commercialization company is pleased to announce the results of a recent study comparing the Viral Filtration Efficiency (\"VFE\") of its ZenGUARD™-enhanced MERV 9 filters with an uncoated MERV 9 filter. The testing was performed by the third-party lab LMS Technologies Inc. (\"LMS\"), which specializes in the testing and certification of filter manufacturers across the world, referring to the new American Society of Heating, Refrigerating and Air-Conditioning Engineers (\"ASHRAE\") standards for aerosolized particles and determining the impact of dust loading on VFE and particle filtration efficiency (PFE) as per ASHRAE 52.2 testing standards.Key Findings:Increased Viral Filtration Efficiency with Dust Loading: The VFE of ZenGUARD™-enhanced filters started with a significant advantage over equivalent non-coated filters, from 23.7% to 37.7%, a 59% enhancement or a 14% net gain overall. After the initial test, the VFE was remeasured after dust was added to the filters that was equivalent to 1, 2, 3 and 6 months of operation. At every dust loading, the VFE performance consistently increased faster for the ZenGUARD™-enhanced filters compared to the uncoated filters. At six months equivalent dust loading, the VFE of the ZenGUARD™-enhanced filter was 85.6% compared to 55.2% for the uncoated filter, a 28.4% net gain. The viral particles were suspended in 0.1um aerosols or smaller, equivalent to the lower range of E1 particles (<1.0um). Testing using this size of aerosol is significantly more rigorous than the testing methodology accepted in the new ASHRAE standard for control of infectious aerosols. These parameters and rationale are consistent with the testing that was performed for the Phase 2 Innovative Solutions Canada Challenge conducted by the National Research Council of Canada in the simulated classroom environment.Consistent Pressure Drop: The pressure drop remained consistent between ZenGUARD™-enhanced and uncoated filters as dust loading increased, indicating that ZenGUARD™ does not adversely affect airflow or energy efficiency of t...
