Zentek Announces Test Results Validating ZenGUARD(TM) Enhanced Air Filters as a High-Performance Solution for ASHRAE Standard 241 Compliance
GUELPH, 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 Results ZenGUARD™ 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 241 Achieve this without an increase in pressure drop, energy consumption and carbon emissions Work with existing heating, ventilation, and air conditioning units Not require any additional equipment Extend filter life and reduce changeout frequency compared to more dense filters reducing labour and waste disposal costs ASHRAE Standard 241-2023: Control of Infectious Aerosols ASHRAE 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 to lower the risk of infection in indoor spaces. This is important because it gives schools, offices, and other public buildings a science-based way to improve indoor air quality and the health of building occupants. ASHRAE 241 focuses specifically on health and infection control, making it a key tool for creating safer indoor environments. The standard includes the use of MS2 bacteriophage as a standardized surrogate for evaluating the control of infectious aerosol. Its inclusion ensures a consistent benchmark for assessing the effectiveness of technologies such as ZenGUARD™ Enhanced Air Filters. Based on these new test results using MS2 bacteriophage, the Company now has science-based, directly comparable data demonstrating that ZenGUARD™ is highly effective at controlling infectious aerosols and is fully aligned with ASHRAE Standard 241 testing methodology. ZenGUARD™'s higher εPR translates to a higher ECA, making it a practical and effective option for inclusion in building readiness plans prepared by facility managers and building operators. Importantly, ASHRAE 241 assigns an εPR of zero to any filter rated below MERV 11A. However, ZenGUARD™, which has been independently tested with MS2, can be assigned an EPR of 42%, even when applied to a lower-rated MERV 9A filter. This allows facility managers to confidently adopt ZenGUARD™ technology without needing to upgrade to MERV 11A or higher filters, which may be incompatible with existing HVAC systems. 'These exciting new test results not only reinforce ZenGUARD™'s proven ability to improve indoor quality without increasing energy consumption - they highlight how our solution meets the requirements of ASHRAE 241, the most recent and relevant third-party guidance for controlling infectious aerosols in buildings,' said Greg Fenton, CEO of Zentek Ltd. 'Conventional panel filters - like electrostatically charged MERV 13s - are designed to trap dust and often fall short over time when it comes to impacting aerosols responsible for respiratory infections. In contrast, our filters were specifically designed to enhance mechanical filtration of infectious aerosol via the unique properties of our patented ZenGUARD™ technology - and we have now demonstrated our ability to do this in line with the only standard focused solely on infection control. As building operators face growing pressure to meet new air quality standards and carbon reduction targets, we're proud to offer our unique technology that is proven to effectively keep indoor spaces safe, while also reducing total cost of ownership and carbon emissions.'

Zentek Completes Shelf-Life Efficacy Testing for ZenGUARD(TM) Enhanced Air Filter Commercialization
GUELPH, ON / ACCESS Newswire / March 12, 2025 / Zentek Ltd. ('Zentek' or the 'Company') (NASDAQ:ZTEK)(TSXV:ZEN), an intellectual property technology development and commercialization company announces that shelf-life efficacy testing has been completed on aged ZenGUARD™ Enhanced Air Filters, which is required for medical device compliance. Highlights ZenGUARD™ Enhanced Air Filters were aged for 20 months prior to testing to establish the product's shelf life Viral filtration efficiency ('VFE') was unchanged after aging demonstrating that the ZenGUARD™ coating has a consistent performance over a duration of 20 months ZenGUARD™ Enhanced Air Filters On November 27, 2024, Zentek announced that the Company will manufacture and sell its ZenGUARD™ Enhanced Air Filters as a Class I medical device under its medical device establishment licence ('MDEL'). The change in regulatory pathway required the completion of 'End Product Stability and Performance Testing.' These tests are essential for medical devices as products must demonstrate consistent performance and safety of the device until a subsequent expiry date. The expiry date must be clearly identified on the label of all medical devices. ZenGUARD™ Enhanced Air Filters were real-time aged for 20 months and then submitted to LMS Technologies, Inc. ('LMS') for VFE and shedding testing. The VFE was tested for the aged filters to determine the reduction in bioaerosols that is achieved under normal operating conditions with an airflow of 500 ft/min and was consistent with ASHRAE 241 Section L standards. The recently completed testing of the 20-month aged filters measured an initial VFE of 38.1% which was similar to the original test performance of 37.7%. Likewise, a shedding test on the 20-month-aged filters was completed using a laser particle counter to determine the number and size of particles in the airstream under normal operating conditions (500 ft/min airflow). The shedding test demonstrated that the coating maintains excellent adhesion to the substrate over 20 months as the number of particles counted in the airstream after passing through the filter were within statistical deviation with the background particle counts measured with no filter present in the test chamber. Based on the VFE and shedding test results, ZenGUARD™ Enhanced Air Filters will be labelled with a 20-month expiry from the date of manufacture. The Company continues to prioritize the completion of all required documentation to support the manufacture and sale of ZenGUARD™ Enhanced Air Filters under its existing MDEL alongside ZenGUARD™ Surgical Masks. This documentation will be completed in compliance with Canadian Medical Device Regulations and ISO 13485:2016 Quality Management System for medical devices. Greg Fenton, Zentek's CEO, commented: 'The pathway to commercialization for ZenGUARD™ Enhanced Air Filters has been a long journey and we are pleased to have finally completed all testing necessary required for a medical device. These recent results further demonstrate to users that ZenGUARD™ Enhanced Air Filters are an effective and safe solution to help reduce the transmission of infectious bioaerosols up to the expiry date. We look forward to providing further announcements as we move towards commercialization.' About Zentek Ltd.

Zentek's Albany Graphite provides update on thermal purification results
Zentek (ZTEK)' Albany Graphite has received additional results from the fluidized bed reactor testwork. These results indicate that rare earth elements and other elements of interest can be recovered as a by-product of the thermal purification process. Highlights: Purification was performed utilizing an FBR directly on a ~950 g sample of the Albany flotation concentrate with no intermediate hydrometallurgical steps and yielded 99.9991% purity; Impurity elements, including REEs, removed from the flotation concentrate during the purification process were collected and concentrated in the scrubber that handles all the FBR exhaust products; Zentek will continue to investigate the REE potential of the Albany graphite deposit and tailings; The Company also plans on exploring both production and processing of graphite to create a battery-ready anode active material and a cathode conductivity enhancement material, as well as ultra-high purity graphite for nuclear applications. As reported in Zentek's January 8, press release, the Company had contracted a manufacturing company specializing in industrial graphite and carbon to explore the direct purification of Albany flotation concentrate using its proprietary continuous processing equipment. Zentek supplied a one-kilogram sample of the homogenized bulk flotation concentrate, which was characterized, aggregated into 3-D particles, and then run in an electrothermal FBR. As part of the characterization process, an elemental analysis was performed to identify the impurity elements. In its report, the manufacturing company noted that the feed material contained concentrations of REEs and other potential elements of value that could be recovered as part of the thermal purification process. Impurity elements, including the REEs, that were removed from the graphite during the purification process were collected and concentrated in a scrubber that handles all the FBR exhaust products.
