Zentek announces independent test results on ZenGUARD Enhanced Air Filters

Zentek (ZTEK) announced new independent test results comparing the viral filtration efficiency of ZenGUARD Enhanced Air Filters against the bacteriophage MS2 compared to equivalent Minimum Efficiency Reporting Value-rated filters without ZenGUARD. The testing was performed by the third-party ISO 17025:2017 certified lab LMS Technologies, 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 standards. ZenGUARD Enhanced Air Filters achieved an average infectious aerosol removal efficiency of MS2 bacteriophage of 42% compared to an untreated filter, which achieved an average PR 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.
