- Zentek’s commitment to air quality and sustainability positions it as a leader in the air filtration technology market.

Zentek Ltd. Advances Air Quality Solutions with ZenGUARD Enhanced Filters
Zentek Ltd., a technology development company based in Guelph, showcases significant progress in air quality management with the recent test results of its ZenGUARD Enhanced Air Filters. The filters demonstrate a remarkable average infectious aerosol removal efficiency (ePR) of 42% against the bacteriophage MS2, as confirmed by independent testing from LMS Technologies Inc. This performance is particularly noteworthy given that untreated filters yield a mere 16% efficiency. Such findings underscore ZenGUARD’s alignment with the ASHRAE Standard 241, which sets forth guidelines aimed at reducing airborne virus transmission in buildings, making it a vital solution in today's health-conscious environment.
The ZenGUARD filters not only meet but exceed industry standards without incurring increased energy consumption, pressure drop, or carbon emissions. This efficiency allows existing HVAC systems to integrate the filters seamlessly, negating the need for costly equipment upgrades. By providing a higher Equivalent Clean Airflow (ECA), ZenGUARD filters present a compelling alternative for facility managers seeking to improve indoor air quality without resorting to more expensive solutions, such as MERV 11A filters. Greg Fenton, CEO of Zentek, emphasizes that conventional filters typically struggle with aerosol filtration, whereas ZenGUARD is engineered specifically to target and mitigate this issue effectively.
Zentek's commitment to enhancing indoor air quality while simultaneously addressing operational costs and environmental impact positions the company as a leader in the air filtration market. With ongoing concerns surrounding airborne pathogens, the introduction of ZenGUARD filters may not only offer a practical solution for businesses and facilities but also contribute to broader public health initiatives by reducing the risk of indoor transmission of infectious diseases. The integration of ZenGUARD technology into existing infrastructure marks a significant step forward in ensuring cleaner, safer indoor environments.
In addition to the promising test results, Zentek's innovative approach aligns with growing demands for sustainable and effective air quality solutions. The company’s focus on research and development positions it well within the competitive landscape of air filtration technology. As the market continues to evolve, Zentek's advancements in filtration solutions are poised to play a crucial role in the ongoing efforts to combat airborne viruses and enhance overall public health standards.
Overall, Zentek Ltd. not only enhances air quality with its innovative ZenGUARD filters but also underscores its dedication to sustainability and operational efficiency, making it a noteworthy player in the air purification industry.
