Zentek Ltd. (“Zentek” or the “Company”) (Nasdaq: ZTEK; TSX-V:ZEN an intellectual property development and commercialization company, reports, further to its press release dated April 11, 2022, that it has received the final report from Phase 1 testing under its Innovation Solutions Canada (“ISC”) Testing Stream contract, which notes that all Phase 1 targets were met including: (i) a sufficient reduction in live airborne test organisms without modification to existing HVAC systems, (ii) no reduction in air flow rates, and (iii) no significant shedding of the ZenGUARD™ coating. ZenGUARD™-coated HVAC filters demonstrated a maximum improvement of 99% compared to equivalent MERV-rated uncoated filters using a bacteriophage (a SARS-COV-2 surrogate).

“The significant increase in filtration efficiency of pathogen-laden water droplets, without an impact to airflow rates, creates a potentially powerful solution in the HVAC space,” said Greg Fenton, CEO of Zentek. “Working with current systems, and not requiring additional energy or changes to existing equipment, our technology could be a simple and energy-efficient approach to providing cleaner air for indoor spaces and is highly supportive of current global indoor air quality initiatives.”


Phase 1 testing was conducted by CremCo Laboratories with assistance by the Aerospace Research Centre, a department of the National Research Council of Canada. Zentek is now in Phase 2 Testing at the National Research Council to demonstrate a reduction in live airborne surrogate contamination within a modular classroom environment, simulating a real-world environment. The Company will report results when completed and validated.
