GUELPH, ON / ACCESS Newswire / March 4, 2026 / Zentek Ltd. ("Zentek" or the "Company") (TSXV:ZEN)(NASDAQ:ZTEK) is pleased to announce the initiation of a pilot evaluation program with Quality Filters Inc. ("Quality"), a U.S.-based manufacturer of heating, ventilation and air conditioning ("HVAC") and industrial air filtration products, to assess the integration of Zentek's proprietary air filtration media technology into Quality's commercial product lines.
The pilot program is expected to span approximately 8 to 12 weeks and is designed to assess product compatibility, manufacturing scalability, and end-product performance under real-world commercial conditions. During the pilot period, the teams will collaborate on defining the commercial and technical framework for a potential long-term supply arrangement.
This initiative advances Zentek's strategy of following its principal commercialization pathways as outlined in the Company's Management Discussion and Analysis dated February 17, 2026, which focuses on integrating intellectual property into existing filtration products and leveraging existing infrastructure through partnerships with established manufacturers. The Company believes the pilot with Quality represents the first material step toward validating these pathways in the U.S. air filtration market and represents a repeatable, partnership-led commercialization model that can be leveraged in other markets as well.
The Company was introduced to Quality by Altek Advanced Materials Inc. ("Altek"). If the Company is successful in negotiating a licensing agreement, Altek would be entitled to a royalty as per the terms of the binding letter of intent announced on September 3, 2025.
U.S. Air Filtration Market
The U.S. represents a highly attractive market for advanced HVAC air filtration solutions, supported by both scale and structural demand drivers. Independent industry research estimates the U.S. air filter market is projected to reach approximately US$7.3 billion by 20321, driven by commercial, healthcare, and institutional buildings requiring higher‑performance filtration solutions. At the same time, building decarbonization is accelerating, with the U.S. Department of Energy estimating that buildings account for more than one‑third of U.S. greenhouse gas emissions and approximately 75% of U.S. electricity consumption2, placing HVAC system efficiency at the center of regulatory and economic priorities. The Company believes this convergence creates a compelling opportunity for differentiated filtration technologies that can enhance air quality without increasing system energy demand. Through its partnership with Quality, Zentek believes its proprietary air filtration media technology has the potential to support Quality's growth platform in the U.S. by enabling advanced, energy‑efficient filtration products aligned with these customer, regulatory, and sustainability objectives.
Given the U.S. air filtration market is several times the size of the Canadian market, it represents a key strategic priority for Zentek. The Company expects to continue evaluating regulatory requirements for EPA registration in parallel with this pilot program, positioning the Company to advance its evaluation of U.S. regulatory requirements while working with a validated manufacturing partner to potentially enter the U.S. market.
Management Commentary
Amy Spottswood, Chief Executive Officer of Quality Filters Inc., stated: "We are interested in evaluating advanced coating technologies that can enhance the performance and value proposition of our filtration products. This pilot program will allow us to assess Zentek's proprietary air filtration media technology under our standard production conditions and evaluate its potential for integration into our commercial product offerings."
Mohammed (Moe) Jiwan, CEO of Zentek, commented: "This pilot program with Quality Filters represents a meaningful step forward in our principal commercialization pathways. Rather than building manufacturing capacity from the ground up, we are working to integrate our intellectual property directly into the production lines of an established filter manufacturer. The U.S. market offers both a large addressable market and a regulatory framework that supports multiple potential pathways to commercialization. We are extremely excited to work with the Quality family and look forward to demonstrating our unique performance advantages in their production environment over the coming weeks."
