"multiple sizes of heating, ventilation and air conditioning ("HVAC") air filters."

HVAC stands for heating, ventilation and air conditioning — the systems that control temperature, airflow and indoor air quality in buildings. Investors care because HVAC drives operating costs, energy use, tenant comfort and regulatory compliance; like the engine and insulation of a building, efficient modern systems can lower bills, reduce repair and replacement spending, and preserve property value, while outdated units can create unexpected expenses and vacancy risk.

Guelph, Ontario--(Newsfile Corp. - July 7, 2026) - Zentek Ltd. (TSXV: ZEN) (NASDAQ: ZTEK) ("Zentek" or the "Company") is pleased to announce that Quality Filters Inc. ("Quality"), its U.S.-based manufacturing and distribution partner headquartered in Robertsdale, Alabama, has successfully completed a validation and qualification program for ZenGUARD™ Enhanced Air Filtration Media and has subsequently placed its first commercial order for 244 rolls to support production of multiple sizes of heating, ventilation and air conditioning ("HVAC") air filters. This milestone marks the transition from the pilot evaluation program announced on March 4, 2026, to commercial production and market launch activities.

The validation and qualification program was designed to assess product compatibility, manufacturing scalability, and end-product performance under Quality's commercial production conditions. Quality has confirmed that performance results met its qualification requirements and production specifications. As a result of the successful program, Quality has initiated its first commercial order for ZenGUARD™ Enhanced Air Filtration Media. The initial order is intended to support commercial production and market launch activities.

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$7.4 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 consume 40% of total energy used in the U.S. and approximately 75% of U.S. electricity consumption², placing HVAC system efficiency at the center of regulatory and economic priorities. The Company believes these market trends create a compelling opportunity for filtration technologies that can enhance air quality without increasing system energy demand. Quality's first commercial order for ZenGUARD™ Enhanced Air Filtration Media represents Zentek's first step in accessing this growing market through an established U.S. manufacturing partner.
