ZENTEK'S ZENGUARD ENHANCED AIR FILTRATION MEDIA COMPLETES QUALIFICATION PROGRAM WITH QUALITY FILTERS INC.; FIRST U.S. COMMERCIAL ORDER RECEIVED

Quality Filters Inc., Zentek Ltd.'s United States-based manufacturing and distribution partner headquartered in Robertsdale, Ala., has 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 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 $7.4-billion (U.S.) by 2032, driven by commercial, health care 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 per cent of total energy used in the U.S. and approximately 75 per cent of U.S. electricity consumption, placing HVAC system efficiency at the centre 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.

Management commentary

"ZenGUARD enhanced air filters performed to our specifications through a rigorous validation process, and we are pleased to be moving into commercial production. We look forward to introducing this technology to our customers," said Amy Spottswood, chief executive officer of Quality.

"Completing the validation program and receiving Quality's first commercial order is a meaningful step in Zentek's U.S. commercialization strategy. Quality confirmed that ZenGUARD enhanced air filtration media meets their specifications, and we are now moving from testing to commercial execution. Quality Filters is exactly the type of reputable, innovative manufacturing partner we want to work with as we bring ZenGUARD into the U.S. market, and we look forward to supporting them as they integrate ZenGUARD technology into their product offerings," said Mohammed (Moe) Jiwan, chief executive officer of Zentek.
