Zentek Ltd (formerly known as ZEN Graphene Solutions and before that, Zenyatta Ventures) is a mineral exploration and development company based in Ontario, Canada. Zentek is developing the Albany Graphite Deposit – a rare hydrothermal graphite deposit with the potential to produce a natural, high-purity graphite that may compete in high-technology markets traditionally reserved for synthetic graphite.
The company's high crystallinity graphite can be upgraded without the use of aggressive acid (HF) or high temperature thermal treatment. Zentek has developed an environmentally friendly metallurgical process flowsheet that consists of grinding, flotation and caustic treatment using sodium hydroxide. The company states that it has been able to achieve an extraordinary carbon purity result of >99.9 percent in bench-scale tests, using this proprietary and environmentally friendly purification process.
According to Zentek, current end uses for its graphene materials include composites (concrete, rubber and plastics), energy storage and environmental applications but many more are under development.

Quality Filters places first commercial order for Zentek’s ZenGuard graphene-enhanced air filtration media
Quality Filters Inc. has completed qualification testing of Zentek’s ZenGuard air filtration media and placed its first commercial order, marking Zentek’s entry into commercial production for the US HVAC filtration market.

The initial order includes 244 rolls of ZenGuard filtration media, which will be used to produce various sizes of heating, ventilation and air conditioning (HVAC) filters. This follows a validation and qualification program that evaluated product compatibility, scalability in manufacturing, and filtration performance under commercial production conditions. The pilot program was first announced in March 2026. According to Zentek, the program confirmed that its graphene-enabled filtration media met Quality Filters’ production specifications, enabling the transition from pilot-stage evaluation to commercial manufacturing and market launch.
Zentek secures exclusive three-year federal procurement pathway for ZenGUARD graphene air filters
Zentek has announced that Innovative Solutions Canada ("ISC") has added ZenGUARD™ Enhanced Air Filters to its Pathway to Commercialization ("PTC") source list. This step establishes Zentek as an exclusive supplier within the PTC framework of this type of innovation to the Government of Canada, administered through ISC, for a three-year period, during which any federal department or agency may purchase ZenGUARD™ Enhanced Air Filters directly. The milestone is the culmination of a multi-year collaboration between Zentek, ISC, and the National Research Council of Canada ("NRC").
Indoor air quality became a national priority during the pandemic, particularly in federal buildings, schools, and public spaces where improving filtration without consuming more energy or replacing existing heating, ventilation, and air conditioning ("HVAC") infrastructure presented a significant technical challenge. To help address this need, Zentek was awarded a contract under the ISC Testing Stream - a standing open call for innovative Canadian prototypes - to validate ZenGUARD™ Enhanced Air Filters with the NRC.
Zentek clears regulatory path for graphene-based air filter rollout in Canada
Zentek has announced that it has cleared a key regulatory milestone for its ZenGUARD™ Enhanced Air Filters in Canada, paving the way for commercial deployment of its graphene-based air filtration technology.
The development removes a major source of uncertainty around market entry and enables Zentek to move forward with sales and partnerships across the Canadian HVAC sector. ZenGUARD™ coatings are designed to boost filter performance to MERV 9 levels without increasing pressure drop, energy consumption, or carbon emissions - an important advantage for commercial and institutional buildings where HVAC systems account for a significant share of energy use.
Zentek launches pilot evaluation program with Quality Filters Inc.
Zentek recently announced the initiation of a pilot evaluation program with Quality Filters Inc., 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.
Zentek raises close to US$2 million in recent non-brokered private placement
Zentek has announced that it has closed a non-brokered private placement of units for gross proceeds of CA$2,479,227 (around US$1.8 million).
Proceeds of the Offering will be used for general and administrative corporate purposes.
Zentek announces completion of sale of corporate office
Zentek has completed the sale of its property that houses its corporate office and laboratory space.

Under the terms of the agreement, the Buyer paid Zentek an aggregate purchase price of $2.5 million. The Company will lease back the Property from the Buyer until January 31, 2026, allowing for a transition period and uninterrupted operations.
Zentek announces purchase order from Dexterra Group for ZenGUARD enhanced air filters
Zentek has announced that the Forensic Services and Coroner's Complex ("FSCC") in Toronto, Ontario - where Dexterra Group Inc. provides integrated facility management services - has issued a purchase order for the procurement of ZenGUARD™ Enhanced Air Filters to be used across its facility. The Company is in the process of fulfilling this purchase order.
In addition to anticipated Government of Canada demand through its exclusive procurement opportunity - and its previously announced distribution agreements - the Company believes this represents another data point toward meaningful adoption of ZenGUARDTM Enhanced Air Filters in Canada.
Levidian and Zentek aim to establish graphene-integrated filter manufacturing facility in the Middle East
British climate tech company Levidian and Canadian graphene technology company Zentek have entered an agreement to explore the establishment of a new manufacturing facility in the Middle East.
The companies have agreed to combine their expertise in carbon capture, graphene production and materials development to accelerate the roll out of Zentek’s ZenGUARD™ Enhanced Air Filters and other graphene-enhanced products within the region, while also supporting the production of graphene for other industries.
Zentek completes testing of ZenARMOR™ Corrosion Prevention technology and enters collaboration with Jazeera Paints
Zentek has announced the completion of the Innovative Solutions Canada - Testing Stream contract for ZenARMOR™ nano-pigment in military grade, chromate-free corrosion protection aerospace paint systems, and a new collaboration with Jazeera Paints Company for continued product development and testing.
ZenARMOR™ was evaluated in commercial non-chromate aviation paint systems developed by PPG and Akzo Nobel. Three rounds of corrosion testing were completed from September 2023 to July 2024 and testing followed ASTM B117 (salt spray) and ASTM D5894 (cyclical corrosion) standards. The tests were reportedly successful in demonstrating the effectiveness of ZenARMOR™ nano-pigments in inhibiting corrosion of the aluminum alloy AA2024-T3.
Zentek enters strategic partnership with Filtration Solutions Industrial to manufacture and distribute graphene-enhanced HVAC filters
Zentek has announced the signing of a collaboration agreement (effective April 11, 2025) with Filtration Solutions Industrial Co. (“FSCO”), a leading Saudi-based manufacturer and distributor of air filtration products, to manufacture and distribute ZenGUARD™ Enhanced Air Filters across the Gulf Cooperation Council (“GCC”) region.
Under the terms of the agreement, Zentek will supply FSCO with HVAC filter media coated with its proprietary graphene-silver-based ZenGUARD™ technology — known for its ability to significantly increase viral filtration efficiency. FSCO will produce ZenGUARD™ Enhanced Air Filters that will be marketed and distributed under Zentek’s branding throughout the GCC, including Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Bahrain, and Oman, with the net revenue generated from sales of the products shared between Zentek and FSCO. The term of the agreement is for three years, with additional renewal options.
