ZENTEK ADDS DIRECT-TO-CONSUMER CHANNEL FOR ZENGUARD, ALONGSIDE ITS GOVERNMENT AND INSTITUTIONAL SALES

Zentek Ltd. has launched its ZenGuard on-line store. The store is an additional sales channel. It adds direct sales to households alongside Zentek's existing government and institutional channels, which continue unchanged.

Customers can order ZenGuard air filters for residential furnaces and air handlers, along with ZenGuard masks, and have them shipped to their door from Ontario.

ZenGuard is a Canadian innovation: a graphene-based filter coating developed by Zentek in Ontario, patented and made in Canada.

The government of Canada supported ZenGuard from development through to purchase. Under the Innovative Solutions Canada testing stream, the National Research Council of Canada validated ZenGuard in a simulated classroom. In May, 2026, Innovative Solutions Canada added ZenGuard enhanced air filters to its pathway to commercialization source list, which lets any federal department or agency buy them directly for three years. Government of Canada orders are placed through Zentek's standing offer with Public Services and Procurement Canada. On Oct. 1, 2026, Zentek shipped its first government of Canada ZenGuard order under that standing offer. The same filters are now available to Canadian households.

In independent testing at LMS Technologies, an ISO 17025 accredited lab, a ZenGuard-coated filter captured 74.9 per cent of a test virus in a single pass, compared with 57.0 per cent for the same filter media without the coating (July, 2026). That is about 30 per cent more captured by the same filter. The same lab found no detectable release of the coating from the filter (March, 2025, after 20 months of aging). The shedding result was previously announced in the company's news release dated March 12, 2025. Earlier ZenGuard viral filtration results were announced in news releases dated Sept. 6, 2023, and June 12, 2025, and National Research Council of Canada results were described in the news release dated May 13, 2026.

These are laboratory results under controlled conditions, not measurements in a home. Results may vary depending on HVAC configuration, airflow, filter fit, operating conditions, replacement frequency and other factors.

"ZenGuard was invented, tested and patented by a Canadian team, and it is made here. The government of Canada helped us prove it and now buys it. I want to thank Innovative Solutions Canada, the National Research Council of Canada, and Public Services and Procurement Canada for backing made-in-Canada innovation from the lab, through commercialization, to a purchase order. Today Canadians can order it to their door," said Mohammed (Moe) Jiwan, chief executive officer of Zentek.
