ZENTEK PROVIDES REGULATORY UPDATE ON ZENGUARD ENHANCED AIR FILTERS

Zentek Ltd. has received a letter from Health Canada noting that Health Canada is considering the classification of ZenGuard enhanced air filters and inviting Zentek to submit additional information regarding appropriate regulatory classification.

ZenGuard enhanced air filters were being assessed by the Health Canada Pest Management Regulatory Agency (PMRA) for registration under the Pest Control Products Act. On Oct. 31, 2024, the company announced that it had withdrawn its submission to PMRA for its ZenGuard enhanced air filters to pursue a more appropriate pathway to commercialization in Canada. Accordingly, on Nov. 27, 2024, the company announced its intention to market ZenGuard enhanced air filters as a Class I medical device under its existing MDEL, similar to its surgical masks.
