Zentek Finalizes Testing for ZenGUARD™ Air Filter Commercialization

Zentek Ltd., a technology development company, has completed shelf-life efficacy testing for its ZenGUARD™ Enhanced Air Filters. The tests, necessary for medical device compliance, confirm that the filters maintain viral filtration efficiency (VFE) after 20 months of aging. The results showed a VFE of 38.1%, consistent with initial tests.

The company's filters, classified as a Class I medical device, underwent stability and performance testing as part of regulatory requirements. These tests, including shedding tests, ensure the coating's adhesion remains effective over time. The filters will carry a 20-month expiry label, marking significant progress towards commercialization.

Zentek's CEO, Greg Fenton, expressed satisfaction with the completion of all required testing, emphasizing the filters' role in reducing bioaerosol transmission. The company is now focused on finalizing documentation for production and sale under Canadian regulations.
