Zentek Validates ZenGUARD Enhanced Air Filters for ASHRAE Standard 241 Compliance with High-Performance Test Results

Zentek Ltd. has announced new test results validating its ZenGUARD Enhanced Air Filters as a high-performance solution for ASHRAE Standard 241 compliance. The filters achieved an average infectious aerosol removal efficiency of 42% compared to an untreated filter's 16%. These strong results align with previous tests performed with bacteriophage Phi6, a surrogate for SARS-CoV-2 and other enveloped viruses. ZenGUARD Enhanced Air Filters are the only technology that can control infectious aerosols while working with existing HVAC units, extending filter life, and reducing changeout frequency.
