ZenGUARD Enhanced Air Filters

Zentek's Business Development team led by Ryan Shacklock, Senior Vice President, Strategy and Business Development, has been executing an extensive education program for ZenGUARD Enhanced Air Filters. This includes attending HVAC industry events in both the United States and Canada where technical details and the latest developments of ZenGUARD Enhanced Air Filters are highlighted to potential customers, property managers and filter manufacturers and distributors.

The American Society of Heating and Air-Conditioning Engineers (ASHRAE)

Zentek representatives attended the 2024 ASHRAE Winter Conference in Chicago, Illinois in January 2024 to share technical details of ZenGUARD's impact on Minimum Efficiency Reporting Value ("MERV")-rated HVAC filters. Following this event, the team completed and submitted an extended abstract to ASHRAE titled: "ASHRAE Standard 241 and Graphene Silver-Coated MERV-A 9-A Filters: A Case Study." The abstract was coauthored by Deepak Sridhar, Kathleen Owen, Ryan Shacklock, and Colin van der Kuur.

As context for this study, several organizations including the Centers for Disease Control and Prevention in the United States are advocating for improved indoor air quality via several strategies, including using higher MERV-rated HVAC filters. Similarly, ASHRAE introduced Standard 241, Control of Infectious Aerosols, which outlines specific recommendations for buildings of various types to reduce the risk of disease transmission. In certain instances, these recommendations have led to challenges stemming from:

Incompatibility of HVAC systems with higher MERV-rated filters

Higher filter and maintenance costs

Increased energy demand and emissions from conditioning additional outdoor air

Elevated energy demand and emissions from increased airflow restrictions associated with higher MERV-rated filters

This case study, which makes use of the approach outlined in the ASHRAE Standard 241, will be presented at the ASHRAE Annual Conference on June 23, 2024, in Indianapolis, Indiana.
