Clean Air Strategies for Public Health

Updated: Nov 15, 2022

WFI Education Webinar

February 22, 2022, 8:00 -10:00 am EST

This education webinar aims to provide you with the latest developments in clean air strategies for public health. Our distinguished speakers and panel experts will answer your questions live online. Chris Muller, Director IEQ Technical Services of AAF Flanders, ASHRAE Distinguished Lecturer, will address Air filtration technologies for clean indoor & outdoor air and what the requirements are for IAQ control and healthy buildings. It will cover ambient air quality, current and developing enhanced air cleaning technologies, and methods being used to evaluate the effectiveness of these various technologies. Tyler Smith, Vice President – Healthy Buildings, Johnson Controls, will address the multiple value propositions of smart buildings and how technology can be leveraged to ensure IAQ, wellness, and decarbonization are an “and” proposition, not an “or” proposition. John Zhang, a Lead Specialist of 3M, will present a recent study on indoor airborne particle control by HVAC filters and room air purifiers to help us understand the relationship between filter efficiency and CADR (clean air delivery rate) and reduction of the PM (particulate matter) concentration in a house. Kathleen Owen, ASHRAE Fellow and member of the ASHRAE ETF, past Chair of ASHRAE 52.2 and SSPC 145, will update current ASHRAE ETF recommendations for filtration/air cleaning and on options that can be implemented quickly.
