Course Objectives:

This is an introductory course for air filtration. It will provide you an overall understanding of air filtration principles, technologies, and applications in various market segments, such as HVAC, transportation, industrial dust removal, gas turbines, paint spray booths, clean rooms, hot gas filtration, air purification, personal protection, etc. The current emerging high demands for facemasks and air filtration associated with COVID-19 for public safety and health will also be discussed, along with new developments and trends in the global filtration market.

1. Air Filtration Fundamentals

a. Airborne particles – sizes, optical-aerodynamic diameters, settling velocity

b. Filtration mechanisms

c. Application of mechanisms to HVAC filters, HEPAs, facemasks

d. Charged media and discharge

2. Air Filtration Response to COVID-19

a. Transmission routes and risk-minimizing strategy

b. Surging demand for air filtration

c. New requirements and guidelines for air filtration

3. Market Applications

a. HVAC Filters

b. Air Filters in Transportation

c. Industrial Dust Removal

d. Gas Turbine filtration

e. Hot Gas Filtration

f. Personal Protection

g. Air Purifiers

h. Specialties

4. New Development and Trends

Instructor Biography

Kathleen Owen

ASHRAE Fellow

President @ Owen Air Filtration Consulting, LLC

Ms. Owen, ASHRAE Fellow, is an expert in air filter/cleaner filtration efficiency and test method development. She is currently the principle investigator (PI) on the ASHRAE projects conducting Interlaboratory Studies (aka Round Robins) on the ASHRAE 52.2 and 145.2 methods for testing particle and gas-phase air cleaner efficiencies.  Previously, she worked on the ASHRAE and US EPA projects that developed ASHRAE air cleaner efficiency test methods 52.2 (for particles), 145.2 (gases), and 185.1 (UV-bioaerosol). She also developed chamber test methods for gases and bioaerosols based, in large part, on the Association of Home Appliance Manufacturers (AHAM) CADR test method.  She was the first chair of ASHRAE committee SSPC 145 and is the current chair of ASHRAE 52.2.  She is also the research subcommittee chair for TC2.3 Gaseous Contaminants and is a member of SSPC 185, TC2.4, TC2.9, and TC2.3, and of the US TAG to ISO 142. During her 33 years  at RTI International, she ran ASHRAE 1360-RP and worked on many ASHRAE and EPA projects on air cleaning and air quality including the recent EPA EIP on air cleanup in VI situations.  She ran the RTI commercial air cleaner test lab for 20 years. Her BS in chemical engineering is from North Carolina State University, and her MS in Air Pollution Control Engineering is from the University of North Carolina at Chapel Hill.

Dr. Christine Sun


President of Waterloo Filtration Institute

Dr. Christine Sun, President of Waterloo Filtration Institute, is a renowned technical and market expert in the global filtration industry. She is currently the Operation Chair for the 13th World Filtration Congress. With over 30 years of experience in academia and the industry, she has an in-depth knowledge of filtration, extensive hands-on expertise in product development, has over 100 technical publications and patents. She is also actively involved in many air/liquid filter test standard developments.

Dr. Sun received her Ph.D. from Tsinghua University, Beijing, China, and Executive Certificate from Northwestern University - Kellogg School of Management. From 2004 to 2011, Dr. Sun worked for Freudenberg Filtration Technologies as R&D manager, and then served as Technology Director for Donaldson from 2011-2013. She was the AFS Chair from 2016-2017 and received the AFS Fellow Award in 2019, Sr. Scientist Award in 2012, and the best paper awards from INDA in 2008. She also serves as an editorial board member for Textile Research Journal and Journal of Industrial Textiles.

Over the years, Dr. Sun has developed many professional courses including: “Nanofiber Technologies in Filtration” (AFS, 2013), “Filter Media Training Course” (INDA, 2014-17), “Air Filtration Market, Technologies and Trends” (AFS, 2015), “Filter Media Market and Technologies” (WFC12, 2016), “Filter Media Technologies” (AFS, 2019), and “Facemask Media Technologies (WFI 2020). Dave Rousse, INDA’s president, stated ‘The addition of INDA’s Nonwoven Filter Media Training Course was tremendously received’. Dr. Sun became known as “a brilliantly articulate and lively instructor who is skilled in guiding filter media professionals through the complexities of the air, liquid, and nanotechnology markets.”
