Course Objective
This course provides a foundational and practical understanding of air filter testing and evaluation. It introduces key principles of air filtration testing, outlines commonly used test methods, and highlights their applications across a range of industries. Participants will explore essential filtration terminology and gain insight into the broad spectrum of available test methods. Emphasis will be placed on critical performance metrics such as filtration efficiency, pressure drop, dust-holding capacity, and service life, along with the variables that influence test outcomes.
The course includes an in-depth overview of global air filtration/cleaning standards, including ASHRAE 52.2, 185, ISO 16890, and ISO 29463 and delves into ASHRAE Standard 241, a new Standard that allows use of various methods of filtration and air cleaning. Recent developments, emerging trends, and future opportunities in air filtration testing will be explored in a closing panel discussion featuring leading industry experts.
