Airflow Measurement for Air Cleaners, Purifiers and Sanitizers
The covid-19 pandemic has generated an increased interest in airflow and cleaning the air. Air cleaners, also referred to as air purifiers or sanitizers, use differing technologies including HEPA filtration, activated carbon filtration, ultraviolet (UV) germicidal irradiation, or multiple technologies such as filtration with UV disinfection. The ASHRAE Position Document on Filtration and Air Cleaning provides information on these and other technologies.
