Elmarco Talks: Using Air Cleaning Devices with ASHRAE Standard 241
Join us for the final Elmarco Talk of Season 2! We're closing this season with a highly relevant and engaging topic: Using Air Cleaning Devices with ASHRAE Standard 241, presented by Kathleen Owen and Jonathan Rajala.
What will be discussed?
Everything helps in Standard 241! This new Standard “Control of Infectious Aerosols” is written to provide reduced risk during Pandemics (or IRMM). It requires users to provide specific amounts of clean or cleaned air per person in occupied spaces, then lets you choose from multiple options to meet their air needs. Once the air needed by your building or space and where it is needed are determined, you decide which solutions to use. You can bring in outdoor air (assumed clean of human pathogens), reduce occupancy, or use air filters, ultraviolet light (UV), reactive air cleaners (RAC), and other air cleaners to make your building safer. Or you can use some of each of the different options. This talk introduces Std 241 with emphasis on how air cleaners can be used and what requirements are made to allow them to be used.
