Improving IAQ with Effective Air Filtration by In-Room Air Cleaners

Join Ms. Kathleen Owen, MS, ASHRAE Fellow, Owen Air Filtration Consulting, at the WFI 2022 Annual Conference on December 6, 2022. She will be addressing improvements to indoor air quality by in-room cleaners.

Improving IAQ with Effective Air Filtration by In-Room Air Cleaners

Indoor Air Quality (IAQ) is a major goal in all types of indoor environment. In our quest for Sustainability, we must not lose the goal of safe air for breathing and for equipment. When building shells are tightened to reduce cooling or heating load or to prevent wildfire smoke from entering, we must find ways to maintain good quality air. Certainly, a certain amount of outdoor air must be brought in to dilute some contaminants such as CO2, but many air cleaning can mitigate many issues. When running a whole building system is too expensive or too intermittent or a building does not have an HVAC, In-Room Air Cleaners can help keep the air breathable. This talk introduces the general concepts including what contaminants can be removed and how; how to size air cleaners for specific spaces; how to compare costs for IRAC vs HVAC-mounted devices; and some cautions on things to avoid. A new IRAC chapter is coming in the new ASHRAE handbook (2023); this talk presents much of that material to help filtration experts prepare to use IRAC as part of their IAQ solutions.
