IAQ Monitors -Seeing the Invisible or Nothing At All?

Consumer-grade monitors and sensors that measure fine particulate matter (PM) and volatile organic compounds (VOCs) are increasingly being used to evaluate indoor air quality (IAQ) and to control HVAC systems. And while there is now solid evidence that some PM sensors are reliable and provide actionable data to manage exposures and reduce risk, there is not yet an operating rating system to enable homeowners or contractors to assess the quality of individual products, or their relevance to different sources. The value of information from VOC sensors is even more uncertain. This session will present an up to date guide on how available sensors can be used effectively to manage IAQ and their limitations. Joe Medosch will share what he learned from deploying sensors in his own home, including data on PM and VOCs from cooking and comparisons across more than a dozen devices. We will will also present. on the state of the integrated technologies that are using IAQ sensors to control ERVs and other ventilation equipment; forced air heating, cooling and filtration; and humidity; and also being used to monitor the duct system. You will learn way more than we can summarize in 200 words!
