Abstract: A method for providing filtered air to a zone of a building includes operating an air handler to pass unfiltered air through a filter and output filtered air to the zone of the building. The method includes determining an amount of filtered air provided to the zone of the building by the air handler. The method includes determining if additional air filtration is required to satisfy at least one of a desired amount of clean airflow or a desired reduction of a risk of infection. The method includes activating an in-zone filtration device and operating the in-zone filtration device to draw air from the zone into an inner volume, filter the air, and recirculate the filtered air to the zone of the building in response to determining additional air filtration is required.

Abstract: A building management system can include one or more computer-readable storage media. The one or more computer-readable store can have instructions stored thereon that, when executed by one or more processors, cause the one or more processors to obtain, from a regional air quality data source, a first set of outdoor air quality data, wherein the first set of outdoor air quality data represents air quality measured for a region, obtain, from one or more local sensors coupled to and/or positioned proximate to the building, a second set of outdoor air quality data, wherein the second set of outdoor air quality data represents air quality measurements at one or more positions at or near an exterior of the building, and generate, using the first set of outdoor air quality data and the second set of outdoor air quality data, an air quality assessment for the building.
