Abstract: A building management system (BMS) for filtering a fluid within a building is shown. The system includes one or more sensors configured to measure one or more characteristics of a first fluid within an air duct of the BMS and measure one or more characteristics of a second fluid after the second fluid has been filtered. The system further includes a pollutant management system configured to receive data from the one or more sensors and control a filtration process. The filtration process selects a filter of a plurality of filters based on at least one of a level of the one or more characteristics of the first fluid or the one or more characteristics of the second fluid.

Abstract: A device for use in a building automation system includes a first circuit configured to receive non-electrical energy from an environment in which the device is placed and convert the non-electrical energy to electrical energy. The electrical energy is used to power the first circuit. The first circuit configured to sense a parameter based on the non-electrical energy. A communications interface configured to be powered by the electrical energy and configured to communicate the sensed parameter to the building automation system.
