Claim 7:
8. A controller for filtering a fluid within a building management system (BMS), the controller comprising:
a processing circuit comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving, via one or more sensors, a first set of sensor data comprising one or more characteristics of a first fluid within an air duct of the BMS;
receiving, via the one or more sensors, a second set of sensor data comprising one or more characteristics of a second fluid after the second fluid has been filtered;
wherein the first fluid is a pre-filtered fluid received in the air duct and the second fluid is a post-filtered supply fluid within the air duct or a post-filtered fluid within a building zone; and
selecting a filter from at least a first filter of a first type or a second filter of a second type different than the first type based on at least one of a level of the one or more characteristics of the first fluid and the one or more characteristics of the second fluid, the first filter of the first type having a first set of filtering characteristics and the second filter of the second type having a second set of filtering characteristics different from the first set of filtering characteristics;
generating a model of the first fluid; and
generating predictions of a composition of the first fluid at a future time using the model, wherein the model is generated based on the first set of sensor data and the second set of sensor data;
wherein selecting the filter further comprises selecting the filter based on the predictions of the composition of the first fluid at the future time.
