Claim 14:
15. A method for filtering a first fluid within a building management system (BMS), the method comprising:
receiving, via one or more sensors, a first set of sensor data of one or more characteristics of the first fluid within an air duct of the BMS;
receiving, via the one or more sensors, a second set of sensor data of one or more characteristics of a second fluid after the second fluid has been filtered; and
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 a comparison between a first level of the one or more characteristics of the first fluid and a second level of 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.
