Claim 0:
1. A building management system (BMS) for filtering a fluid within a building, the system comprising:
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; 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
a pollutant management system 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 data from the one or more sensors; 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.
