Abstract
A switchable filtration system for a heating, ventilation, air conditioning, and refrigeration (HVACR) system is disclosed. The filtration system includes a first filter, a second filter, a switching apparatus, and a controller. The controller is configured to determine an air quality score. When the air quality score exceeds a predetermined threshold, the controller controls the switching apparatus to switch the first filter out of an active airflow path. When the air quality score is at or below the predetermined threshold, the controller controls the switching apparatus to switch the first filter into the active airflow path.
