Abstract
A method may include, in response to an indication that a clean air filter has been installed in an information handling system, setting a speed of an air mover of the information handling system to a predetermined filter testing speed, determining a clean filter baseline airflow as an airflow driven within the information handling system responsive to the predetermined filter testing speed, calculating a threshold filter failure airflow based on the clean filter baseline airflow, and periodically executing filter fouling tests. Each filter fouling test may include setting the speed of the air mover to the predetermined filter testing speed, determining a resulting airflow within the information handling system responsive to the predetermined filter testing speed, comparing the resulting airflow to the threshold filter failure airflow, and communicating an alert responsive to the resulting airflow being below the threshold filter failure airflow.
