Abstract: A method may include, during a filter fouling test of an air filter, determining if the air mover is operating below a first predetermined filter testing speed, in response to the air mover operating below the first predetermined filter testing speed, operating the air mover at the first predetermined filter testing speed and determining an indicator of filter degradation of the air filter responsive to the first predetermined filter testing speed, in response to the air mover operating above the first predetermined filter testing speed, operating the air mover at a second predetermined filter testing speed significantly greater than the first predetermined filter testing speed and determining the indicator of filter degradation of the air filter responsive to the second predetermined filter testing speed, and determining if the indicator of filter degradation is below a respective filter failure threshold.

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.
