1. An information handling system comprising:
a chassis including a bezel;
a filter in physical communication with the bezel of the chassis;
a force sensing resistor in physical communication with the bezel and with the filter; and
a baseboard management controller to communicate with the force sensing resistor, the baseboard management controller to:
receive a voltage level from the force sensing resistor;
based on the voltage level, determine a clogged level for the filter;
determine whether the clogged level is greater than a threshold level; and
in response to the clogged level being greater than the threshold level:
determine that the filter needs to be replaced; and
provide a filter clogged message.
