1. A multi-device chassis air filter characterization system, comprising:
a multi-device chassis;
an air filter that is included on the multi-device chassis;
a plurality of computing devices that are housed in the multi-device chassis, wherein each of the plurality of computing devices is configured to:
determine that a current time corresponds to a predetermined air filter characterization time period; and
operate, in response to determining that the current time corresponds to the predetermined air filter characterization time period, a cooling system in that computing device at a predetermined cooling system operating level for the predetermined air filter characterization time period,
wherein a first computing device that is included in the plurality of computing devices is configured to:
measure an air filtering characteristic provided by the air filter during the predetermined air filter characterization time period; and
determine, based on the air filtering characteristic, whether to generate an air filter replacement alert.
