1. A system comprising:
a sensor;
an airflow generator coupled to an airflow guide configured to direct airflow from the airflow generator toward and past the sensor; and
one or more processors and a non-transitory computer readable storage media embodying instructions coupled to the one or more processors, the one or more processors operable to execute the instructions to:
acquire data about an operational state of the system, wherein the operational state is a factor in generation of at least one air contaminant that is generated by operating the system; and
control the airflow from the airflow generator based on the data about the operational state of the system.
