1. A method of managing hardware components positioned in a chassis of a data processing system, the method comprising and by a hardware processor of the data processing system:
identifying an occurrence of a particulate accumulation elimination event, the hardware processor being coupled to a memory of the data processing system, the memory storing instructions that when executed by the hardware processor causes the hardware processor to perform the method, and the hardware processor and memory being ones of the hardware components;
based on the identifying of the occurrence:
activating a field applicator to apply an electric field to a filtration media of a filter covering an opening in a chassis of the data processing system to charge at least a portion of particulates accumulated on the filtration media to a charge level to obtain charged particulates, the opening facilitating airflow through the chassis to dissipate heat from the hardware components;
while the particulates are being charged to the charge level, identifying an occurrence of a charged particulates discharge event;
based on the occurrence of the charged particulates discharge event:
grounding at least a frame of the filter to discharge the charged particulates;
while grounding the at least the frame of the filter, identifying that the particulate accumulation elimination event has ended; and
deactivating the field applicator and allow the at least the frame to electrically float based on the end of the particulate accumulation elimination event.
