Ldays, the quality ofvehicle's cabin air has become one of the health concerns a lffiers. Typical air filters used in an air conditioning system of a vehicle are m:1fiber materials such as fiberglass and polymeric materials. Nanofibers have a tial to be used as high efficient filter materials due to their nanoscale diameters facturers claim that filters made of nanofibers can trap dusts or particles with % efficiency. However, there is limited information available on the effectiven ospun nanofiber filter media in filtering submicron particulates. Therefore, this ned at developing and studying the performance of nanofiber-coated filtering submicron particles. The filters were incorporated with electrospun ny ibers at 1 Ok V of applied voltage and 10 em spinning distance. The coated filten lced at varying collection times ranging from 1 to 10 minutes. The filter sample~ I using a dedicated test rig to simulate an actual air conditioning system. Parti :r (PM) measurement technique was used in measuring air particle concentnt across the filter. The morphology of the nanofiber coated filters was an on Scanning Electron Microscope (SEM) micrographs. It was observed thospun nanofibers have diameters ranging from 1 04 nm to 11 7 nm. The nano:i filters showed a significant improvement of around 33% in efficiency who spinning collection time was 10 minutes compared to control samples. The revealed that a longer electrospinning collection time produced a thicker la~ibers producing filters with higher filtration efficiency for capturing fine partirs.
