Abstract

Abstract : In this study, the electrospinning process modifies the commercial polyester filter media to increase filtration efficiency. The polyethylene terephthalate (PET) solution produces electrospun fiber on commercial polyester filter media at various rotation speeds and durations. The PET concentration and electrospinning applied voltage were adjusted accordingly to obtain bead-free electrospun fibers. As a result, the modified filter media's filtration efficiency is approximately two times higher than the commercial polyester filter media at 300 rpm and 5 hours of electrospinning duration. Furthermore, the efficiency of the single unit modified filter media is 53.76% with an airflow resistance of 39.2 Pa and quality factor of 0.01968 Pa −1 which are comparable to the combination of two units' air filters. Thus, replacing two units' air filters having a primary and secondary filter with a single unit modified filter media is justifiable.
