Abstract The demand for advanced applications in nanofiber technology has been increasing in recent years, one of which is in the field of particulate matter filtration. This review highlights the recent developments and applications of electrospun nanofibers as particulate matter filtration membranes. Electrospinning is chosen as a nanofiber fabrication method because of its high versatility, reliability, simplicity, and scalability. Besides adjustable fiber geometry affecting filtration efficiency, high surface hydrophobicity and high-temperature resistance have become the main attributes required by nanofibrous membranes for particulate matter filtration to enable their applications in harsh environments, such as industrial combustion and vehicle emission. Various organic and inorganic nanofiber materials are explored, in which their strengths and drawbacks are evaluated. Future research of nanofiber-based particulate matter filtration membranes is encouraged to overcome the currently faced challenges by exploring additional properties, for instance, antimicrobial and antifouling capabilities, optimizing nanofiber morphology, and employing environmentally friendly materials.
