Abstract Electrospun nanofibers can lower health risks linked to exposure particulate matter pollutants. On the other hand, nonbiodegradable polymeric materials increase issues related their disposal and generation of hazardous microplastics. Hence, this research aims develop a nanofibrous membrane filter composed polyvinyl alcohol (PVA) as biodegradable polymer, boric acid (BA) using an electrospinning technique. This study investigates effect BA on fire behavior, mechanical properties, filtration performance nanofiber membranes. The morphological results show that samples containing have no beads nanofibers. Incorporating into PVA membranes reduce peak release heat by ≈39%. Additionally, offer enhanced properties tensile strain (≈3.6%) Young's modulus (up ≈45%). optimized BA/PVA also demonstrate superior efficiency (above 99.9% for 300 nm particles) low‐pressure drop (150 Pa at 5.3 cm s −1 airflow velocity). Therefore, improve not only behavior than those pure nanofibers, but performance.
