本发明公开了一种滤清器无纺布，该滤清器无纺布包括：依序层叠设置的表层、中间层以及底层；其中，表层设置为精细过滤层，通过静电纺丝纳米纤维制得；中间层设置为主过滤层，通过高效驻极熔喷聚丙烯制得；底层设置为支撑层，通过纺粘聚酯制得；表层面密度设置为0.3‑0.8g/m²，厚度设置为5‑15μm，以此形成超细限位网络；中间层面密度设置为15‑30g/m²，厚度设置为0.3‑0.6mm，驻极体采用氟化处理及电晕驻极；底层面密度设置为20‑40g/m²，厚度设置为0.15‑0.3mm。本发明的滤清器无纺布采用一步法在线复合将纳米纤维直接沉积在熔喷层上，再热压复合纺粘底层，减少生产步骤，并增强层间结合力，同时，仅在滤材表层复合纳米纤维，能够大幅降低成本。
