优选地，所述空气过滤层的厚度为1～100mm。
一种纳米抗菌空气过滤非织造材料的制备方法，包括如下步骤：
a.选择纳米级的聚丙烯纤维，并将聚丙烯纤维进行改性处理，具体是配制抗菌剂，将配制的抗菌剂喷淋在聚丙烯纤维表面上，然后静止0.5～1小时，进入烘房烘干，制得聚丙烯纳米抗菌纤维；
b.将用于空气过滤层的纤维和上述步骤a中制得的纳米抗菌纤维经开松、给棉、梳理、铺网、主梳理步骤后，在成网的空气过滤层表面涂布粘胶点，并利用热轧双辊机进行热粘合加固。
c.成卷、分切后得成品。
本发明的有益效果为：本发明提供了一种纳米抗菌空气过滤非织造材料，该非织造材料通过复合层结构改造，增强了抗菌能力和空气过滤吸附能力，可应用于空气过滤装置，该非织造材料不仅使用寿命增长，而且效率提高。本发明的工艺利用热粘合复合的热轧工艺，该工艺简单，效率高。
