Air Filtering Meltblown Nonwoven Air Filtering Meltblown Nonwoven is kind of superfine fiber nonwovens material made from food grade PP through the meltblowing process. The fiber diameter can reach 0.5μm�2μm, 10 times thinner than ordinary fibers. The ultra fine fibers with unique capillary structure increase the fiber number and surface area per unit area and endow meltblown nonwovens with very good filtering performance, making them suitable for use as air filtering materials with medium or high efficiency.
