Electrostatic Filter (PEF)

High-Performance Filter through Frictional Charging

With its unique three-dimensional structure, this filter offers higher air permeability and collection capacity compared to conventional nonwoven fabric filters. By blending different types of fibers, the pile becomes electrostatically charged, allowing it to capture particles in the air through the force of static electricity. In terms of dust removal efficiency (DOP method), it has been confirmed to have a higher removal rate compared to traditional electrostatic nonwoven fabrics (based on our comparison).
