Product Description
PET Melt-Blown Air Filter Media is a high-performance synthetic filtration material manufactured through the melt-blown extrusion process, which produces ultra-fine polyester microfibers with diameters ranging from 2 to 3.5 micrometers . This media is supplied in rolls and serves as a critical filtration layer for HVAC and AHU systems requiring efficient sub-micron particle capture.
The melt-blown process creates a dense, randomly-oriented fiber web with high surface area and small pore size, enabling superior filtration efficiency for particles as small as 0.3 microns.
PET melt-blown media offers exceptional fine-particle capture capability while maintaining manageable pressure drop levels .

Product Features
PET Melt-Blown Air Filter Media offers exceptional fine-filtration performance for demanding air handling applications.
Superior Sub-Micron Capture – The ultra-fine microfiber structure enables efficient capture of particles down to 0.3 microns, making it ideal for high-efficiency filtration applications where particle removal is critical .
Depth-Loading Filtration – The dense three-dimensional fiber network traps particles throughout the media thickness, providing high dust-holding capacity and extended service intervals for HVAC systems.
High Porosity with Low Resistance – Despite its fine fiber structure, the media maintains 90-94% porosity, ensuring excellent airflow permeability and manageable pressure drop during operation .
Chemical and Moisture Resistance – PET fibers resist degradation from humidity, mild acids, and chemicals, ensuring stable filtration performance in diverse environmental conditions.
Consistent Filtration Efficiency – The melt-blown process ensures uniform fiber distribution, delivering reliable and predictable efficiency across the entire roll.
