High Precision Polyester Mesh

Dust is prevented from entering the PC by a high precision polyester mesh. The filament diameters of this mesh are smaller than the openings between them. This allows more air through the filter while still stopping the dust. These filters are the only computer dust filters we have come across that guarantee to keep out specific size and larger dust particles due to their mesh openings being very accurate.
