Synthetic Fibre Filter Media

Synthetic Filter Fibre Media

Synthetic fibre filter media is produced by blending chemicals with fibre-forming materials using needle spinning and thermobonding techniques. That creates twisted, multi-directional materials with varying weights and thicknesses, ensuring excellent dust holding capacity. It is water-resistant and provides high-level filtration for low airflow applications. The shatterproof synthetic threads prevent harmful fibres from entering the atmosphere.

PAR Group offers different grades of synthetic air media in various colours and efficiencies. Standard classes include gross (G3 and G4) and medium (M5) filtration, available to purchase on PAR Direct using the 'Buy Online' button at the top of the page. We can supply different grades (WREU, F6, F7 and F8) and customised options like pre-cut pads or converted filter media products. For more information, contact our sales team.


G3 and G4 synthetic fibre filter media filter coarse dust particles sized > 10 µm in applications such as pre or primary filters in heating, ventilation and air conditioning (HVAC) systems, pleated media support, panel filters and electronic cabinets.

G3 filter is similar to G4 filter media in having a final pressure drop of 250 Pa. However, G3 has an > 80 AM < 90% average arrestance with synthetic dust, whereas G4 has a > 90% average arrestance with synthetic dust per EN 779:2012.

M5 input media is primarily used as a ceiling filter in paint and spray booths and is suitable for applications which require a filter with a < 40 EM < 60% average efficiency for 0.4µm particles. This media is used to filter fine dust particles sized between 1 and 10µm.

Key Features

  • Excellent dust retention.
  • Environmentally friendly, it does not release fibres into the air during application. 
  • Commonly used in food processing industries.
  • High resistance to water.


  • Conforms to EN 779:2012 for determining air filter performance.
