Filtration for Gases

Reticulated foam has excellent filtration properties, but it is important to choose the right type of reticulated foam for your needs. Polyester reticulated foam is the ideal choice for when the filter will come in contact with gases, such as carbon dioxide, oxygen and nitrogen. Its 3D skeletal strand structure minimizes the likelihood of open channels. This flexible, porous foam has an evenly-spaced cell structure with each cell connected to the surrounding cells. This allows for a free flow of air while also providing a large surface area for capturing dust particles.

Polyester-Based Foam Key Features:

  • Easily compressed into sheets of a desired thickness
  • Allows for a free flow of air
  • When manufactured with additives, it can be flame retardant, anti-static, anti-microbial, conductive and electrostatic dissipative
  • Shock absorbent
  • Durable
  • Abrasive resistant
  • Can be cleaned and reused multiple times


Reticulated polyester foam offers a host of uses, including:

  • Sound Proofing
  • Ceramic Filtration
  • Microphones
  • Humidifiers
  • Ventilation Systems
  • Air Conditioners
  • Fuel Tanks
  • Scrubbers
  • Acoustic Foam for Speakers
  • Water Purification Systems
  • And More…
