What is Reticulated Filter Foam?

Reticulated filter foam is a specialized form of polyurethane foam that has undergone a controlled reticulation process. This method removes the cell membranes, leaving behind a 3D lattice of interconnected strands—creating an open-cell foam with exceptional porosity. It is used for both air and liquid filtration in various industries.

Karefoam manufactures both:

  • Polyester filter foam – Known for superior mechanical strength and chemical resistance.
  • Polyether filter foam – Excellent for humid or wet environments due to its hydrolysis resistance.



Benefits of Reticulated Polyurethane Foam:

  • High porosity and air permeability
  • Custom pore size (PPI) options
  • Washable and reusable
  • Lightweight and flexible
  • Available in multiple densities, colors, and formats

Whether you need a custom filter foam manufacturer for PU foam filtration or filter foam for industrial use, Karefoam’s technology delivers both quality and versatility.
