Air Filter Foams


air filter foam

Recognised around the globe for our outstanding engineering capabilities, customer focus and superior quality products, Technical Foam Services develops and supplies a wide array of reticulated polyurethane foam air and dust filter sheets for many leading OEMs for whom performance, durability and precision are vital. These include:

  • HVAC systems
  • Electronics
  • Automotive
  • Transport
  • Medical HME systems

Blowing the possibilities wide open

Manufactured in high-grade polyester and polyether reticulated foams, these materials are produced by blowing open the cells to create homogeneous and precise porosity and density levels, thus ensuring exact and accurate filtration. As a result, air filter foams offer an improved level of airflow and dust absorption.

In addition to superior performance, our air filter foams provide a wide range of other benefits such as:

  • UV and light resistance
  • Resistance to ageing
  • High tensile strength
  • Washable and re-usable
  • Durability and a longer lifespan
  • Temperature and thermal oxidation resistance
  • Chemical, solvent and contaminant resistance
  • Weldability
  • Oil resistance
  • Fire retardancy to meet FMVSS302 and UL94 standards

HVAC air filter foams

Produced in durable polyester reticulated foam with a high tensile strength, we can manufacture air and dust filter products to meet the highest specifications in terms of shape, size and performance.

Providing an unequivocal level of dust absorption combined with superior resistance to chemicals, solvents, UV, temperature, and ageing, we also supply HVAC air filter foam sheets in fire retardant grades to meet all necessary regulations.


Recognised for the quality and durability of our foam products, our unrivalled engineering capabilities enable us to offer our customers permanent air and dust filter foam solutions with superior performance. These are precision cut and engineered – even in the smallest and most constricted spaces such as those found in computers and electronic goods.

Transport and automotive

We produce both permanent and replaceable air filter foams for the aerospace, rail and automotive sectors. Our products combine excellent dust absorption, oil and contaminant resistance, fire retardancy and durability, and as such, we are the trusted supplier of many well-known names in these sectors.

Medical applications

We manufacture a wide range of medical grade polyether HME air filter foams, in both dry and calcium chloride impregnated forms. We also supply composite HME foams with additional oxygen permeability, bacterial barriers and fluid management where required.

With a written protocol for processing these foams, we have an established relationship with an accredited sterilisation provider, thus enabling us to offer a truly comprehensive service.

Quality and choice

We supply air filter foams in densities and porosity levels ranging from just 8ppi right through to 90ppi, and in a huge choice of thicknesses starting as thin as 3mm. We can also produce composite forms impregnated with carbon to eliminate odours.

Air filter foams can be supplied in custom designed sheets, die-cut, and egg-box profiled shapes. They can also be sewn or ultrasonically welded cylinders for vacuum cleaners, motorcycle or bus filters, and are available in a wide range of colours from black and white to the more vibrant shades of green, yellow and red.
