The best foams for filtration applications

It is important to understand the best foam to meet your needs. Filter foams have a multitude of industrial applications and are important to maximize performance, longevity and cost. Filtration foams are specifically designed to perform this task well due to their density and strength.

Industrial filtration foams

Filtration foams have the appropriate durability and permeability to allow liquids or solids (depending on their application) to pass through them while blocking out the unwanted objects or particles. The durability of foams is one of the things that makes foam an excellent solution for filtration applications.

Generally, less dense open cell foam is used for filtration because it has a less rigid structure that holds up more over time but closed-cell foams can be used for specific applications. The best air filter foams will meet the High-efficiency particulate air (HEPA) performance standards. 

Other good qualities of filter foams include: 

  • Low odor 
  • Lightweight 
  • Anti-microbial 
  • High chemical resistance 
  • High tensile strength 
  • Elongation and tear-resistant

Additives can be added to the foam to make it flame retardant, anti-static or static dissipative which further extends the usefulness of the filtration foam.

What are the best types of filter foam?

Reticulated foam is the most common and most effective type of foam used for filtration because the reticulation process removes a portion of the foam’s cell membranes and imprutities.  The lattice-like appearance of reticulated polyurethane foam is particularly useful as a filter foam. This allows the foam to be used in applications like fluid management, cleaning products, combustible engines, air compressors, electronic devices, and in many other industries. Reticulated foam comes in two different types: reticulated polyester and reticulated polyether. Other open-cell foams like ether polyurethane foam and ester polyurethane foam are also good for filtration because of their natural toughness.
