Porous Metal Filters’ goal is to utilize its extensive experience to promote porous metal filters for the next generation of advanced filtration and separation products.

Porous metal filter elements have proven to be bleeding-edge technology widely practiced in many industries from clarification of natural fruit juices to water treatment and waste streams containing detergents, polymers, and organic solvents.

SINTERPORE® filter elements cartridges are available in a broad range of micron ratings, permeability, and alloys.

About Our Company

Porous Metal Filter Inc. (PMF), was established in 2008, has a collective knowledge from over 120 years of experience in porous metal filter media, filtration experience, and fabrication of filtration products. The goal of Porous Metal Filters is to utilize this experience to promote the use of porous metal media in the next generation of advanced filtration and separation products.

At Porous Metal Filters, we manufacture diffusion-bonded porous metal sheets, multi-layered laminate filter media, fabricated filtration elements, leaves, cylinders, cones and more. The Porous Metal Filters SinterPore® product offerings of SLS (single layer sintered), MLS (multi-layer sintered), and CLS (custom layer sintered) are comprised of single and multiple layers of woven stainless wire mesh, non-woven metallic fibers, and perforated sheet and foils. This is used for filtration, separation, flow control, noise reduction, powder fluidization, and many other uses.

The standard materials of construction are 304, 304L, 316, 316L stainless steel. Custom materials such as Alloy 20, Hastelloy C-22 and 276, Monel, and Inconel 600 and 625 are available upon request.

The SinterPore® materials are designed for high-temperature and corrosive environments where the controlled pore size, pore geometry, and permeability characteristics are a prerequisite for optimum filtration. These properties are required in a variety of applications including aerospace, automotive, chemical, pharmaceutical, polymer, food & beverage, oil & gas, and power generation industries.

In addition to filtration media and element manufacture, Porous Metal Filters offers consulting and engineering services including product testing, process evaluation/optimization, and training in filtration principles.

At Porous Metal Filters, we manufacture products to the highest current industry standard and are certified to meet ISO 9001 requirements.
