In industries from medical to manufacturing, filtration plays an vital role in ensuring clean and safe environments, as well as the proper functioning of systems and equipment. A widely used type of filtration media in today’s applications is self-supporting filtration media. These filtration materials have sufficient structural integrity and stability to maintain their shape and filtration properties without the need for additional support structures or frames. Self-supporting filtration media is able to withstand on their own the fluid flow and pressure changes encountered during the filtration process.

What Are Self-Supporting Filters and How They Are Used?

Self-supporting filters are developed from man-made materials that are designed to capture and retain particles or contaminants from fluids. As mentioned previously, they are engineered to work without requiring additional support structures. They are widely used in various industries to improve air quality, purify liquids, maintain sterility, and ensure product integrity by efficiently removing unwanted particles and impurities from fluid streams. Desirable self-supporting filtration media characteristics tend to be versatility, customization ability, and cost-effectiveness.

In any filtration application, success greatly depends upon the selection of the material used to create the filter product. Nonwoven materials have gained significant recognition as a preferred choice for filter media, including self-supporting filtration media due to their unique properties and versatile characteristics.

Structure and Properties of Self-Supporting Filtration Media

Self-supporting filtration media are ideally made from nonwoven materials that are developed with specific physical properties, such as porosity, permeability, and mechanical strength, to effectively capture and retain contaminants from a fluid stream, whether air, gas, or liquid.

The material’s structure and properties are designed to provide the necessary filtration efficiency and capacity while maintaining stability under the applied forces during filtration. Depending on the application requirements, filtration nonwovens can be composed of synthetic polymer fibers such as polyester or polypropylene, natural fibers like cellulose, or a combination of both.
