PFAS and Alternatives: Sustainable Filtration Solutions for Air and Liquid Filtration

Per- and polyfluoroalkyl substances (PFAS) have emerged as a critical concern in the global push toward sustainability due to their persistence in the environment, potential health risks, and increasing regulatory restrictions. In the filtration industry, where PFAS-containing materials such as micro glass media and PTFE membranes have been widely used for air and liquid filtration, there is a growing demand for environmentally friendly alternatives that maintain high performance standards without compromising health and environmental safety.

     This paper explores the properties and environmental persistence of PFAS, the associated health risks, and the current regulatory landscape driving the search for alternative materials. It also highlights innovative filtration technologies that provide PFAS-free solutions, focusing on advanced nanofiber technologies, bio-based polymers, and composite materials engineered for high filtration efficiency and sustainability.
