Filtration felt is a highly effective nonwoven material for filtration applications. Polyester felt, polypropylene felt, and other needled felt materials can be used to filter air, liquids, gases, and more. Our filtration felts are available in a range of densities and thicknesses, and in different sizes and order quantities to suit your requirements. From air filtration to liquid filtration, we offer the right nonwoven media for virtually any filtration application, including furnace and HVAC systems, baghouse dust collectors, liquid pressure vessels, and liquid filter presses—the list goes on.
