Abstract: Filters for removing particulate and gaseous organic and inorganic materials from a fluid stream are disclosed. The filter may contain a polymer matrix and optional sequestering agents. Methods of making the filters are also disclosed. Methods of using the filters to remove one or more materials from a fluid stream, such as an air stream, are also disclosed.

Abstract: An air cleaner comprises a cleaning element having a three-dimensional visco-elastic matrix of material for adsorbing airborne particulate matter and for absorbing volatile liquids and a variety of noxious gases. The three-dimensional visco-elastic matrix of material adsorbs particulate matter of many types and sizes and advantageously draws the particulate matter below the surface of the material. To enhance the cleaning properties of the material, the three-dimensional visco-elastic matrix of material may additionally comprise a zeolite to improve the absorption of gases and a metallic additive, such as copper sulfate, to inhibit biological activity. The material forming the three-dimensional visco-elastic matrix may be acrylamide, siloxane, acrylate, or a cellulosic material and may be in the form of fibers or particles.
