FILTRATION MEDIA AND METHODS

The technology disclosed herein relates to a filter media having a fiber matrix and a binder distributed throughout the fiber matrix. Conductive particles are impregnated in the binder matrix and a flame retardant distributed throughout the fiber matrix and the binder matrix. The filter media can be incorporated into various types of media pack assemblies for air filtration including coiled media, pleated media, and stacked filter media. A method is also disclosed where conductive particles are distributed in a binder and a fiber matrix is impregnated with the binder. A solution containing at least 5% flame retardant solids is formed and the fiber matrix is saturated in the solution. The saturated, impregnated fiber matrix is dried and cured.
