A paper composite includes activated carbon fibers and inorganic fibers bound together by an organic latex binder. Such a ceramic paper is useful in a variety of applications and is particularly useful as a filter media in the filter unit of an inflator in an automotive airbag. The filter media is particularly suitable for use with non-azide generants within an airbag inflator.
