[ What is claimed is:] [1.]1. A filter assembly for filtering gas containing contaminating particulates, comprising a fail-safe/regenerator device and an elongated filter element, within a hot gas cleanup system pressure vessel having a hot particulate contaminated gas entry, said filter assembly comprising: a filter housing, said filter housing having a peripheral side wall, said side wall defining an interior chamber; a porous, elongated filter element body attached to the bottom end of the fail-safe/regenerator device; and a one-piece, fail-safe/regenerator device, having a top and bottom end, disposed within the interior chamber of the filter housing, said fail-safe/regenerator device comprising: a 70% to 92% porous, rigid, static bed of generally interlocked wires, the wires having an aspect ratio over about 30, with, optionally, at least some interlocked wires having an aspect ratio over about 150, disposed between a top and bottom set of supports, said wires effective to trap contacting contaminating particulates permanently.
