A contaminant-removal filter for removing contaminants from a gas stream, such as air, the contaminants being acidic, basic, or carbonyl-containing compounds. The filter has a porous or fibrous body that includes a plurality of passages extending from a first, inlet face to a second, outlet face, the passages providing flow paths. The body has an active material impregnated throughout the substrate. The active material present is selected based on the contaminant to be removed. |
