Abstract

See full text

A contaminant-removal filter for removing acidic contaminants from a gas stream, such as air. 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 a base or alkaline material, such as potassium carbonate, and a promoter, such as potassium iodide, impregnated throughout the substrate. The filter is free of any humectants.
