    摘要: A contaminant-removal filter for removing basic 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 an acidic material, such as citric acid, and at least one of a preservative and a stabilizer impregnated throughout the substrate. The filter is free of any humectants.

    摘要: A contaminant-removal filter for removing carbonyl-containing compounds from a gas stream, such as air. Examples of common airborne carbonyl-containing compounds include ketones, including acetone, and aldehydes, including formaldehyde. 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 reactant material impregnated throughout the substrate. The reactant material is a sulfite, bisulfite, oxidant, or derivative of ammonia, specifically high molecular weight and stable amines. Strong alkali (basic) materials are particularly suitable for aldehyde removal. The filter is free of any humectants.
