    摘要: The present invention overcomes the limits of activated carbons, ion exchange resin beads and fibers, and liquid form ion exchangers for acid, base, or VOCs gases removal by providing a filtration assembly for the filtration of chemical contaminants and particulates from an air or gas stream, the assembly having a low pressure-drop structure. The filtration assembly includes a low-pressure drop chemical filter, a low-pressure drop particulate filter, and an air transportation device, such as a fan or blower, all combined in a housing.

    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.
