An adsorption bed arrangement includes a plurality of adsorption elements, a housing, and a gasket member. Each of the adsorption elements has a first adsorptive media and a second adsorptive media contained within a respective element. The first and second adsorptive medias remove different contaminants from the incoming air stream. For example, the first adsorptive media removes acidic contaminants and the second adsorptive media removes basic contaminants. Each of the adsorption elements is selectively openable to provide access to the adsorptive medias. The housing defines an interior, a plurality of inlet openings, and a plurality of outlet openings. The adsorption elements are positioned within the housing interior and the housing is selectively openable to provide access to the adsorption elements. The gasket member is between the housing and the adsorption elements. A method for changing filtering media in an adsorption apparatus includes steps of removing an access panel from an adsorption bed housing to expose a cover member covering an end of an adsorption element; removing the cover member from the end of the adsorption element to expose filtering media within the element; and pouring the filtering media from the element.
