Abstract : Means for removing contaminants from an air stream are disclosed that at the same time provides a cost effective apparatus for training firefighters. HOPCALITE is used to remove carbon monoxide while other compositions remove particulates, water and organic vapors, and carbon dioxide. The present invention is an apparatus comprising layers of filter and chemical parts through which air containing carbon monoxide with or without carbon dioxide, hydrocarbons and nitrogen oxides passes and is scrubbed for inhalation by a user. The apparatus further comprises an adaptation to, or replication of, the canister of an operational oxygen breathing apparatus, wherein the canister now is provided with an actuable aperture to permit the canister to be used as a flow-through device in an adapted or replicated operational breathing apparatus wherein the bag(s) are inflated with the exhaled breath of the user in lieu of air available for inhalation.
