Office machines, such as electrostatographic reproducing machines, laser printers, and facsimile machines, utilize corona discharge devices, which generate ozone. Some electrostatographic reproducing machines include a film belt arranged in a look having a plurality of such ozone generating corona discharge devices positioned therearound. In order to remove ozone from these machines at the locations where such ozone is generated, an ozone collection system is provided in which each corona device has a hood in proximity therewith connected by a hose to a manifold. The manifold is, in turn, connected by a hose to an ozone-removing canister which includes an air suction pump, a plenum, and an annular filter of activated carbon. The suction pump pulls airstreams into the hoods, which airstreams entrain ozone from proximate each corona device. The velocity of the air entraining the ozone is reduced in the plenum of the canister so that the air diffuses through the filter at a rate slow enough for the filter to be effective in removing the ozone therefrom.
