The present invention provides methods and devices for rejuvenating a contaminated filter element containing a sorbent laden with one or more contaminants, the device comprising in combination a housing to accommodate the filter element and an oxidizing means to oxidize the contaminants to oxidized products, the housing having an inlet for supplying a carrier gas, an outlet for releasing the oxidized products, and a means for flowing the carrier gas through the inlet to the filter element and flowing the oxidized products from the filter element to the outlet. The contamination filter element can originate from any source, for example, an automobile car cabin, HVAC, paint spray, and others. The filter element can include a sorbent which is a room temperature absorbent such as activated carbon and zeolite, or oxidizing catalysts such as oxides of manganese and copper. The filter element can be heated in situ, e.g., by resistive, radiant, or inductive heating. |
