Activated Carbon as a Room Deodorizer

I saw an episode of Food Detectives a while back where Ted Allen mentioned that the best way to remove refrigerator odor was activated carbon.  This was supposedly better than baking soda.  Activated carbon can be found at the local pet supply store in the fish area.  I decided to give try this in our bathrooms.  But instead of just putting a cupful out I put it in a mason jar and punched holes with our monogram in it, just to make it look more decorative.

Here is the Food Detectives episode:
