A bin deodorizer apparatus 10, the apparatus comprising a first part 12 and second part 14. The first part 12 comprises a permeable structure 16. The permeable structure 16 of the first part 12 comprises activated carbon. The second part 14 comprises a permeable structure 18. The permeable structure 18 of the second part 14 comprises activated carbon and potassium permanganate. Preferably, the volume of the first part 12 is greater than the volume of the second part 14. Preferably, the structure of the first part 12 is an open cell foam while the permeable structure of the second part 14 is a non-woven structure, e.g. a non-woven fabric comprising polymer fibres. The first and second parts may be bound together with an adhesive, e.g. web adhesive. The apparatus may further comprise a base 22. The base 22 may comprise a lip 24 extending beyond the first and second parts. The base may comprise means for attachment to the inside surface of a bin.
