The fragrance dispenser may comprise a plurality of receptacles and the porous diffuser layer comprises a plurality of sections that are individually removable to uncover each receptacle. The fragrance dispenser could comprise a removable cover sheet that is peelably detachable from the porous diffuser layer. Porous diffuser layer could be an organic polymeric nonwoven web and/or the receptacle is made of a thermoplastic organic polymeric resin. The fragrance dispenser may further comprise a secondary diffuser layer that has 50% more permeability that the porous diffuser layer.
