OMG, I found the most amazing odor eliminator for the worst fish smell in my fridge. This product works GREAT... Now, I can't find it. It is call FRIDGE-IT activated carbon purple cube. Can anyone back find this? Please, I don't need other product recommendation and don't have a Linens N Things effective by where I know I can buy it.
