Query: Doesn't work

I purchased this to put inside my small car (hatchback size) to help with the musty scent due to residual water damage to the upholstery. I've had it for about a month and so far it hasn't done anything at all to reduce the musty smell or humidity in the car on certain days. A box of Arm and Hammer Baking Soda (the kind that you put in your fridge) works better for odors.I've tried other products and most of them are heavily-scented and I was hoping that this would be a nice alternative. Sadly, not.
