I know and use a product called FRIDGE IT. It is an inexpensive activated carbon odor absorber that works incredibly. Really eliminates odors. It's not a silver disk but a cute little purple cube. Frankly, I've tried many other products and other "odor absorbers" for fridge and nothing works as well as this product. Works so well, I know use it now everywhere around house including smelly trash under the sink and even my 2 cat litter boxes. Yes, works that well. It's the activated carbon. I highly recommend it and you can get it directly from company on line. Email them at customerservice@innofresh.com for easy order form.
Anyone else love this product?
