Environmental Air Sponge from Office Depot...Has anyone used it?

I've used it and it doesn't work. Just covers up odors. Don't waste your money. Better Idea. Use activated carbon which is totally fragrance free and no chemicals and literally absorbs and eliminates odors. I found a product that I've used for years and so many of my friends as well. It is called FRIDGE IT activated odor absorbers. Little purple cube that has an incredible carbon filter inside for only a couple of dollars. You can find it in kitchen gadget sections at stores like walmart and linens and things. Haven't found it at Office depot. I use this product everywhere including fridge, under sinks and litter box. Friends use it in cars for smoke and pet odors - it's that good. Definitely worth trying.
