I bought this for my bathroom to help with eliminating the litter box odor, from my cats. I also bought this product a few years ago for my car and it works fantastic it helped get the smoke smell out of my car not that I smoke but some of my friends do. So far the litter box smell is diminishing as I knew it would. It's nice to have this around it helps with not having to constantly pay for scented sprays plus it is a natural product and it doesn't cost anything to recharge.
