Very efficient! Better than baking soda!
I ordered this item to deodorize my refrigerator instead of using baking soda and replacing every monthly So far, it has made an incredible difference and we have no odors in our refrigerator. We can't notice certain foods are in there which with baking soda, it would still have a smell (strong dishes such as fish). It is also more convenient than baking soda as I have previously spilled some baking soda when pushing foods around. With this, I have no worries with that possible issue. Overall, very happy with my purchase.
