Review on All Prime Bamboo Charcoal Bags Odor Absorber - 4 Pack: Large 500g Bags for Powerful Natural Odor Elimination and Air Purification - Charcoal Deodorizer and Activated Charcoal Odor Absorber for Home Use by Connie Love

I was skeptical of charcoal air fresheners but I have 2 dogs that stink in the bedroom so thought they might be worth a try. I put 2 bags in their room and they started working from the 2nd day. There is no smell in the room. No smell, just what I wanted! No more dog smell! I put the other two under the front seats of my car because I am a smoker and thought they would work because of the dog smell, although if they only work in the car that would be great. Well, they work there too! The smoke smell is completely gone, no. But MUCH better! I will definitely be buying more in smaller sizes for things like smelly shoes.
